Abstract

Aldosterone-producing adrenocortical carcinoma is a rare malignancy, which is usually diagnosed by histopathological examination of the excised tumor. In inoperable cases, aldosterone-producing ACC diagnosed by immunohistochemical staining of the metastatic tumor for Cytochrome P450 (CYP) 11β has not previously been reported and even in that case staining for adrenocortical-specific adrenal 4 binding protein/steroidogenic factor1 (Ad4BP/SF1) and steroidogenic enzymes has not been reported. We report the case of a 67-year-old Japanese woman with aldosterone-producing adrenocortical carcinoma. Laboratory findings showed severe hypopotassemia. Endocrinological examination revealed an increased plasma aldosterone concentration and suppressed plasma renin activity. Plasma dehydroepiandrosterone sulfate (DHEA-S) was elevated. Diurnal variation in serum cortisol was lost and administration of 1 mg and 8 mg dexamethasone did not suppress serum cortisol levels. From the 24-h urine collection sample, urine aldosterone and urine cortisol levels were greatly increased. Therefore, autonomous excess production was observed for the three adrenal cortex hormones. Abdominal computed tomography and magnetic resonance imaging showed a right adren...Continue Reading

Adrenocortical Carcinoma

Adrenocortical carcinoma (ACC) is a rare malignancy of the adrenal cortex, associated with a generally dismal prognosis owing to its aggressive behavior. Here are the latest discoveries pertaining to this disease.

Adrenocortical Carcinoma

Hepatocellular carcinoma is the most common type of primary liver cancer and frequently occurs in individuals with chronic liver diseases like cirrhosis. Here is the latest research.

Cancer Imaging

Imaging techniques, including CT and MR, have become essential to tumor detection, diagnosis, and monitoring. Here is the latest research on cancer imaging.
