Buschke–Ollendorff syndrome is a rare, inherited condition that affects the skin and the bones. In the skin, people develop small, firm bumps called connective tissue nevi (they can be elastin-rich “elastomas” or collagen-rich “collagenomas”). In the bones, people often have many small, round, dense spots called osteopoikilosis that show up on X-rays. Most people feel well. The skin bumps are usually harmless and painless. Bone spots are usually found by chance. The condition is caused by changes (mutations) in a gene called LEMD3, which sits in the inner membrane of the cell nucleus and helps control growth signals, especially the TGF-β and BMP pathways. BOS is usually passed down in autosomal dominant fashion, so a parent with BOS has a 50% chance of passing it to each child. JAMA Network+3DermNet®+3MedlinePlus+3
Buschke–Ollendorff syndrome (BOS) is a hereditary condition that mainly affects the skin and bones. On the skin it causes firm, usually painless lumps called connective tissue nevi (elastomas or collagenomas). In bone it is frequently associated with osteopoikilosis—small, round “spotted bone” areas seen on X-rays that are typically harmless. Most people feel well and discover BOS during skin or imaging evaluations done for other reasons. MedlinePlus+1
BOS is usually autosomal dominant—a person with the condition has a 50% chance of passing the altered gene to a child. Some individuals carry the gene change but have few or no noticeable findings (variable expressivity and reduced penetrance). Families often come to attention when several relatives share similar skin findings or when “spotted bone” is seen incidentally. DermNet®+1
Most BOS cases are caused by loss-of-function variants in LEMD3 (also known as MAN1), a gene that helps keep in check cell signaling pathways called TGF-β and BMP (bone morphogenetic protein). When LEMD3 does not work properly, those pathways can signal more than they should in skin and bone, contributing to the nevi and bone spots doctors see. This genetic mechanism has been shown in families with BOS and related conditions. Nature+1

Historical: “Osteopathia condensans disseminata with skin nevi” (older literature connecting bone and skin)
These names reflect the same clinicogenetic spectrum linking connective tissue nevi and osteopoikilosis due to LEMD3 variants. NCBI+1
Types
Because BOS can look different from person to person—even in the same family—doctors often think in “types” by what is mainly affected:
Skin-predominant BOS: Many connective tissue nevi (elastomas or collagenomas) with few or no symptoms from the bones. JAAD Case Reports
Bone-predominant BOS: Typical osteopoikilosis on X-rays, often found by accident, with few skin bumps. PubMed
Combined skin + bone BOS (classic BOS): Both connective tissue nevi and osteopoikilosis are present. This is the classic picture. JAMA Network
BOS with melorheostosis overlap (rare): Some families or individuals also have melorheostosis, a thick “flowing” bone overgrowth. The link to LEMD3 is complex; melorheostosis can also arise through somatic mosaic mutations (e.g., MAP2K1) independent of germline LEMD3. Nature+1
Minimal-expression BOS: Very subtle or no skin findings and small, non-specific bone islands, but a positive family history and LEMD3 mutation. JAMA Network
Causes
Although LEMD3 loss-of-function is the root cause, many biological details help explain why BOS looks the way it does. Here are clear, bite-size “causes/mechanisms” that together create the syndrome:
LEMD3 gene mutation (germline): The single core cause for BOS; most often loss-of-function variants. Nature+1
Autosomal dominant inheritance: One altered copy is enough; 50% transmission risk per child. JAMA Network
Haploinsufficiency: Too little working LEMD3 protein leads to abnormal tissue signaling. Nature
TGF-β pathway disinhibition: LEMD3 normally restrains TGF-β signals; reduced LEMD3 lets the pathway run “hot,” changing matrix production. MedlinePlus
BMP pathway disinhibition: Similar loss of braking on bone morphogenetic protein signals affects bone density patterns (bone islands). MedlinePlus
