Sebaceous cyst
Alternate Names : Epidermal cyst, Keratin cyst, Epidermoid cyst
Symptoms & Signs
The main symptom is usually a small, non-painful lump beneath the skin. However, if it becomes infected, you may have redness, tenderness, or increased temperature of the skin over the area. Grayish-white, cheesy, foul-smelling material may drain from the cyst.
Diagnosis & Tests
In most cases, your doctor can diagnose this type of cyst by simply examining your skin. Occasionally, a biopsy may be needed to rule out other conditions.
