High levels of alpha-1-fetoprotein are usually associated with nonseminoma carcinoma of the testis or hepatocellular carcinoma of the liver. We describe a male patient with extrahepatic hepatocellular carcinoma who presented with a large retroperitoneal mass and extremely high alpha-1-fetoprotein levels. The importance of taking an adequate biopsy specimen cannot be emphasised enough since both...

BACKGROUND Currently no prospective randomized trial has measured the efficacy of radiation therapy for resected retroperitoneal sarcomas (RPS). Our objective was to determine the effect of radiation therapy on disease-specific and overall survival between propensity score-matched surgically resected RPS patients using the Surveillance, Epidemiology, and End Results (SEER) database. PATIENTS ...

Background Q fever is an infection caused by Coxiella burnetii, an intracellular organism. Acute infection is most often a benign and asymptomatic process; however, some individuals may go on to develop subacute and persistent localized symptomatic Q fever. As such, the clinical and histopathologic findings of Q fever are widely variable and may be missed if clinical suspicion is not high. Ca...

Retroperitoneal haematomas in obstetrics are uncommon. The causes and pathogenesis of retroperitoneal haematomas lack clarity and the aim of this review is to recognise retroperitoneal haematomas as a separate entity from commonly seen vaginal and pelvic haematomas. It is time to raise awareness among obstetricians to recognise retroperitoneal haematomas as an important cause of maternal morbid...

operative anaesthetic care, we can obtain a better definition of the tumour mass preoperatively and accept the challenge of demanding surgical procedures. Retroperitoneal lipomata are uncommon and have an indolent presentation. Lipomas occurring in this site are a different proposition than those in other sites and require meticulous pre-operative evaluation and an exacting surgical approach if...

CONTEXT Retroperitoneal enteric duplication cysts (EDC) are rare lesions and its presentation during adulthood is a diagnostic challenge for clinicians. The diagnosis of this condition is established following histopathological analysis, which often requires surgical intervention. CASE REPORT We report a case of a retroperitoneal enteric duplication cysts, presenting as a cystic lesion of the...

We present the case of a 70-year-old man with a giant right-sided retroperitoneal pseudocyst, confirmed histologically after resection to be benign with appearances dissimilar to pancreatic and adrenal tissue. The cyst was noted incidentally on table at the time of laparoscopic surgery. Retroperitoneal pseudocysts most commonly arise from the pancreas and adrenal glands occurring as a result of...

BACKGROUND Castleman's disease is a rare and poorly understood disease entity that may resemble more common conditions and represents a clinical challenge to the treating surgeon. CASE PRESENTATION In this report, we describe a case of a 61-year-old Caucasian woman with a symptomatic retroperitoneal mass. The specimen obtained from her resection contained a protuberant encapsulated mass, exhi...

We reported two cases of retroperitoneal hematoma in patients who received a combination of anticoagulant therapy and 5-fluorouracil (5-FU). We should be aware of the possible interaction of this combination therapy and monitor prothrombin time (PT) prolongation. CT is useful for evaluation of the disease.