SMAD signaling imbalance: LEMD3 interfaces with SMADs; altered SMAD control shifts transcription of matrix and bone genes. MedlinePlus
Abnormal elastin/collagen deposition: Explains elastomas and collagenomas in the skin (connective tissue nevi). ScienceDirect+1
Disrupted inner nuclear membrane function: LEMD3 (also called MAN1) sits in the inner nuclear membrane; structural/signaling defects follow. PMC
Variable expressivity: Same family, different severity—due to modifiers and environment. JAMA Network
Incomplete penetrance: Some mutation carriers show very mild or no obvious lesions. JAMA Network
Tissue-specific effects: Skin fibroblasts and bone cells respond differently to pathway imbalance, giving the dual (skin + bone) pattern. ScienceDirect
Developmental timing: Lesions often appear in childhood/adolescence when connective tissue and bone modeling are active. DermNet®
Matrix remodeling loops: Abnormal TGF-β/BMP activity alters feedback loops that regulate collagen/elastin turnover. MedlinePlus
Genotype–phenotype diversity: Nonsense, frameshift, splice, or missense changes in LEMD3 can yield different mixes of skin/bone signs. Wiley Online Library
Interaction with other genes (modifiers): Background variation likely shapes severity; still an active research area. SpringerLink
Somatic mosaicism (for melorheostosis overlap): Some MEL lesions arise from post-zygotic mutations (e.g., MAP2K1) separate from LEMD3. SpringerLink
Micro-environmental mechanics: Local stress on skin/bone may influence nevus appearance or radiographic density (hypothesized). PubMed
Age-related reveal: Bone islands persist; skin lesions may become more noticeable over time. PubMed
Benign biology: The process changes structure more than function—hence the often mild course. PubMed
Rare complications from pathway spillover: In a minority, heart valves or hearing can be affected (see symptoms). Wikipedia
Symptoms and signs
Small, firm skin bumps (papules/plaques): Usually skin-colored to yellowish, smooth, and painless; often on trunk, buttocks, limbs. These are connective tissue nevi. JAAD Case Reports
Elastomas: Bumps rich in elastin fibers; may feel rubbery. ScienceDirect
Collagenomas: Bumps rich in collagen; feel firm. NCBI
Clusters or scattered lesions: Can be numerous (“disseminated”) or grouped. NCBI
Usually painless skin: Itching or tenderness is uncommon. JAAD Case Reports
Normal general health: Most people feel fine and function normally. PubMed
Osteopoikilosis (bone islands): Seen on X-rays as many small, round/oval dense spots near joints; usually no pain. Nature
Occasional bone/joint pain: Some report mild aching or stiffness, especially if melorheostosis coexists. PubMed
Limited range of motion (rare): More often tied to melorheostosis than to BOS alone. SpringerLink
Cosmetic concern: Skin appearance may bother some patients. JAAD Case Reports
Family history: A parent, child, or sibling with similar lesions or bone spots. JAMA Network
Hearing issues (rare): Reports of conductive or sensorineural hearing loss exist but are uncommon. Wikipedia
Heart valve problems (very rare): Occasional associations like aortic stenosis were reported; routine symptoms are unusual. Wikipedia
No systemic inflammation: Fevers, weight loss, or rashes typical of inflammatory disease are not expected. PubMed
Normal life expectancy: BOS itself is benign in most cases. PubMed
Diagnostic tests
A) Physical examination (bedside)
Full skin exam: Doctor looks and feels for firm, smooth, painless papules/plaques that suggest connective tissue nevi (elastomas/collagenomas). Distribution and number help. JAAD Case Reports
Lesion palpation: The bumps feel rubbery/firm and non-tender; this supports a benign connective tissue nevus rather than an inflamed lesion. NCBI
Family screening at the bedside: Quick check of close relatives for similar skin bumps or known bone spots, because BOS is autosomal dominant. JAMA Network
Joint and limb check: Range-of-motion and localized tenderness; important if MEL is suspected (stiffness or deformity). SpringerLink
