Epidermal Cysts

Epidermal cysts, sometimes called sebaceous cysts, are common benign skin growths that can develop anywhere on the body. These cysts are often harmless but can cause discomfort or cosmetic concerns. In this comprehensive guide, we will break down the various aspects of epidermal cysts, providing you with simple, easy-to-understand explanations.

Types of Epidermal Cysts:

1. Epidermoid Cysts: These cysts form when the skin’s surface cells (epidermis) get trapped beneath the skin. They typically contain keratin, a protein found in hair and nails.
2. Pilar Cysts: Also known as trichilemmal cysts, these cysts originate from hair follicles and contain a different type of keratin. They often appear on the scalp.

Causes of Epidermal Cysts:

1. Hair Follicle Blockage: When a hair follicle becomes blocked, it can lead to the formation of an epidermal cyst.
2. Skin Trauma: Injuries to the skin, such as cuts or punctures, can sometimes result in the development of cysts.
3. Hormonal Changes: Fluctuations in hormone levels, especially during puberty, can contribute to cyst formation.
4. Genetics: A family history of cysts may increase the likelihood of developing them.
5. Excessive Sun Exposure: Sun damage to the skin can be a contributing factor.
6. Skin Infections: Infections can lead to inflammation, which may trigger cyst formation.
7. Blockage of Oil Glands: When oil glands in the skin become blocked, cysts can develop.
8. Foreign Bodies: Occasionally, objects like splinters or tattoo ink can become trapped under the skin, causing cysts to form.
9. Certain Medical Conditions: Conditions like Gardner’s syndrome and basal cell nevus syndrome can predispose individuals to epidermal cysts.
10. Use of Steroids: Long-term use of steroids can sometimes lead to cyst development.
11. Acne and Acne Medications: Acne-prone individuals and some acne medications may be more susceptible to cysts.
12. Old Age: Cysts are more common in older adults.
13. Excessive Sweating: Sweating excessively can contribute to the formation of cysts, particularly in skin folds.
14. Scarring: Scar tissue can sometimes trap skin cells, leading to cysts.
15. Certain Skin Conditions: Skin conditions like acne and folliculitis can increase the risk of cysts.
16. Sex Hormones: Changes in sex hormone levels, such as during pregnancy, can influence cyst development.
17. Poor Hygiene: Inadequate skincare and cleanliness can contribute to cyst formation.
18. Ingrown Hairs: Ingrown hairs can create a conducive environment for cysts to develop.
19. Obesity: Excess body weight can lead to skin friction and increase the risk of cysts in skin folds.
20. Nutritional Deficiencies: Lack of essential nutrients may affect skin health and contribute to cysts.

Symptoms of Epidermal Cysts:

1. Visible Lump: The most common symptom is a painless, round or oval lump beneath the skin’s surface.
2. Skin Discoloration: The cyst may cause the skin above it to appear reddish or whitish.
3. Swelling: Cysts can lead to localized swelling in the affected area.
4. Pain or Tenderness: Some cysts may become painful if they become infected or inflamed.
5. Thick, Yellowish Fluid: When a cyst ruptures, it may release a thick, foul-smelling, yellowish substance.
6. Skin Irregularities: The skin over the cyst may appear stretched, shiny, or have a central pore or punctum.
7. Infection: Infected cysts can cause redness, warmth, and increased pain.
8. Pressure Sensation: You may feel pressure or discomfort if the cyst grows larger.
9. Drainage: Occasionally, cysts can spontaneously drain fluid, relieving pressure temporarily.
10. Itching: Some people experience itching around the cyst.
11. Inflammation: Inflamed cysts may appear redder and feel tender to the touch.
12. Skin Breakdown: Severe cysts can lead to skin ulceration or breakdown.
13. Foul Odor: Infected cysts may emit an unpleasant odor.
14. Secondary Infections: Scratching or picking at a cyst can introduce bacteria and cause infections.
15. Hair Growth: Cysts on the scalp may cause hair to grow from the central pore.
16. Difficulty Moving: Large cysts in areas with frequent movement, like joints, may limit mobility.
17. Cosmetic Concerns: Cysts in visible areas can cause cosmetic worries.
18. Pressure on Nerves: In some cases, cysts may press on nearby nerves, causing discomfort.
19. Inflammatory Response: The body’s immune response can lead to localized inflammation.
20. Recurrence: After treatment, some cysts may return if the entire cyst wall is not removed.

