Epithelial Inclusion Cysts

An epithelial inclusion cyst, also known as an epidermoid cyst, is a benign, slow‑growing bump that forms beneath the skin when epidermal cells become trapped in the dermis?. These cells continue to produce keratin, leading to a sac filled with a soft, cheese‑like material. Epithelial inclusion cysts commonly occur on areas with hair follicles—such as the face, neck, and trunk—but can appear anywhere on the body. Although typically painless, they may become tender, red, or infected if inflamed or traumatized DermNet®.

An epithelial inclusion cyst is a closed sac lined by stratified squamous epithelium (the same kind of cells that make up your outer skin or the lining of your eye). Inside, it contains layers of keratin, lipids, and cellular debris. Unlike other cysts that may arise from glandular tissue or fluid accumulation, inclusion cysts form when epithelial cells are “implanted” beneath the surface—often due to trauma? or developmental anomalies. They grow slowly and generally feel smooth, round, and movable on palpation. Histopathologically, the wall shows multiple layers of flat, scale‑like cells, sometimes with small pockets of mucus or inflammatory cells if irritation is present.

Types of Epithelial Inclusion Cysts

1. Congenital? Inclusion Cyst
   Present at birth, these arise from developmental sequestration of surface cells during embryonic growth. They most often appear along lines of embryonic fusion (e.g., near the eyebrow or at the lateral canthus of the eye). Because they form before birth, they usually enlarge slowly and may not be noticed until later in childhood or adulthood.

2. Acquired (Secondary) Inclusion Cyst
   These develop after injury, surgery, or chronic? inflammation?. Any event that pushes surface epithelium under the skin—such as a surgical incision, a puncture wound, or persistent rubbing—can seed cells deeper, leading to cyst formation over weeks to months.

3. Pilar (Trichilemmal) Cyst
   A subtype that arises from hair‑follicle outer root sheath cells, most commonly on the scalp. While technically an inclusion cyst, it tends to have a firmer feel and thicker wall than a typical epidermoid cyst, and it often runs in families.

4. Orbital Epithelial Inclusion Cyst
   Occurring within the eye socket, these can result from eye‑related surgery (e.g., enucleation or fracture? repair) or trauma that implants conjunctival or skin epithelium into the orbit. They may enlarge slowly and, if large enough, push the eye forward (proptosis) or limit eye movement.

5. Conjunctival Inclusion Cyst
   Found on the surface of the eye’s white part (the sclera?) under the clear membrane (the conjunctiva?), these smooth, fluid‑filled sacs often follow pterygium removal, chalazion surgery, or chemical injury. They can irritate the eye surface and cause chronic watering or foreign‑body sensation.

6. Implantation Cyst of the Eyelid
   When eyelid skin is cut or traumatized—during blepharoplasty, chalazion excision, or blunt trauma—epidermal cells can implant into the tarsal plate (the firm tissue of the eyelid), leading to a cyst that bumps on the inner eyelid surface and rubs on the eye with each blink.

Causes of Epithelial Inclusion Cyst

1. Surgical Trauma – Incisions made during procedures like chalazion removal, pterygium excision, or blepharoplasty can trap surface cells beneath tissue closures, leading to cyst growth over weeks.

2. Blunt Injury – A forceful blow to the eyelid or orbit may drive skin or conjunctival cells into deeper layers, where they multiply.

3. Congenital Cell Sequestration – During facial or ocular development, surface cells may become “pinched off” beneath the skin without any external trauma, forming congenital cysts.

4. Chronic Inflammation – Long‑standing eyelid inflammation (e.g., blepharitis) can damage epithelial integrity and encourage cyst formation in areas of repeated irritation.

5. Chemical Burns – Strong acids or alkalis can destroy tissue boundaries, pushing epithelial fragments inward and triggering cyst development during healing.

6. Radiation Therapy? – Radiation to the head and neck region may alter epithelial behavior and healing, occasionally resulting in inclusion cysts.

7. Intraocular Surgery – Procedures like cataract removal or vitrectomy can accidentally implant conjunctival cells into the orbit or deeper tissues.

8. Orbital Fracture Repair – Using implants or grafts in the orbit may introduce epithelial cells into the bony socket.

9. Persistent Eye‑Rubbing – Habitual rubbing (e.g., in allergic conjunctivitis) can abrade the surface and force cells beneath the epithelium.

10. Stevens‑Johnson Syndrome? – Severe? mucocutaneous reactions can disrupt epithelial barriers, with healing sometimes entrapping cells.

11. Chemical Conjunctivitis – Repeated exposure to irritants (e.g., chlorine, cosmetics) may damage conjunctival surfaces and allow cell implantation.

12. Human Papillomavirus (HPV) – Certain HPV strains can induce epithelial proliferation and abnormal healing, raising the risk of cyst formation.

13. Genetic? Predisposition – A family history? of epidermoid or pilar cysts suggests inherited? tendencies for cystic epithelial growth.

14. Chronic Pterygium Recurrence? – Multiple removals of pterygium (a fleshy growth on the eye) raise the chance of inadvertent epithelial implantation.

