We report the case of a 39-year-old male with a right adrenal mass. Laboratory tests were normal and radiological exams revealed the adrenal tumor. Open surgical adrenalectomy was performed. The postoperative course was uneventful. Microscopy and immunohistochemistry revealed a cellular schwannoma. Adrenal schwannomas are rare tumors, very difficult to diagnose in preoperative evaluation. Surgical excision of the tumor, histological and immunohistochemical examination of the specimen provide a definitive diagnosis. Prognosis is generally very good. Recurrence rates are related to positive surgical margins.
