Carcinoma de células de Merkel

Abstract

The Merkel cell carcinoma (MCC) is an infrequent neuroendocrine neoplasm with a high specific mortality rate. Its diagnosis is supported by the clinic, histopathology and immunohistochemistry. A 83 year old female patient who has had a tumor on her left cheek for 45 days is reported. With a presumptive keratoacanthoma diagnosis, exeresis biopsy was performed. Histopathology and immunohistochemistry studies suggest MCC. No invasion was found and surgical resection followed. Due to the patient's age and facial flaccidness, double M-Plasty was chosen for its simplicity, reliability and minimal probability of postsurgical complications.
