Trichilemmomas are benign epidermal neoplasms that may serve as an indicator of underlying malignancy. Trichilemmomas appear, largely on the head and neck, as exophytic, small, hyperkeratotic papules (Figure 15.1). There is no particular gender predilection and they usually arise during the second decade. When occurring as isolated lesions, these tumors are invariably benign and are of no clinical significance.
