Epidermal Cyst Definition and Symptoms
Epidermal cysts are small, hard lumps which form underneath the skin. They most often form on the face, head, neck, back and genitals and can range in size from a quarter of an inch to two inches in diameter. The presence of the cysts are the only symptom. Epidermal cysts are harmless for the most part and very rarely can become cancerous.
