Photoletter to the editor: Giant cutaneous horn associated with squamous cell carcinoma.
A 90-year-old patient presented with a large cutaneous horn (cornu cutaneum) of nine-year duration arising at her right cheek. The lesion was removed by surgery. Histology was reported as cornu cutaneum with a well-differentiated squamous cell carcinoma at its base. Cutaneous horn is morphological designation for protuberant mass of keratin that resembles the horn of an animal. Such lesions appear on sun-exposed skin areas like upper parts of the face and ears in elderly patients. Large cutaneous horns (> 1 cm) tend to be more commonly associated with squamous cell carcinoma compared to smaller cutaneous horns, particularly when present on the face.
