Diagnosis and open excision of concurrent pelvic schwannoma and chromophobe renal cell carcinoma.

Schwannomas are tumors that commonly affect the nerve sheath, typically involving peripheral and cranial nerves. These tumors are rarely found within the pelvis and retroperitoneum. To date, there have been no documented cases of concurrent chromophobe renal cell carcinoma and pelvic schwannoma. We present the case of a 57-year-old female with a right renal mass significant for chromophobe renal cell carcinoma and a left pelvic mass found to be a schwannoma. This case highlights the importance of adding schwannoma to the differential when considering a pelvic mass in the setting of renal cell carcinoma.
