Cornu cutaneum or cutaneous horn is a rare clinical presentation resembling an animal horn. The lesion is often seen arising from sun-exposed skin surface. We report a case of Rhino-cutaneous horn which developed from the sun-protected surface of nasal vestibule. The broad based lesion was completely excised and microscopically proved to be non-malignant Introduction Cornu cutaneum or cutaneous horn is a relatively uncommon clinical entity consisting of a compacted hyperkeratosis over a hyperproliferative lesion and it resembles an animal horn1. The base of the lesion may be flat, nodular or crateriform. Cutaneous horn most often arises on the sun-exposed skin surface in elderly men, usually after fifth decade2. The lesion is found on scalp, face, pinna, eyelids, nose, neck, shoulders, hands and penis. The possibility of malignancy at the base of the lesion increases in men when compared with the age-matched women. Various histological variants have been documented at the base of the keratin mound therefore histopathological confirmation is often necessary to rule out benign, premalignant and malignant changes.
