Epidermal cyst
Clinical Classification Guidelines
Medical Intelligence & Overview
An epidermal cyst, also known as an epidermoid cyst, is a common benign growth that occurs under the skin. These cysts are typically slow-growing, painless, and often appear on areas like the face, neck, or trunk. While generally harmless, they can sometimes cause discomfort or become infected. This guide provides an overview of epidermal cysts to help you understand their causes, symptoms, diagnosis, and treatment options.
Causes & Symptoms
Clinical Causes: Blocked hair follicles or skin pores leading to cyst formation Skin trauma or injury that damages hair follicles or skin layers Cell proliferation within the epidermis, causing a cyst to form Genetic factors that predispose individuals to cyst development Certain skin conditions or infections that can contribute to cyst formation
Key Symptoms: Small, round, or dome-shaped bump beneath the skin Smooth or slightly raised skin lesion Possible central opening or punctum on the cyst surface Cyst may be soft or firm to the touch In some cases, the cyst may become red, swollen, or painful if infected Discharge of a thick, foul-smelling material if the cyst ruptures or becomes infected
Diagnostic & Treatment
Diagnosis Path: Diagnosis of an epidermal cyst is typically made through a physical examination by a healthcare provider. The doctor will examine the cyst and may ask about recent changes or symptoms. In some cases, the healthcare provider might perform a small biopsy or extract a sample of the cyst's contents for laboratory analysis to confirm the diagnosis and rule out other conditions. Imaging tests are rarely needed unless the cyst is deep or difficult to evaluate.
Treatment Protocols: Observation: Small, asymptomatic cysts can often be monitored without immediate treatment. Surgical removal: The preferred treatment involves excising the entire cyst and its lining to prevent recurrence. This procedure is usually performed under local anesthesia. Drainage: If the cyst is inflamed or infected, an incision and drainage may be performed to release pus and reduce discomfort, followed by antibiotics if infection is present. Medication: Antibiotics may be prescribed if the cyst becomes infected, but they do not eliminate the cyst itself. Prevention: Good skin hygiene and avoiding skin trauma can help reduce the risk of cyst formation. Avoid squeezing or trying to pop the cyst, as this can lead to infection or scarring.
