[Horton's disease: facial manifestations].

Facial manifestations due to giant cell arteritis are analysed about 102 cases. The whole facial vascular territories are involved, so we have many manifestations. Diagnosis depends on artery biopsy with Doppler aid.

[Metatypical carcinoma. Apropos of 4 cases].

The authors describe the anatomopathological, clinical and evolutive characteristics of the metatypical carcinoma, based on four cases and on the existing literature. Evolution of these tumors, with a maxillo-facial preferential location, is usually longer than for other cutaneous carcinomas. Cases presented in this article illustrate the severity of such lesions, whose treatment requires extensive amputations and rather unusual reconstruction procedures.