General exam for rare complications: Basic cardiac auscultation and otoscopic exam if there are symptoms (murmur, hearing complaints). Wikipedia
B) Manual/office tests (simple clinic maneuvers)
Dermatologist’s clinical dermoscopy (if available): Non-invasive magnified view; may show uniform structure consistent with nevi (used adjunctively; histology confirms). JAAD Case Reports
Photographic mapping: Serial photos to document stability or slow changes of skin lesions over time (helps reassurance and monitoring). PubMed
Pedigree charting: A simple three-generation family tree to map inheritance and identify at-risk relatives. JAMA Network
Functional screen: Basic gait/hand function checks when bone symptoms are reported, looking for MEL-related limitations. SpringerLink
Pain scales/PROs: Simple questionnaires capture any mild bone/skin discomfort and guide follow-up. PubMed
C) Laboratory & pathological tests
Skin biopsy (histology): Confirms connective tissue nevus. Elastomas show increased, thickened, or fragmented elastic fibers; collagenomas show increased collagen bundles. Special stains (e.g., Verhoeff–Van Gieson, Orcein) highlight elastin. NCBI+1
Genetic testing for LEMD3: The key confirmatory test. Finds heterozygous loss-of-function variants in most classic BOS/osteopoikilosis cases. Wiley Online Library+1
Targeted variant testing in relatives: If a family mutation is known, focused testing can clarify who carries it and who may need imaging/skin checks. JAMA Network
Routine blood tests: Typically normal; BOS is not an inflammatory or metabolic disorder. Lab tests are mainly to rule out look-alikes if history is unclear. PubMed
D) Electrodiagnostic / physiologic tests (as needed)
Audiometry (hearing test): Done when a patient reports hearing changes; looks for conductive or sensorineural loss (rare in BOS). Wikipedia
Electrocardiogram (ECG): Not routine, but may be ordered if there are symptoms suggesting heart valve issues or dizziness/palpitations; ECG helps overall cardiac evaluation alongside echocardiography. Wikipedia
E) Imaging tests
Plain X-rays (skeletal survey): The hallmark test for osteopoikilosis—shows many small, symmetric, round/oval sclerotic foci near joints (epiphyses/metaphyses) in hands, feet, pelvis, long bones. Nature
Bone scintigraphy (bone scan): Osteopoikilosis lesions are “cold” or normal on bone scan, which helps distinguish from metastatic disease (hot). DNB
CT or MRI (selected cases): Used if lesions are atypical, symptoms are focal, or melorheostosis is suspected (flowing cortical hyperostosis). SpringerLink
Echocardiography (if symptomatic): Imaging of heart valves when there are signs or symptoms suggesting rare cardiac involvement, such as aortic stenosis. Wikipedia
Non-pharmacological treatments (therapies & others)
Important: These options are supportive; pick only what matches your symptoms and goals with your clinician. There is no evidence that lifestyle or procedures “cure” BOS, but they can improve comfort, function, or appearance.
Education & reassurance. A careful explanation—that BOS skin lesions are benign and osteopoikilosis spots do not indicate cancer—reduces anxiety and prevents unnecessary biopsies or scans. Clear counseling is emphasized because osteopoikilosis can be mistaken for metastases if doctors are unfamiliar with it. PubMed+1
Purpose: Reduce fear, avoid overtreatment.
Mechanism: Knowledge changes decisions; clinicians document BOS in the record to guide future imaging reads. ScienceDirect
Watchful waiting with routine care. For most, the best approach is no active treatment—just routine skin care and periodic review if anything changes. This fits evidence that BOS is stable and benign for many. OUP Academic
Purpose: Avoid procedures that offer little benefit.
Mechanism: Natural history is favorable; monitoring catches rare exceptions. OUP Academic
Dermatology skin-care plan. Emollients and gentle skin care can improve texture and comfort around lesions even though they do not remove nevi. This standard supportive care is widely used for benign dermatoses. JAAD Case Reports
Purpose: Ease dryness/irritation; improve look/feel.
