title: [Oncocytic adrenocortical neoplasms].
abstract: Oncocytic neoplasms of the adrenal gland are rare, as described in literature. Only 27 cases have been reported up to now in world literature. Here we describe our experience. In this report we discuss the clinicopathologic and immunohistochemical findings of three oncocytic tumors of the adrenal cortex. Two tumors were found during examination of the patients for other reasons. These tumors were hormonally inactive. One tumor manifested by the virilization of the patient. Immunohistochemical examination demonstrated in all tumors focal positivity with antibodies to neuron-specific enolase and synaptophysin and mostly focally weak positivity for cytokeratins. Very low mitotic activity was found in two tumors. Criteria for evaluation of biological character of this type of tumors are not established.
