Presentation

History

Cutaneous horns usually are asymptomatic. Because of their excessive height, they can be traumatized. This may result in inflammation at the base with resulting pain. Rapid growth is common in presentation.

Physical Examination

Cutaneous horns can occur anywhere on the body. However, the more typical distribution is on sun-exposed areas, particularly the face, pinna, nose, forearms, and dorsal hands. Thirty percent of cases have been seen to arise on the scalp and upper face. [2, 32, 33] They are most commonly a solitary lesion.

It is a hyperkeratotic papule with the height greater than one-half the width of the base. Usually, a cutaneous horn is several millimeters long, but they can grow to be quite large, up to 25 cm in some cases, and 36 cm diameter in historic cases. [1, 34]
