RENAL SCHWANNOMA MASQUERADING AS MALIGNANCY

Schwannomas are tumours of the nerve sheath that are usually benign. The tumour is commonly found in the head, neck, and extremities.Involvement of the kidney by Schwannomas is extremely uncommon . A preoperative diagnosis is difficult therefore, renal schwannomas are often diagnosed incidentally during pathologic examination. The renal hilum can be a site of renal schwannoma development because parasympathetic nerve fibers of the kidney accompany the renal artery, which enters into the renal hilum. However, many renal schwannomas are located in the renal parenchyma and mimic a renal cell carcinoma rather than a transitional cell carcinoma. Herein, we report a rare case of a renal schwannoma with renal stone disease that mimics a renal cell carcinoma and that was treated by laparoscopic nephrectomy.
