Abstract

Cutaneous horn is the clinical term for a circumscribed, conical, markedly hyperkeratotic lesion. We report a case of cutaneous horn occuring on the face in a 81 year old women. An about 1.2 X1.3 cm sized dark brownish conical horn was developed on her face 1 year before. Histopathologic findings showed marked hyperkeratosis, parakeratosis, and papillornatosis of the epidermis, and some cells of straturn mslpighii showed pleornorphism and nuclesr atypis. This case was considered to be cutaneous horn arising from actinic keratosis, and we performed minimal local excision.
