We report an extremely rare case of a 69-year-old man having a retroperitoneal carcinoid tumor associated with multiple endocrine neoplasia (MEN) type 1. The patient whose son and daughter were previously diagnosed with MEN type 1 was admitted to the Department of Endocrinology at our hospital for evaluation of this disorder. Computed tomography (CT) and ultrasonography revealed a parathyroid and retroperitoneal tumor (43mm×34mm). The patient did not consent to surgical management of the tumor; however three years later, a follow-up CT revealed tumor enlargement (55mm×50mm). We were unable to rule out a malignancy, and subsequently resected the tumor. A pathological diagnosis of retroperitoneal carcinoid was made. No local recurrence or metastasis have been observed for 21 months.