Mechanism: Moisturizers reduce transepidermal water loss and soften the stratum corneum.
Targeted CO₂ laser resurfacing for selected raised lesions. For patients bothered by thicker plaques, experienced dermatologic surgeons may use ablative lasers to smooth the surface. Evidence shows CO₂ lasers remodel collagen/elastin and improve texture in connective tissue disorders, though data for BOS specifically are limited; shared decision-making is essential. JAMA Network+1
Purpose: Cosmetic smoothing.
Mechanism: Fractional/ablative energy removes/reshapes dermal tissue, stimulating remodeling. Wiley Online Library
Non-ablative lasers (e.g., 1540–1550 nm) as an adjunct. Some centers use non-ablative lasers to stimulate collagen and elastin with less downtime. Evidence in connective tissue diseases suggests lasers can be a useful adjunct—results vary. PubMed+1
Purpose: Subtle texture improvement.
Mechanism: Dermal heating triggers controlled wound-healing and matrix remodeling.
Surgical excision of a focal, bothersome lesion. If a single plaque catches on clothing or is cosmetically distressing, simple excision can remove it. This treats the lesion you remove; others may remain the same. JAAD Case Reports
Purpose: Remove a symptomatic/annoying lesion.
Mechanism: Definitive local removal.
Psychological support/body-image counseling. Visible skin differences can affect self-esteem. Support groups or counseling improve coping and quality of life in many skin conditions and can be helpful in BOS. MedlinePlus
Purpose: Improve well-being.
Mechanism: Cognitive and social strategies reduce distress.
Family genetic counseling. Because BOS is autosomal dominant, counseling helps relatives understand recurrence risk and testing options. DermNet®
Purpose: Informed reproductive and screening choices.
Mechanism: Explains 50% transmission risk and variable expressivity.
Physical therapy for activity-related aches. A small subset report joint discomfort; a brief PT program can improve flexibility/strength and reduce secondary pain. OPK itself usually needs no treatment. Cleveland Clinic+1
Purpose: Reduce musculoskeletal discomfort.
Mechanism: Graded exercise and mechanics optimization lessen strain.
Activity pacing/ergonomics. For people who notice aching with repetitive tasks, pacing and ergonomic adjustments can reduce flares without medication. Cleveland Clinic
Purpose: Comfort during work/sport.
Mechanism: Decreases cumulative load on symptomatic areas.
Sun protection. Standard photoprotection can help overall skin health and scar quality after procedures, though BOS lesions themselves are not caused by sun. JAAD Case Reports
Purpose: Better skin outcomes.
Mechanism: Reduces UV-related damage and post-procedure dyspigmentation risk.
Accurate imaging documentation. If you have OPK, ask radiology to note BOS/osteopoikilosis on reports. This prevents future alarm for “suspicious spots.” Bone scintigraphy is typically normal in OPK and can aid differentiation. PubMed
Purpose: Avoid misdiagnosis.
Mechanism: Provides a stable comparator for future studies.
Scar-care after procedures. Silicone gel and gentle massage are standard after minor dermatologic surgery to optimize cosmetic results. JAMA Network
Purpose: Better healing and appearance.
Mechanism: Occlusive hydration and mechanical modulation of collagen.
Shared decision-making about cosmetic goals. Because evidence for lesion-directed procedures in BOS is limited, agreeing up front on what improvement looks like prevents disappointment. PubMed
Purpose: Align expectations.
Mechanism: Clarifies benefits/limits of adjunct procedures.
Periodic skin checks if lesions change. While BOS lesions are benign, any new, rapidly changing, painful, or ulcerated area deserves evaluation to rule out unrelated problems. MedlinePlus
Purpose: Safety net.
Mechanism: Early evaluation of outliers.
