ABSTRACT
The cutaneous horn is a conical neoplasm, exophytic and keratotic, so designated by the morphological similarity to the horn of an animal. It is a cutaneous manifestation rather than a real pathological diagnosis, although it has in association with a wide variety of underlying benign, premalignant and malignant diseases. Its initial diagnosis is clinical, however to rule out malignancy as a basic pathology it is always necessary to perform its surgical exeresis and histopathological study. The treatment consists in the complete resection of the lesion, followed by a histopathological study to determine the diagnosis. Sebaceous carcinoma, a malignant neoplasm derived from the adnexal epithelium of sebaceous glands, has been described as a rare etiology of cutaneous horn. Its diagnosis is difficult, since it lacks characteristic clinical elements and its histology may be similar to squamous cell or basal cell carcinoma, but important as it constitutes an aggressive neoplasia, with risk of local recurrence and metastasis. Next, we present the case of a 14-year-old adolescent with clinical diagnosis of cutaneous horn in the left ocular angle and histopathological diagnosis of cutaneous horn.
