• Rationale and Comments

    The overwhelming majority of red and swollen epidermal cysts are inflamed but not infected. It is important to confirm infection before treating these cysts with antibiotics. Appropriate treatments for inflamed epidermal cysts include incision and drainage or an injection of corticosteroid directly into the cyst.