(Items are generally not necessary for BOS and would duplicate themes above; high-quality guidance emphasizes reassurance and individualized supportive care rather than long lists of mandatory therapies.) OUP Academic
Drug treatments
Key truth: No medication is FDA-approved specifically for BOS. The drugs below are common, label-supported options clinicians may use to treat symptoms some BOS patients report (e.g., musculoskeletal pain after activity, post-procedure care, itch, or anxiety around procedures). Always individualize dosing and check interactions. Sources: FDA drug labels (accessdata.fda.gov).
Acetaminophen (paracetamol).
Class: Analgesic/antipyretic. Typical adult dose: 325–1000 mg per dose, max generally ≤3,000–4,000 mg/day depending on product and liver risk. When: As needed for mild pain. Purpose: First-line pain relief without GI irritation. Mechanism: Central COX inhibition to reduce pain/fever. Side effects: Usually well tolerated; overdose can cause liver injury—heed max daily dose. Cleveland Clinic
FDA label: accessdata.fda.gov (acetaminophen). Cleveland Clinic
Ibuprofen.
Class: NSAID. Dose: Common OTC adult 200–400 mg every 6–8 h (max per label). When: Activity-related aches. Purpose: Anti-inflammatory pain relief. Mechanism: COX-1/COX-2 inhibition lowers prostaglandins. Side effects: GI upset/ulcer risk, renal effects; avoid in certain cardiac/renal/GI conditions and pregnancy late term (follow label). FDA label: accessdata.fda.gov (ibuprofen). Cleveland ClinicNaproxen.
Class: NSAID. Dose: 220–250 mg every 8–12 h (OTC/Rx products vary). Purpose/Mechanism/Effects: Similar to ibuprofen; longer duration; same cautions. FDA label: accessdata.fda.gov (naproxen). Cleveland ClinicTopical diclofenac gel 1%.
Class: Topical NSAID. Dose: Per label by joint/area. Purpose: Local pain with lower systemic exposure. Mechanism: Local COX inhibition. Side effects: Local irritation; systemic NSAID warnings still apply. FDA label: accessdata.fda.gov (diclofenac gel). Cleveland ClinicTopical lidocaine 4–5% (patch/cream).
Class: Local anesthetic. Dose: As per product (e.g., patches up to 12 h on/12 h off). Purpose: Numbs focal tender areas or post-procedure discomfort. Mechanism: Sodium channel blockade. Side effects: Skin irritation; rare systemic effects if misused. FDA label: accessdata.fda.gov (lidocaine topical). Cleveland ClinicDuloxetine.
Class: SNRI. Dose: Common 30–60 mg/day. Purpose: Chronic musculoskeletal pain in people who also have mood/anxiety symptoms; label includes chronic MSK pain. Mechanism: Central serotonin/norepinephrine modulation. Side effects: Nausea, sleep changes; boxed warnings apply. FDA label: accessdata.fda.gov (duloxetine). Cleveland ClinicAcetaminophen–opioid combinations (short term only, when strictly necessary).
Class: Opioid analgesic combo. Dose: Per label, lowest effective dose for shortest time. Purpose: Rescue for acute severe pain (e.g., immediate post-procedure). Mechanism: µ-opioid receptor agonism + acetaminophen. Side effects: Sedation, constipation, dependence risk; boxed warnings. FDA label: accessdata.fda.gov (hydrocodone/APAP). Cleveland ClinicNon-sedating antihistamines (cetirizine, loratadine).
Class: H1 blockers. Dose: Typical 10 mg/day (product-specific). Purpose: Itch relief if lesions or healing sites itch. Mechanism: Blocks histamine H1 receptors. Side effects: Drowsiness (cetirizine) or minimal. FDA label: accessdata.fda.gov (cetirizine/loratadine). Cleveland ClinicTopical corticosteroids (short courses).
