A laparoscopic treatment of a suspicious adrenal mass revealing an unsual cause of adrenal incidentaloma

Abstract

Schwannomas are rare tumors, usually benign, originating from the Schwann sheath of the peripheral or cranial nerves. They ar e an extremely uncommon cause of adrenal incidentaloma. It is difficult to diagnose adrenal schwannoma preoperatively by imaging alone due of their aspect suspect on it. We report a case of adrenal mass discovered incidentally in a 41 years old patient who presented an atypical abdominal pain. Biological assessment was unremarkable, and imaging studies did not show strict imaging criteria for a typical adenoma. A surgical excision of the adrenal incidentaloma was decided. Histopathological examination and immunohistochemical staining of the excised specimen revealed a benign schwannoma.
