Abstract

Cutaneous horn (cornu cutaneum) is a circumscribed, conical, and hyperkeratotic epidermis projected from the skin surface. Cutaneous horn is described in domestic animals with unknown etiology in some of them. In this report, this lesion was observed on the apex of the ear in a female Pakistani goat. The size of the cutaneous horn was 12 cm length. It was removed under local anesthesia and fixed in 10% neutral buffered formalin. Histopathologic examination showed well-differentiated keratinocytes without atypical keratinocytes. Thick dermal collagenous bundles were observed in the horn base. Mononuclear cell inflammation was observed around the vessels of the dermis in the base of lesion.