Diagnostic Tests for Epidermal Cysts:

1. Physical Examination: Doctors can often diagnose cysts by inspecting and palpating the affected area.
2. Ultrasound: An ultrasound can provide detailed images of the cyst’s structure.
3. CT Scan: A CT scan may be used for larger or deep-seated cysts.
4. MRI: Magnetic resonance imaging can offer a clear view of the cyst’s location and size.
5. Biopsy: In some cases, a small sample of tissue may be removed for examination.
6. Needle Aspiration: A needle may be used to withdraw fluid from the cyst for analysis.
7. Blood Tests: Blood tests can help rule out underlying medical conditions.
8. Dermoscopy: A specialized magnifying tool can assist in examining skin lesions.
9. Histopathology: Microscopic examination of tissue samples can confirm the diagnosis.
10. Cystogram: In rare cases, a contrast dye may be used to visualize the cyst’s internal structure.
11. Fine Needle Aspiration Cytology (FNAC): A thin needle is used to collect cells from the cyst for analysis.
12. X-ray: An X-ray may be done if there is suspicion of bone involvement.
13. Skin Biopsy: For unclear cases, a skin biopsy can provide a definitive diagnosis.
14. Cultures: Fluid drained from an infected cyst can be cultured to identify the responsible bacteria.
15. Punch Biopsy: A small tool is used to remove a piece of the cyst for examination.
16. Video Dermoscopy: A specialized camera can magnify and capture images of the cyst.
17. Tissue Staining: Staining can highlight specific features of the cyst on a microscopic level.
18. Genetic Testing: In cases of recurrent cysts, genetic testing may be considered.
19. Tissue Culture: Culturing tissue can help identify any unusual growth patterns.
20. Physical Examination Changes Over Time: Monitoring the cyst’s appearance and symptoms over time can aid diagnosis.

Treatments for Epidermal Cysts:

1. Watchful Waiting: Small, asymptomatic cysts may not require immediate treatment but should be monitored.
2. Warm Compresses: Applying warm, moist compresses can help reduce inflammation and encourage drainage.
3. Incision and Drainage (I&D): A doctor may make a small incision and drain the cyst’s contents.
4. Cyst Removal: Surgical excision is the most common method to remove the cyst and its cyst wall.
5. Laser Therapy: Laser treatment can be used for smaller cysts and may reduce scarring.
6. Corticosteroid Injections: In some cases, steroids may be injected to reduce inflammation.
7. Antibiotics: If an infection is present, antibiotics may be prescribed.
8. Topical Antibiotics: For mild infections, topical antibiotic creams can be used.
9. Intralesional Injections: Medications can be injected into the cyst to reduce its size.
10. Cryotherapy: Freezing the cyst with liquid nitrogen may be an option for some.
11. Electrocautery: Heat can be used to destroy the cyst’s contents and close the wound.
12. Minimal Excision Technique: A smaller incision is made to minimize scarring.
13. Radiosurgery: High-frequency electrical currents are used to cut and remove the cyst.
14. Laser Ablation: Laser energy is employed to vaporize the cyst’s contents.
15. Carbon Dioxide (CO2) Laser: This laser is used to excise the cyst and seal the wound.
16. Hyfrecator: A low-power electric current can remove the cyst’s contents.
17. Punch Biopsy Excision: A punch tool is used to excise the cyst.
