Mullerian tumors are extremely rare malignancies in the retroperitoneum. We report a case of a 46-year old woman who presented with an eight year history of lower abdominal mass. Ultrasonography (US) and computed tomography (CT) demonstrated a 15×10 cm cystic mass in the left lower retroperitoneum. As serial percutaneous needle aspiration cytology was negative for malignancy, she was observed f...

Introduction Necrotizing fasciitis (NF) is a devastating soft tissue disease causing fulminant clinical deterioration, and extension into the retroperitoneum has a high mortality rate. This disease process demands a strong clinical suspicion for early identification which must be coupled with frequent wide surgical debridements and intravenous antibiotics for improved outcomes. Various clinical...

INTRODUCTION The aim of this research was to create a laboratory instrument for the estimation of post-transplant lymphocele origin. It is based on the enzymatic activity of creatine kinase (CK) in the lymphocele content. MATERIAL AND METHODS A total of 120 lymph samples from different retroperitoneal regions were obtained from non-transplanted patients; equal numbers from the iliac region, r...

Dedifferentiated liposarcoma (DDL) with divergent dedifferentiation is uncommonly reported variable incidences. Liposarcomas, particularly those manifesting dedifferentiation, occur in the retroperitoneum. They grow into large size, present at very late stages, and can have a poor clinical outcome. Here we rare case of recurrent dedifferentiated dual heterologous differentiation osteosarcoma Ch...

BACKGROUND Germ cell tumors are tumors composed of tissues derived from more than one of the three germinal layers. They are more common in the testes and ovaries, but can present in many different regions in the midline, including the sacral region, retroperitoneum, mediastinum, and brain. Testicular germ cell tumors generally metastasize to the retroperitoneum, lungs, and brain; metastases to...

A 31-year-old Japanese man with chronic abdominal pain underwent laparoscopic surgery using both a single port and 2.4-mm needle forceps for a preoperatively diagnosed intestinal malrotation. Abdominal findings revealed a twisted mesenteric pedicle; it also revealed that the right-side colon was not fused to the retroperitoneum and that both the transverse colon and the mesocolon were adhered t...

Dumb bell shaped tumours have been reported infrequently in literature of which the usual ones being retroperitoneal tumours extending to the scrotum via the inguinal canal or extending through the femoral canal and presenting in the thigh. Cases of a thigh liposarcoma extending to the retroperitoneum are very rare. We could come across only publications in this regard 5. We report a patient wi...
