Malignant Trichilemmal Cyst, though rare, is a condition that affects the hair follicles. It can be challenging to understand, so we’ve created this simplified guide to help you learn about it. In plain English, we’ll cover its types, causes, symptoms, diagnostic tests, treatments, and drugs used for management.
Types of Malignant Trichilemmal Cyst:
- Single Malignant Trichilemmal Cyst: Occurs as a solitary cyst.
- Multiple Malignant Trichilemmal Cysts: Develops as multiple cysts on the scalp or skin.
Causes of Malignant Trichilemmal Cyst
- Genetic Predisposition: It can run in families.
- Aging: More common in older individuals.
- Sun Exposure: Prolonged sun exposure may play a role.
- Radiation Exposure: History of radiation therapy.
- Skin Trauma: Repeated injuries to the skin.
- Hair Follicle Abnormalities: Issues with hair follicle development.
- Hormonal Changes: Hormonal imbalances can contribute.
- Immune System Weakness: A weakened immune system may increase the risk.
- Gender: Slightly more common in women.
- Skin Inflammation: Chronic skin inflammation can be a factor.
- Previous Skin Lesions: Prior benign trichilemmal cysts.
- Chemical Exposure: Exposure to certain chemicals.
- Smoking: Smoking may increase the risk.
- Skin Infections: Chronic skin infections.
- Obesity: Higher BMI can be a factor.
- Diabetes: Some cases are associated with diabetes.
- Skin Conditions: Conditions like hidradenitis suppurativa.
- Medications: Certain medications may be linked.
- Environmental Factors: Exposure to environmental toxins.
- Immunosuppressive Medications: Use of immunosuppressive drugs.
Symptoms of Malignant Trichilemmal Cyst
- Scalp Lump: A painless lump on the scalp.
- Skin Nodule: A firm, raised nodule on the skin.
- Slow Growth: Cysts typically grow slowly.
- Size Increase: Gradual increase in cyst size.
- Skin Redness: Skin around the cyst may become red.
- Ulceration: In some cases, the cyst may break open.
- Bleeding: Cysts can bleed if injured.
- Foul Odor: An unpleasant smell may develop.
- Hair Loss: Hair loss over the cyst area.
- Pain or Discomfort: Discomfort may occur if cysts grow large.
- Skin Swelling: Swelling around the cyst.
- Skin Color Change: Skin color may change over the cyst.
- Infection: Secondary infection is possible.
- Scarring: Scarring can happen after cyst rupture.
- Itching: Itchy sensation in the cyst area.
- Pus Discharge: Pus can drain from the cyst.
- Tenderness: Cysts may become tender to touch.
- Skin Crusts: Formation of crusts on the cyst.
- Enlarged Lymph Nodes: Rarely, nearby lymph nodes may swell.
- Rarely, Metastasis: In severe cases, it can spread to other parts of the body.
Diagnostic Tests
- Clinical Examination: A doctor examines the cyst’s appearance.
- Biopsy: A small tissue sample is taken for analysis.
- Imaging (Ultrasound): Ultrasound helps visualize cyst characteristics.
- CT Scan: CT scans provide detailed images for evaluation.
- MRI: MRI can reveal cyst features and depth.
- Dermoscopy: A dermatoscope helps examine skin features.
- Blood Tests: To check for underlying conditions.
- Fine Needle Aspiration: A thin needle collects cyst fluid for analysis.
- X-ray: X-rays assess the cyst’s relationship to bones.
- Lymph Node Biopsy: For assessing lymph node involvement.
- PET Scan: Detects potential metastasis.
- Genetic Testing: To identify genetic predisposition.
- Histopathology: Microscopic examination of cyst tissue.
- Immunohistochemistry: Evaluates specific protein markers.
- Cultures: To check for bacterial or fungal infection.
- Cytology: Examines cells from cyst fluid.
- Molecular Testing: Assessing genetic mutations.
- Immunocytochemistry: Detects specific cell proteins.
- Tumor Marker Tests: Identifies specific markers.
- Bioluminescence Imaging: For tracking tumor growth in research.
Treatments for Malignant Trichilemmal Cyst
- Surgical Excision: Complete removal of the cyst.
- Mohs Surgery: Microscopic removal to minimize scarring.
- Radiation Therapy: For aggressive or inoperable cases.
- Chemotherapy: In advanced metastatic cases.
- Cryotherapy: Freezing the cyst with liquid nitrogen.
- Laser Therapy: Laser can vaporize cyst tissue.
- Electrosurgery: Electrical currents destroy the cyst.
- Intralesional Injection: Medication injected into the cyst.
- Topical Medications: Creams or ointments for localized treatment.
- Antibiotics: If there’s a secondary infection.
- Pain Management: Medications to relieve discomfort.
- Wound Care: Proper wound care after surgery.
- Scar Management: Minimizing post-surgery scars.
- Radiation therapy: Targeted radiation for unresectable cysts.
- Chemotherapy: For advanced or metastatic cases.
- Immunotherapy: Boosting the immune system’s response.
- Targeted Therapies: Specific drugs targeting cancer cells.
- Palliative Care: Focusing on symptom relief in advanced stages.
- Clinical Trials: Participation in research studies.
- Skin Grafting: Replacing excised tissue with healthy skin.
- Plastic Surgery: Cosmetic repair after cyst removal.
- Hair Transplantation: For hair loss correction.
- Drainage: Removal of cyst fluid.
- Laser Resurfacing: Improving skin texture and appearance.
- Radiosurgery: Precise radiation for small cysts.
- Skin Flap Reconstruction: Complex repair procedures.
- Vacuum-Assisted Closure: Enhances wound healing.
- Photodynamic Therapy: Light-based treatment.
- Electrochemotherapy: Combining electrical and drug therapy.
- Watchful Waiting: In cases of slow-growing, benign cysts.
