Trichoepithelioma is a benign neoplasm with differentiation toward hair structure formation.1 In most cases, multiple lesions develop, and the face is the most common site. The condition appears in adolescence and is transmitted as an autosomal-dominant trait. The solitary form of the disease, on the other hand, is not hereditary. It occurs more frequently in adults, and in most cases the lesion is no more than 1.0 cm in diameter. To our knowledge, the largest lesion, which measured 8.0 cm and weighed 250 g, was described by Chernobilsky.2
