Atypical thymic carcinoid and malignant somatostatinoma in type I multiple endocrine neoplasia syndrome

Thymic carcinoid and malignant somatostatinoma are both rare, and their concurrent presence in multiple endocrine neoplasia type 1 (MEN-1) has never been reported in the English literature to date. We present a patient with thymic carcinoid and malignant somatostatinoma in association with MEN-1. The patient eventually died of pulmonary aspergillosis and respiratory failure. Autopsy showed a 16 × 10 × 8-cm thymic carcinoid tumor, parathyroid and adrenal gland hyperplasia, and malignant somatostatinoma of the pancreas with a metastatic tumor over the splenic hilum.
