Abstract
Merkel cell carcinoma is an unusual cutaneous neoplasm of aggressive characteristics, classified within neuroendocrine carcinomas; clinically polymorphic and histologically similar to other skin tumors making it difficult for early diagnosis. Given its low incidence; the pathogenesis of this tumor, the recent description of a viral association and its treatment, are still matter of research; for this reason it is important to know its pathophysiology and clinical manifestations in order to perform a clear diagnostic approach in early stages, and treatment in accordance with the patient’s condition. We describe the case of an inmunosupressed patient with a Merkel cell carcinoma on face and scalp, recurrent and metastatic, with an evolution consistent to reports in the literature.
