[A case of non-functioning adrenocortical tumor]

A resected case of a non-functioning adrenocortical tumor is reported. The patient's chief complaint was fever and general fatigue. Computed tomography and ultrasonography revealed the suspected presence of a tumor on the right lobe of the liver, though a definite diagnosis of a right adrenal tumor was reached after hepatic angiography. An endocrinal examination, however, showed no abnormality. The tumor was dissected sharply from the right hepatic lobe and completely removed with a part of the diaphragm. It measured 10 x 12 x 18 cm and weighed 1,280 g. Hemorrhagic and necrotic changes were noted in the cut section, and a subsequent pathological examination revealed an adenocarcinoma of the adrenal cortex. An administration of 5-FU was given orally and the patient's progress has gone well without a recurrence or a metastasis for 4 years and a month since the surgery.
