Oncocytic carcinoid of the kidney positively detected by I-131 MIBG scintigraphy.

摘要

The occurrence of oncocytic carcinoids in the kidney is extremely rare. The present case involves intractable hypertension with high-blood adenocorticotropic hormone (ACTH) values. A tumor was observed in the right kidney, and an abnormal accumulation was identified in the mass from 1-131 metaiodobenzylguanidine scintigraphy. Surgery resulted in an initial diagnosis of oncocytoma. However, problem was finally diagnosed as the oncocytic carcinoid by supplemental pathologic examinations. Although oncocytomas are common renal tumors, if an oncocytoma is associated with hypertension or endocrine abnormalities, it is important to consider the possibility of oncocytic carcinoid and to perform additional pathologic examinations.
