An epidermoid cyst (epidermal inclusion cyst, infundibular cyst), is a benign growth commonly found on the skin of the face or neck, but can occur anywhere on the body. Epidermoid cysts result from the reproduction of epidermal cells within a confined space which creates a "cheesy” consistency and often a pungent odor! They may have no symptoms and are typically harmless, but people often seek removal because they don't like the appearance of these bumps or because the cyst has ruptured or become inflamed in the past. Rupture is associated with sudden redness, pain, swelling, and local heat, and can lead to abscess formation. A history of inflammation often increases scar tissue in the area, making the cyst more firmly adherent to the surrounding skin, and making it more difficult to remove. Surgical excision is curative, but the entire cyst sac and contents need to be removed to ensure the cyst won't grow back!
