[Histological, ultrastructural and clinical study of a malignant adrenal neoplasm producing minor mineralocorticoids].

The authors describe a case of an adrenal tumor of unusual dimensions with a benign histological appearance. After a short period diffuse metastases developed. The metastases should the features a poorly differentiated carcinoma. The size of the tumor appears to be a useful element of judgement in differential diagnosis between adenoma and carcinoma of the adrenal glands.
