title: Rare synchronous primary large B-cell gastric lymphoma and huge retroperitoneal liposarcoma with inguinal hernia in chronic hepatitis B patient.
abstract: Multiple primary neoplasms with synchronous or metachronous presentation are rare, although the incidence has recently increased because of several factors. We present the case of a 53-year-old patient with chronic hepatitis B who presented with abdominal mass, mild abdominal pain, and inguinal hernia. Computed tomography imaging demonstrated diffuse thickening of the gastric antral wall, together with a huge heterogeneous abdominal mass with predominant fat attenuation with septa that showed mild enhancement on contrast-enhanced scans. Distal gastrectomy and wide resection of the retroperitoneal mass was performed. Pathology exam led to a diagnosis of diffuse large B-cell gastric lymphoma with retroperitoneal liposarcoma. This is a rare case of a primary gastric lymphoma with another primary (sarcomatous) malignancy occurring synchronously in same patient.
