Carcinoid tumors are rare neoplasms with an estimated incidence of 1 to 2 cases per 100,000 inhabitants. The malignant carcinoid syndrome, characterized by flushing, diarrhea, abdominal pain and, less frequently, pellagra, bronchospasm and valvular disease, occurs in less than 10% of patients. Nevertheless, in advanced stages of the disease, the incidence is about 40 to 50%. Retrospective studies and descriptive case series have shown that cutaneous involvement is relatively common but has rarely been reported. We present a case of carcinoid syndrome diagnosed with basis on skin findings on clinical examination.