Class: Anti-inflammatory steroid. Dose: Potency and duration per lesion/location. Purpose: Calm procedure-related dermatitis or irritation around nevi; not a BOS cure. Mechanism: Down-regulates inflammatory genes. Side effects: Skin atrophy with overuse. FDA label: accessdata.fda.gov (triamcinolone topical). Cleveland ClinicPetrolatum/medical-grade emollients.
Class: Skin protectant. Use: Liberal application post-procedure or for dryness. Purpose: Barrier support. Mechanism: Occlusion reduces TEWL. Side effects: Minimal. FDA monograph/OTC protectants: accessdata.fda.gov. Cleveland Clinic
(Given BOS lacks disease-specific pharmacotherapy, additional entries beyond these core symptomatic options would repeat similar pain/skin-care mechanisms. High-quality guidance stresses that most BOS patients need few or no medicines.) OUP Academic
Dietary molecular supplements
Note: No supplement treats BOS itself. Discuss all supplements with your clinician, especially around surgery or if pregnant.
Vitamin D (with or without calcium). For people who are deficient, correcting vitamin D supports general bone/skin health. Routine high-dose use is not specific to BOS; test and replete if low per guidelines. OUP Academic
Omega-3 fatty acids (fish oil). May modestly reduce general musculoskeletal discomfort in some people; not BOS-specific. Stop before procedures if instructed. OUP Academic
Collagen peptides. Some small studies in other dermatoses show texture/hydration benefits; effects in BOS are unproven. ResearchGate
Ceramide-rich oral/skin-barrier nutrients. Aim to support skin barrier; strongest evidence remains for topical ceramides rather than oral forms. JAAD Case Reports
Protein sufficiency (whey/soy if needed). Adequate protein helps wound healing after minor procedures. JAMA Network
Zinc (if deficient). Important for wound healing; excess can cause copper deficiency—avoid unsupervised high doses. JAMA Network
Vitamin C (diet first; short-term supplementation if low). Supports collagen cross-linking in healing. JAMA Network
Probiotics (strain-specific). Limited dermatology data; no BOS evidence—use only if there’s another clear indication. ResearchGate
Hyaluronic acid (oral/topical). Topical forms aid hydration; oral data are mixed; not BOS-specific. ResearchGate
Multivitamin (basic). Reasonable if diet is poor; avoid megadoses. MedlinePlus
Drugs Immunity-boosting / regenerative / stem-cell–related
Plain truth: There are no proven immune-boosting, regenerative, or stem-cell drugs for BOS. Below are context notes used in general medicine or procedural healing—not BOS treatment claims.
Topical platelet-rich plasma (PRP) (procedure, not a drug): explored for scar/skin rejuvenation; investigational for BOS; discuss risks/benefits. Wiley Online Library
Recombinant human growth factors in wound products (e.g., PDGF in specific dressings): used for select chronic wounds; not indicated for BOS lesions. JAMA Network
Retinoids (topical tretinoin). Promote dermal remodeling in photoaging; can be used around procedural scars, not to treat BOS nevi per se. JAMA Network
Silicone-based scar therapy (OTC device/gel): improves scar appearance after excisions/laser; safe, non-drug. JAMA Network
Antioxidant blends (vitamin C/E): sometimes used peri-procedure for skin quality; evidence modest; avoid high doses pre-op without guidance. JAMA Network
Stem-cell therapies: Not approved for BOS; outside clinical trials these are not recommended. MedlinePlus
Surgeries or procedures
Excisional removal of a single lesion. What: Minor outpatient cut-out with stitches. Why: A focal plaque catches or causes cosmetic bother; pathology confirms diagnosis. JAAD Case Reports
CO₂ laser ablation/resurfacing. What: Vaporizes thin layers of skin to smooth raised areas. Why: Cosmetic contouring in selected cases by experienced surgeons. JAMA Network
Fractional non-ablative laser. What: Microscopic dermal heating columns without open wound. Why: Subtle texture improvement with less downtime; as adjunct. PubMed
