摘要
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.
