Summary:Trichilemmal horn or trichilemmal keratosis is a benign neoplasm, that occurs more frequently in females and in the age group over 50 years old.

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.
