[Clinical diagnosis of basal cell epitheliomas of the face (author's transl)]

Basal cell epitheliomas occur most frequently on the face and have very variable appearances: cicatricial and flat, ulcerous, even deep, and nodular, sclerodermiform, or pigmented. A very positive diagnostic finding is small epitheliomatous pearls often grouped together at the periphery of the lesion. Though the effects of these lesions are purely local, as metastases never occur, they frequently have a tendency to relapse.
