Giant adrenal schwannoma - A case report and literature review.

We introduce a 39-year-old man with an exceedingly large adrenal schwannoma who visited our outpatient department with epigastric pain and a palpable mass in the left upper abdomen. Abdominal computed tomography revealed a giant cystic lesion measuring >25 cm. Laparotomy was performed for tumor excision and partial nephrectomy. Pathological examination confirmed adrenal schwannoma. The patient has been free of tumor recurrence for 10 months. The tumor size in this case is unprecedented in the English literature indexed in PubMed. Precise preoperative evaluation, delicate radical excision, and postoperative monitoring are essential for successful management of such tumors.
