Adrenocortical carcinoma: diagnosis by fine needle aspiration cytology

Two cases of adrenal cortical carcinoma are described, wherein the diagnosis was established by fine needle aspiration cytology (FNAC). FNAC is increasingly being accepted as a means of diagnosis of adrenal cortical carcinomas. In yester years the diagnosis was established largely on post-operative histopathology. Adrenal cortical carcinomas are rare and account for less than 0.05% of all malignant neoplasms. Adrenal gland has become frequent target of needle biopsies with the availability of sensitive imaging techniques and better localization. Currently, needle biopsy is the only non-surgical means of obtaining a diagnosis in patient with adrenal mass. We present two cases of adrenal cortical carcinoma diagnosed on fine needle aspiration cytology (FNAC).
