Keratin Cysts

Keratin cysts, also known as epidermoid cysts, are common skin growths that can appear anywhere on the body. They usually form when a small piece of skin becomes trapped beneath the surface, causing a buildup of keratin, a protein found in the skin, hair, and nails. In this article, we will provide clear and concise information about keratin cysts, including their types, causes, symptoms, diagnostic tests, treatments, and relevant drugs.

Types of Keratin Cysts:

Keratin cysts can vary in size and appearance, but they typically fall into two main types:

1. Epidermoid Cysts: These cysts are filled with keratin and appear as small, round bumps on the skin’s surface. They are usually white or yellowish in color.
2. Pilar Cysts: Pilar cysts are similar to epidermoid cysts but tend to be firmer and are often found on the scalp. They can be pinkish or flesh-colored.

Causes of Keratin Cysts:

1. Skin Trauma: Injuries or trauma to the skin can sometimes lead to the development of keratin cysts.
2. Blocked Hair Follicles: When hair follicles become blocked, they can form cysts.
3. Genetic Predisposition: Some individuals may be genetically predisposed to developing these cysts.
4. Hormonal Changes: Fluctuations in hormones, such as during pregnancy, can contribute to cyst formation.
5. Excessive Sun Exposure: Prolonged exposure to the sun may increase the risk of developing these cysts.
6. Skin Conditions: Certain skin conditions, like acne, can make the skin more prone to cyst formation.
7. Aging: Cysts may become more common as people age.
8. Excessive Sweating: Sweating can contribute to the development of cysts, especially in areas prone to friction.
9. Poor Skin Hygiene: Inadequate cleansing and skincare routines can lead to cysts.
10. Ingrown Hairs: When hairs grow inward instead of outward, cysts can form around them.
11. Folliculitis: An infection or inflammation of hair follicles can trigger cyst development.
12. Excessive Oil Production: Overactive oil glands can play a role in cyst formation.
13. Exposure to Irritants: Contact with irritants or chemicals may contribute to cyst development.
14. Previous Cyst Removal: In some cases, cysts can return after removal.
15. Friction and Rubbing: Areas of the skin subject to constant rubbing or friction may develop cysts.
16. Smoking: Smoking can affect the skin’s health and increase the risk of cyst formation.
17. Excessive Makeup Use: Prolonged use of makeup products may clog pores and lead to cysts.
18. Certain Medications: Some medications may be associated with cyst development as a side effect.
19. High Humidity: Living in a humid environment can contribute to skin issues, including cysts.
20. Stress: Chronic stress can negatively impact skin health, potentially leading to cysts.

Symptoms of Keratin Cysts:

1. Visible Bumps: The most noticeable symptom is the appearance of small, raised bumps on the skin’s surface.
2. Painless: Keratin cysts are usually painless unless they become infected or inflamed.
3. Slow Growth: Cysts tend to grow slowly over time.
4. Smooth Surface: The skin over the cyst is typically smooth and may be stretched.
5. Whitish or Yellowish Color: The cyst’s content is often a white or yellowish, cheese-like substance.
6. Occasional Itching: Some people may experience mild itching around the cyst.
7. Inflammation: If a cyst becomes infected, it can become red, swollen, and painful.
8. Discharge: Infected cysts may ooze a foul-smelling, pus-like discharge.
9. Tenderness: Infected cysts can be tender to the touch.
10. Increased Size: Cysts can gradually grow larger over time.
11. Pressure Sensation: Some individuals report feeling a sensation of pressure beneath the cyst.
12. Skin Redness: Inflammation can cause the skin over the cyst to turn red.
13. Painful Swelling: Infected cysts may cause painful swelling in the affected area.
14. Thicker or Firmer Texture: Pilar cysts, in particular, may feel harder than epidermoid cysts.
15. Scarring: Repeated cysts or improper removal can lead to scarring.
16. Skin Discoloration: In some cases, the skin around the cyst may become discolored.
17. Hair Loss: Pilar cysts on the scalp may cause hair loss in the affected area.
18. Sensitivity to Touch: The cyst and the skin around it may be sensitive to touch.
19. Warmth: Infected cysts can feel warm to the touch due to inflammation.
20. Foul Odor: Infected cysts may emit a foul odor due to the presence of pus.

Diagnostic Tests for Keratin Cysts:

1. Clinical Examination: A healthcare provider can often diagnose a keratin cyst through visual inspection and palpation.
2. Biopsy: In some cases, a small tissue sample may be taken for examination under a microscope to confirm the diagnosis.
3. Ultrasound: Ultrasonography can help determine the cyst’s size and location, especially if it’s deep within the skin.
4. CT Scan: A computed tomography (CT) scan may be ordered if the cyst’s location is uncertain or if there are concerns about nearby structures.
5. MRI: Magnetic resonance imaging (MRI) provides detailed images of the cyst and its surroundings.
6. Dermoscopy: A dermatoscope, a special magnifying device, can be used to examine the cyst’s characteristics.
7. Needle Aspiration: In some cases, a needle may be used to extract fluid or material from the cyst for analysis.
8. Blood Tests: Blood tests can help determine if there is an underlying infection.
9. Cultures: If the cyst appears infected, a culture may be taken to identify the responsible bacteria.
10. X-ray: An X-ray may be performed to rule out other potential causes of a lump.
11. Skin Scraping: Scraping the skin’s surface may help identify any underlying conditions contributing to cyst formation.
12. Punch Biopsy: A punch biopsy tool may be used to remove a small section of the cyst for examination.
13. Fine Needle Aspiration (FNA): FNA involves using a thin needle to withdraw cells or fluid from the cyst.
14. Histopathological Examination: Tissue removed during cyst removal surgery may be sent for histopathological analysis.
15. Cytology: Cells from the cyst’s contents can be examined under a microscope to confirm the diagnosis.
16. Cystoscopy: If the cyst is near a body cavity, such as the mouth or genital area, a flexible tube with a camera (cystoscope) may be used to visualize and diagnose it.
17. Allergy Testing: In cases of recurrent cysts, allergy testing may be recommended to identify potential triggers.
18. Skin Biopsy: A sample of the cyst or the surrounding skin may be biopsied to rule out other skin conditions.
19. Tzanck Smear: This test involves taking a sample from an opened cyst to examine the cells under a microscope.
20. Genetic Testing: For individuals with a family history of cysts, genetic testing may help identify predisposing factors.

Treatment Options for Keratin Cysts:

1. Observation: Many small, asymptomatic cysts can be left alone if they don’t cause discomfort or aesthetic concerns.
