The syndrome of ectopic production of ACTH by non-pituitary neoplasm occurs with various types of tumors. ACTH-producing thymic carcinoid tumor is rare and has not been reported in Korea. We have experienced a 36-year-old male patient with ACTH-producing thymic carcinoid tumor, presenting symptoms of generalized weakness and weight gain. Clinical presentation, radiologic and hormonal evaluation, and pathologic examination were compatible with ACTH-producing thymic carcinoid tumor. The immunohistochemical staining of the thymic carcinoid tumor showed positivity for ACTH. Primary and metastatic tumor and both adrenal glands were resected. Radiation therapy and chemotherapy were performed. The prognosis of this patient is thought to be poor.
Key Words: Ectopic, ACTH, Thymic carcinoid tumor
