Trichilemmal horn or trichilemmal keratosis is a benign neoplasm, that occurs more frequently in females and in the age group over 50 years old. Clinically, it presents as a cutaneous horn and histologically shows trichilemmal keratinization at the base of the lesion.As an uncommon pathology, in this case report, we will present the case of a young man (14 years old), presenting a keratotic lesion on the forehead for eight months, which revealed the diagnosis of trichilemmal horn after lesion exeresis and anatomopathological analysis.

Cutaneous horn is a conical, circumscribed, dense hyperkeratotic protrusion from skin with epithelial cornification. It is also known by the Latin name ‘Cornu cutaneum’. This rare medical entity resembles animal horn but histological disparity is present between both. They are more commonly present in sun exposed sites or areas that are prone for actinic radiation, burns and hence frequently seen in forearm and upper part of face. Only few cases have been reported with cutaneous horns in unusual sites. Cutaneous horns occurring in oral cavity or perioral regions are extremely rare. The significance of knowing about this dead keratinous cutaneous horn is that it may occur as a part of or in association with a wide range of underlying pathologies, either malignant, premalignant or benign. Majority are due to benign pathologies. We report an unusual presentation of cutaneous horn in left oral commissure of a 45-year-old gentleman which is an extremely rare perioral location for such an ailment.

Cutaneous horn is a protuberance constituted by compact keratinous material, with a hard consistence similar to a horn, which occurs more frequently in photoexposed areas. The authors describe a case of cutaneous horn on the glans considered a rare location. Verrucous carcinoma was the histopathological diagnosis of the base of the horn and lichen sclerosis, the precursor lesion.
