Epidermal inclusion cysts are benign cutaneous growths filled with keratin and cellular debris. They become inflamed when the cystic sac ruptures and its contents cause a foreign body-like reaction. Cysts do not typically indicate an infectious process though they may sometimes feature a secondary infection. Treatment is not necessary; however, uncomplicated epidermal inclusion cysts may be removed by surgical excision. Surgical excision is the most definitive treatment and minimizes the risk of recurrence. Inflamed epidermal inclusion cysts should first be treated with a corticosteroid injection to reduce inflammation before performing a surgical excision.
