case_images: Clinical findings: clinical examination revealed a right frontal exophytic nodule 2 cm long, firm, mobile, painless and not ulcerated (Figure 1). Then, it revealed an ulcerated papule on the right auricle (Figure 2), and small patches of dry, crusted skin on the face (Figure 1).

case_images: Anatomopathological and immunohistochemical examinations were in favour of a frontal trichilemmal carcinoma, selected in view of a trichilemmal proliferation made of endophytic cells centred by clear cells (HEX10) (Figure 4), a very marked mitotic activity (HEX40) (Figure 5), an absence of BEREP4 expression and a loss of CD 34 expression (Figure 6).
