Leiomyosarcomas of the ovarian vein are very rare. Four cases have been reported in the English language clinical literature. We present a case of leiomyosarcomas where the use of multi-detector CT had a substantial role in the establishment of the preoperative diagnosis. The radiological images as well as intraoperative features are illustrated. We also discuss the radiological findings of the...

Metastatic spermatocytic seminoma is an extremely rare disease with only one documented case in literature. We present another patient with metastatic disease confirmed by histological work-up after laparoscopic retroperitoneal lymph node dissection (L-RPLND).

Retroperitoneal fibrosis is characterized by development of extensive fibrosis, leading to entrapment and obstruction of retroperitoneal structures, notably the ureters. In most cases, the etiology is unknown. It is occasionally associated with autoimmune diseases. Response to corticosteroids and immunosuppressive therapy suggest it is probably immunologically mediated. The symptoms and signs a...

A huge retroperitoneal tumor with a right orbital mass was detected and proved to be an extragonadal nonseminomatous germ cell tumor on biopsy. BEP chemotherapy caused some regression in orbital mass however no change in retroperitoneal tumor size as well as serum tumor marker levels occurred. Herein, we present a rarely seen entity of extragonadal retroperitoneal nonseminomatous germ cell tumo...

OBJECTIVE To develop and describe a laparoscopic retroperitoneal access technique, investigate working space establishment, and describe the surgical anatomy in the retroperitoneal space as an initial step for clinical application of retroperitoneal laparoscopy in dogs. STUDY DESIGN Cadaveric and experimental study. ANIMALS Cadaveric (n=8) and healthy (n=6) adult dogs. METHODS The retrope...

We successfully performed 6 LESS radical nephrectomy via the retroperitoneal approach (RLESS) using the Alexis wound retractor as a single access with conventional laparoscopic instruments. The results demonstrated that our RLESS technique of radical nephrectomy is a safe and feasible procedure for management of localized renal cancer.

Damage control is a surgical strategy for severely compromised trauma patients based on speed control of life-threatening injuries that aims to rapidly resuscitate patients in an intensive care unit (ICU). We report on the use of such therapeutic strategy in a patient affected by a retroperitoneal sarcoma concomitant to a horseshoe kidney, a relatively rare anatomical malformation.

A case of huge enhancing solid mass in the abdomen observed in 30 years old gentleman is reported. Patient was worked up and managed conservatively outside valley with the provisional diagnosis of an appendicular lump. When examined, he was found to have huge intra abdominal mass. Interestingly when the genitalia was examined he was found to have underdeveloped empty scrotum without testes in i...

Ectopic endometrial tissues are rarely observed on the serosal surfaces of bowel and laparotomy incisions, in the lungs, bones and in the urinary tract. Recto-sigmoid junction is the most common site of extra-genital endometriosis, with less frequent sites being the rectovaginal septum, small intestine, cecum and appendix. Endometriotic cyst in a retroperitoneal location mimicking a retroperito...

Retroperitoneal fibrosis is a rare disease, typically with an insidious clinical course. It is thought that this disease process is perhaps an exaggerated reaction to an inciting inflammatory event. In this study, a case of retroperitoneal fibrosis is reported, in which the patient presented with typical symptoms of retroperitoneal fibrosis, along with some atypical vasculitic symptomatology. R...