15. Improper Wound Care – Failing to clean or close a wound thoroughly after trauma can leave epithelial fragments behind, which later organize into cysts.

Symptoms of Epithelial Inclusion Cyst

1. Visible Lump
   The most common sign is a small, round bump on the eyelid margin, under the conjunctiva, or inside the orbit—usually flesh‑colored or slightly translucent.

2. Painless Swelling?
   Early cysts tend to be soft and without pain?; patients often first notice a new bump without discomfort.

3. Foreign‑Body Sensation
   Especially with conjunctival or eyelid cysts, the feeling of something in the eye may persist, leading to constant blinking or rubbing.

4. Redness
   Surrounding tissue can become mildly inflamed if the cyst erodes the overlying surface or leaks keratin.

5. Watery Eyes (Epiphora)
   A cyst pressing on the lacrimal drainage system can block tears, causing overflow onto the cheek.

6. Blurry Vision
   Large orbital cysts or surface cysts extending onto the cornea? may distort the eye’s optical surface.

7. Photophobia?
   Light sensitivity? may occur if the cyst rubs the cornea or induces localized? inflammation.

8. Eyelid Droop (Ptosis)
   A heavy cyst on the upper eyelid can weigh it down, leading to a droopy eyelid that partially covers vision.

9. Restricted Eye Movement
   Deep orbital cysts may impinge on the muscles that move the eye, limiting gaze in certain directions.

10. Recurrent? Inflammation
    Cysts that chronically leak keratin can provoke repeated redness, pain, and swelling episodes.

Diagnostic Tests

Physical Examination

1. Visual Inspection
   The clinician examines the eye and eyelid under normal light to note cyst size, color, surface changes, and any discharge.

2. Slit‑Lamp Biomicroscopy
   Using a magnified, focused beam of light, the ophthalmologist assesses the cyst’s depth, translucency, and relationship to adjacent tissues.

3. Palpation
   Gentle fingertip pressure on the eyelid or orbital rim tests the cyst’s consistency (fluid‑filled vs. firm) and mobility.

4. Fluorescein Staining
   A drop of fluorescein dye highlights any corneal abrasions or epithelial defects caused by rubbing against the cyst.

5. Lid Eversion
   Flipping the eyelid allows direct viewing of inner‑surface cysts that might be hidden when the eyelid is down.

Manual Tests

6. Digital Compression Test
   Applying gentle pressure over the cyst checks for fluid movement, fluctuation, or firmness, helping differentiate cysts from solid masses.

7. Needle Aspiration (Office-Based)
   With a fine needle, a sample of cyst contents can sometimes be obtained to confirm keratinous material and reduce size temporarily.

8. Squeeze Test
   Firm but gentle squeeze over the cyst evaluates whether pressure causes leakage of contents onto adjacent mucosa or skin.

Laboratory and Pathological Tests

9. Fine‑Needle Aspiration Cytology (FNAC)
   Under topical anesthesia, cells from the cyst lining are withdrawn and examined microscopically to confirm epithelial origin.

10. Histopathological Biopsy?
    Complete or partial cyst removal provides tissue that, when stained and viewed under a microscope, shows the characteristic squamous epithelium lining and keratin core.

11. Gram Stain and Culture
    If the cyst appears inflamed or infected, its contents can be cultured to identify bacterial? growth and guide antibiotic? therapy.

12. Immunohistochemistry
    In rare cases, markers for epithelial cell proliferation (e.g., Ki‑67) help distinguish benign cysts from neoplastic lesions.

Electrodiagnostic Tests

13. Visual Evoked Potential (VEP)
    For large orbital cysts affecting the optic nerve?, VEP measures electrical activity in the brain in response to visual stimuli to detect optic pathway compression.

14. Electroretinogram (ERG)
    To assess retinal function if a cyst presses on the globe, the ERG records electrical responses of retinal cells to flashes of light.

15. Electromyography (EMG) of Extraocular Muscles
    When eye movement is restricted, EMG can evaluate muscle electrical activity to distinguish neural from mechanical causes.

Imaging Tests

16. Ultrasound B‑Scan
    High‑frequency sound waves map the cyst’s size, depth, and internal echoes—clear cyst fluid appears echo‑free, while keratin yields low‑level echoes.

17. Ultrasound Biomicroscopy (UBM)
    This high‑resolution anterior segment imaging visualizes superficial cysts under the conjunctiva or within the eyelid’s tarsus.

18. Computed Tomography (CT) Scan
    CT provides cross‑sectional images of the orbit, showing any calcification, bone involvement, or deep extension of a cyst.

19. Magnetic Resonance Imaging (MRI)
    MRI offers superior soft‑tissue contrast, delineating cyst walls, surrounding muscles, nerves, and any associated inflammation.

20. Optical Coherence Tomography (OCT)
    For conjunctival or corneal‑adjacent cysts, OCT uses light waves to generate detailed, cross‑sectional images of the anterior ocular surface and underlying tissues.
