To the Editor.—
Cornu cutaneum or the cutaneous horn is a peculiar type of benign neoplasm showing horn-like projection on the skin. Although the cutaneous horn may develop over a normal skin, these more often develop over some preexisting skin conditions like warts, keratoses, nevi, trauma, burns, lupus vulgaris, and even on an epithelioma.1 In the normal process of keratinization, the dead keratin is being gradually cast off as dust. If this keratin continues to stick on, the result is a horn which represents marked cohesiveness of the keratin.2,3 Since the horn represents an erroneous epithelial growth, it may sometimes be complicated with malignancy. We came across an interesting case of penile horn supervening over an excised wart which is recorded below.
