Other follicular cysts of the skin and subcutaneous tissue
ICD10CM code
Name of the Condition
- Other Follicular Cysts of the Skin and Subcutaneous Tissue
- Also referred to as non-specific epidermoid cysts or sebaceous cysts, though not technically sebaceous.
Summary
- Follicular cysts are non-cancerous growths found just beneath the skin. They are often filled with keratin and can appear anywhere on the body but are commonly located on the face, neck, or trunk.
Causes
- These cysts typically form when hair follicles or skin glands are blocked, leading to a buildup of keratin. They can also develop from trauma or certain skin conditions.
Risk Factors
- Risk factors include acne, oily skin, and a history of cysts. Having a genetic predisposition or certain genetic disorders like Gardner syndrome may also increase risk.
Symptoms
- Common symptoms include a small, round bump under the skin that may have a blackhead at the center. The cyst is usually painless but can become red and tender if infected or inflamed.
Diagnosis
- Diagnosis is usually made through a physical examination. In some cases, a biopsy or imaging tests like ultrasound may be used to confirm the diagnosis.
Treatment Options
- Treatment may not be necessary if the cyst is not bothersome. Options include surgical removal, draining, or steroid injections to reduce swelling. Antibiotics may be prescribed if the cyst is infected.
Prognosis and Follow-Up
- Prognosis is generally good, as these cysts are benign. They may recur after removal. Regular follow-up ensures any changes in size or symptoms are monitored.
Complications
- Potential complications include infection, rupture, or significant discomfort. Rarely, untreated cysts may lead to scarring.
Lifestyle & Prevention
- Good skincare and avoiding skin trauma can help prevent cysts. Maintaining acne treatments may reduce their occurrence.
When to Seek Professional Help
- Seek medical attention if the cyst becomes painful, red, swollen, or shows signs of infection. Rapid growth or changes in appearance also warrant evaluation.
