Abstract

Retroperitoneal schwannoma is a rare occurrence, accounting for less than 2% of all retroperitoneal tumors 1 . Schwannoma is a tumour originating from Schwann cells which are found in the nerve sheath of peripheral nerves. They are generally benign. We found a retroperitoneal mass incidentally following investigation for renal stones in 59 years old male patient. After CT and MRI examinations we prefered open surgery and removed the mass which was in monoblock and with intact capsule. The histopathologic diagnosis was schwannoma. There were no complications, recurrence or metastasis within 18 months follow up.

Abstract

Retroperitoneal tümörler içinde schwannoma görülme olasılığı %2 den azdır 1 . Schwannomalar periferal sinirlerin kılıfında bulunan Schwann hücrelerinden kaynaklanırlar. Genelde benign karekterdedirler. Biz de, böbrek taşı nedeniyle takip ettiğimiz 59 yaşındaki erkek hastamızın sol böbreğinin üst ön yüzünde kitleyi insidental olarak tespit ettik. CT MRI incelemeleri sonrası tümöral kitle tanısıyla açık cerrahi uygulamaya karar verdik. Tek parça halinde kapsülü intakt olarak çıkartılan kitlenin patoloji incelemesi sonucu schwannoma olduğu anlaşıldı. Komplikasyon görülmeyen hastanın 18 aylık takibi sonunda nüks ya da metastaz görülmedi.
