Cutaneous horn and Callosity of the ankle: A case report

Cutaneous horn is a horn-like keratotic lesion, which commonly occurs on the head and face, over a wide range of benign or malignant skin lesions. Callosity is a hyperkeratotic plaque produced by intermittent or continuous pressure on the skin. Lateral aspects of the ankles (Lateral malleoli) are frequently involved. We report a rare case of cutaneous horn developed on ankle callosity.
