A cutaneous horn (corn cutaneum) is a dense, hyperkeratotic conical
projection of skin arising from an unusual cohesiveness of keratinized
material. Cutaneous horns most frequently occur in sites that are exposed to
actinic radiation or burns. Forearm, cartilaginous portion of the ear, legs, and
hands may also be affected. Cutaneous horns can occur in sun protected areas. Histologic
confirmation is necessary to rule out malignant changes. No clinical features
reliably distinguish between benign and
malignant lesions. This is a case report of a cutaneous horn over inguinal region.
