Giant Retroperitoneal Teratoma in an Adult Presenting with Abdominal Mass: A Case Report and Literature Review

Abstract

A teratoma is a true neoplasm that comprises tissues that are either distinct from the initial site of origin or histologically heterogeneous and represent several embryonic germ layers. Here we present a case report of a 24-years-old female patient who presented with chief complaints of swelling in the right upper abdomen for 4 months. Per abdomen, examination revealed a lump of around 20 cm in size in the right hypochondriac region extending to the Lumbar and umbilical region. Contrast-enhanced computed tomography abdomen revealed a large, well-encapsulated, heterogeneous mass lesion of approximate size 30.3x18.4x2 in the right retroperitoneal/suprarenal region. The lesions show fat components with few incomplete septations and few specks of calcification. No evidence of solid component or hemorrhage within the lesion. The patient was taken up for exploratory laparotomy and a tumor was found in the retroperitoneum and was excised with due care. Histopathological examination features were suggestive of Dermoid Cyst. The post-operative stay was uneventful.
