Abstract
Introduction: The aim of this paper is to present a case of rare retroperitoneal tumor.
Material and Methods. A 72 year old man presented with six month history of abdominal girth, lumbar pain and occasional episodes of constipation was admitted in our clinic. A computed tomographic abdominal scan revealed a retroperitoneal solid mass.
Surgical exploration performed later displayed solid and well delimited mass throughout retroperitoneal space followed by excision of lesion and multiple drainages. Microscopic pathological examination was benign nerve sheath tumor.
Conclusion. These tumors are characteristically firm, smooth, and asymptomatic. They range in size from 1-2 mm to over 20 cm. Awareness of this indolent and rare condition is an important prerequisite for early diagnosis and appropriate treatment. Surgical excision can usually be accomplished by enucleating of the tumor without damage to the adjacent nerve.
