L72.8
Other follicular cysts of the skin and subcutaneous tissue
Clinical Classification Guidelines
Medical Intelligence & Overview
Other follicular cysts of the skin and subcutaneous tissue (ICD-10 code L72.8) are benign, non-cancerous lumps that form beneath the skin. These cysts are characterized by their origin from hair follicles or skin structures involved in hair production. Typically, they are filled with keratin, a protein that forms skin, hair, and nails. Although usually harmless, they can sometimes cause discomfort or cosmetic concerns depending on their size and location. Recognizing the nature of these cysts can help guide appropriate management and reduce unnecessary worry.
Causes & Symptoms
Clinical Causes: Blocked hair follicles leading to cyst formation Occlusion of the follicular infundibulum, allowing keratin buildup Infections or inflammation that obstruct hair follicle ducts Genetic predisposition influencing skin structure and follicle functioning Trauma or skin injury that damages hair follicles Hormonal changes affecting skin and hair follicle activity
Key Symptoms: Round or oval lumps beneath the skin that are usually slow-growing Lumps that are firm, elastic, or soft to touch Possible redness or swelling if inflamed Discomfort or tenderness, especially if infected or inflamed A visible or palpable cyst that does not usually cause symptoms
Diagnostic & Treatment
Diagnosis Path: Diagnosis is primarily based on a physical examination by a healthcare professional, who will assess the cyst's appearance, location, and texture. They may ask about any symptoms like pain or changes in the cyst. In some cases, imaging studies such as ultrasound may be used to evaluate the cyst's characteristics more precisely. If needed, a small sample may be taken for laboratory analysis (biopsy) to confirm the diagnosis or rule out other skin conditions.
Treatment Protocols: Management options depend on the size, location, and symptoms of the cyst. Common approaches include: - **Observation:** Many cysts do not require treatment unless they cause discomfort or cosmetic concern. - **Surgical removal:** For symptomatic or bothersome cysts, a healthcare provider may perform a minor procedure to extract the cyst manually or excise it completely. - **Drainage:** In cases of inflammation or infection, draining the cyst may provide relief, though this does not prevent recurrence. - **Medication:** Topical or oral antibiotics might be prescribed if infection or inflammation is present. - **Monitoring:** Regular follow-up to observe changes in cyst size or symptoms. It's important to avoid attempting to puncture or remove a cyst at home, as this can increase the risk of infection or scarring.
