ABSTRACT
Adrenal cortical carcinomas are rare neoplasms and the definitive diagnostic criteria are distant metastasis and / or local invasion. Due to advances in imaging techniques, adrenal cortical neoplasms are discovered earlier and are smaller, increasing the need for more accurate diagnosis and pathologic indicators of prognosis. A twelve year retrospective clinicopathologic analysis of 15 histopathologically proven cases of adrenocortical carcinomas was done. Clinical details including radiologic findings, endocrine manifestations and gross finding were analysed. Hematoxylin and eosin stained slides were reviewed. Emphasis was on application of Weiss criteria. All fifteen tumors fulfilled Weiss criteria of malignancy, ie. all 15 possessed 3 or more of these criteria of malignancy. Functional tumors showed a greater representation of mixed cell type. It was concluded that Weiss criteria is easy to apply and that a combined evaluation of clinical features, size, weight and microscopic appearance seems necessary for the diagnosis of adrenocortical carcinomas.
