Multiple primary neoplasms are not common, those containing renal
neurilemoma are even more rare. Our study involves the diagnosis and treatment of a female patient with
multiple primary neoplasms with renal
neurilemoma. She was previously diagnosed with left ovarian
dermoid cyst, right posterior mediastinal
neurilemmoma, left forearm
neurilemmoma, and
papillary thyroid carcinoma, underwent operation treatment. Physical examination reveals a left renal mass with a left adrenal
tumor a month before, and underwent retroperitoneal laparoscopic left adrenal nodule resection and left partial
nephrectomy. Operation was successful, without conversions to open. Artery occlusion time was 18 min, and blood loss was 20 mL. Post operation pathologic result shows a left renal cellular
leiomyoma neurilemmoma with focal cystic change, and
tumor diameter was about 3 cm. Immunohistochemistry reports S-100 (+), Ki-67 (15%+), and short-term follow-up without recurrence. In our case of study, even though the
tumors were heterochronism, they were both treated with surgical resection. Renal
neurilemoma is benign. Laparoscopic partial
nephrectomy is not only minimally invasive, fast in recovery, but most importantly preserves renal tissue to the largest extent. It can prevent preoperative pathological uncertainty, which often undergoes radical
nephrectomy.
