Abstract:
A keratin horn is a horn-like projection composed of dense keratotic material. It usually arises in sun-exposed areas of the body. It can be derived from a variety of underlying benign, premalignant, or malignant epidermal lesions. Risk factors associated with malignant change within a keratin horn include a wide base, male sex, and increasing age, in addition to an origin in a sun-exposed area. The mainstay of management is to obtain a biopsy from the base of the horn and subsequent excision if the histopathologic analysis suggests a malignancy. We report an extremely rare case of bilateral keratin horns arising from the tympanic membranes in a 64-year-old woman. To the best of our knowledge, this is the first report of its kind to be published in the English-language literature.
