title: [A case of non-functioning adrenocortical adenoma associated with renal cell carcinoma].
abstract: Left renal and left adrenal masses were incidentally found by computerized tomography (CT) in a 56-year-old man who was admitted to our hospital for treatment of upper digestive tract hemorrhage. Apparently no clinical signs suggestive of Cushing's syndrome existed. The renal tumor was diagnosed as renal cell carcinoma based on the findings on enhanced CT. 131I-adosterol uptake in the examination of adrenal scintigraphy under dexamethasone suppression was definitely increased in the left adrenal gland, although hormonal examinations of serum and urine for adrenal functions were within the normal range. Plasma adrenocorticotropic hormone (ACTH) and serum cortisol were suppressed by administration of 2 mg dexamethasone for 2 days. The left kidney was radically removed by surgery together with the left adrenal gland. Histological diagnoses were left renal cell carcinoma and adrenocortical adenoma.