Diagnostic skin biopsy. What: Small punch or excision to confirm elastoma/collagenoma. Why: Clarify diagnosis when presentation is atypical. NCBI
Orthopedic evaluation (rare). What: Assessment if pain suggests another condition or, rarely, coexisting melorheostosis. Why: Ensure no other cause of pain/limitation; BOS bone spots themselves usually need no surgery. OUP Academic
Ways to prevent problems
Share your BOS/osteopoikilosis diagnosis with radiologists to avoid misreads. PubMed
Avoid unnecessary biopsies/imaging—ask if findings fit BOS. OUP Academic
Use sun protection, especially after procedures. JAMA Network
Maintain gentle skin care to reduce irritation of plaques. JAAD Case Reports
Pace activities if you notice aches; adapt ergonomics. Cleveland Clinic
Seek genetic counseling for family planning. DermNet®
Keep vaccinations and general health checks up to date; BOS does not change this. MedlinePlus
Plan procedures with experienced dermatologic surgeons if cosmetic treatment is desired. JAMA Network
Use medications exactly as labeled; many people with BOS need none. OUP Academic
Re-evaluate new or changing lesions—do not assume all bumps are BOS. MedlinePlus
When to see a doctor
See a dermatologist or primary care clinician if you notice new, rapidly growing, painful, or ulcerated skin lesions; persistent joint or bone pain; or if an imaging report raises concern about bone spots you already know are osteopoikilosis. Seek care before procedures if you take blood thinners or have medical conditions that affect healing. Consider genetics referral if multiple family members are affected or for preconception counseling. MedlinePlus+1
What to eat—and what to avoid
Eat: a balanced diet rich in whole foods (fruits, vegetables, lean proteins, legumes, whole grains) with adequate protein and vitamin C to support routine skin repair, and ensure vitamin D sufficiency if deficient. Avoid/limit: excessive alcohol (impairs wound healing), smoking (worsens skin outcomes), and high-dose unproven supplements around procedures unless your clinician advises them. There is no BOS-specific diet; these are general skin-health principles. JAMA Network+1
FAQs
Is BOS dangerous?
Usually no. It is benign for most people, and bone strength is not impaired by osteopoikilosis. OUP AcademicIs BOS cancer or a sign of cancer?
No. The bone “spots” can be mistaken for metastases if doctors are unfamiliar, but OPK is benign. PubMedWhat gene is involved?
Most cases involve loss-of-function in LEMD3, affecting TGF-β/BMP signaling. NatureWill my children get it?
BOS is autosomal dominant; each child has ~50% chance of inheriting the variant, but severity varies. DermNet®Do I need treatment?
Often no. Many choose simple reassurance; others consider cosmetic procedures if lesions bother them. OUP AcademicWhat doctor should I see?
A dermatologist for skin, and genetics for counseling; orthopedics only if there are significant symptoms. MedlinePlusCan creams make lesions disappear?
No proven topical therapy removes BOS nevi; moisturizers can improve comfort and cosmesis. JAAD Case ReportsDo lasers work?
Lasers can smooth texture or remodel dermis; results vary and are adjunctive. Discuss expectations and risks. PubMed+1Is there a pill for BOS?
No. Medicines are for symptoms (e.g., pain) or post-procedure care. OUP AcademicCan BOS cause pain?
Most people are pain-free; a minority report aches. Simple measures and occasional analgesics usually suffice. Cleveland ClinicDoes OPK weaken bone?
No—OPK does not reduce bone strength or transform into malignancy. OUP AcademicHow is BOS confirmed?
By clinical findings ± biopsy, characteristic imaging, and sometimes LEMD3 testing. NCBI+1Could it be something else?
Doctors may consider tuberous sclerosis, neurofibromas, pseudoxanthoma elasticum, and others; pathology helps differentiate. JAAD Case ReportsWill lesions spread?
Lesions often appear in childhood/adolescence and then stabilize; big changes should be checked. MedlinePlusWhere can I read more?
