Retroperitoneal Liposarcoma Presenting as Right Inguinal Hernia - A Rare Entity

Abstract

Background: The purpose of this case report is to highlight a rare entity of retroperitoneal liposarcoma presenting as inguinal hernia. Difficulty in preoperative diagnosis, surgical management & outcome are discussed. Pitfalls in diagnosis and management are also highlighted. Introduction: Inguinal hernia is a common condition with the majority of patients presenting in the surgical outpatient department. Retroperitoneal sarcoma projecting through the groin is very rare. In literature only 10 cases have been published over the last 30 years. Case Presentation: Middle age person presented in OPD with complaint of right Inguinal swelling for 1 & ½ years. He was diagnosed with right inguinal hernia. On exploration there was a huge mass communicating to retroperitoneum. Laparotomy was done & mass excised. On histopathology it was revealed to be liposarcoma. Conclusion: Sometime history, clinical examination and even investigations can be misleading but if inguinal hernia is large, growing slowly, non-reducible then retroperitoneal tumor must be ruled out carefully in differential diagnosis of hernia by extended preoperative workup.
