Hemoperitoneum in peritoneal dialysis patients is a known but infrequent complication. Hemoperitoneum is more frequent in women because of its association with a variety of gynecologic presentations such as reflux menstruation, ovulation, endometrial tissue implants within the peritoneal cavity (endometriosis), and bleeding follicular cysts.

Paragangliomas are extra-adrenal tumors of the autonomic nervous system and may be found within the skull base, neck, chest, and abdomen. When presenting within the abdominal cavity, they may arise as a primary retroperitoneal neoplasm and can mimic vascular malformations or other conditions related to specific retroperitoneal organs such as the pancreas, kidneys, or adrenals. Retroperitoneal p...

BACKGROUND Retroperitoneal cystadenocarcinomas are rare lesions, the majority of cases presented as one-patient reports. METHODS We present two cases of retroperitoneal cystadenocarcinoma, both in women of reproductive age: one with aggressive behavior, and the remaining case, with a more indolent clinical evolution. RESULTS One case presented as pelvic tumor, was treated with surgical rese...

We report a case of retroperitoneal schwannoma mimicking lymph node metastasis. A 32-year-old man presented with an intrascrotal mass, and underwent radical orchiectomy. Histological examination revealed a typical seminoma of the testis. Systemic work-up for staging demonstrated a retroperitoneal mass, which was located in the supra-hilar inter-aortocaval region. Under the diagnosis of retroper...

Retroperitoneal schwannomas are rare tumors and a correct pre-operative diagnosis is often not possible. They are usually identified incidentally via cross-sectional imaging. Diagnosis is based on histopathologic examination and immunohistochemistry. A 57-year-old man with a retroperitoneal schwannoma, as an unusual localisation, is presented.

PURPOSE Retroperitoneal iliac procedures can enable successful endovascular repair of abdominal aortic aneurysm (AAA) in patients who otherwise would not be anatomically eligible. The purpose of this study was to determine perioperative outcome with adjunctive retroperitoneal procedures compared with standard bilateral femoral exposure. METHODS Between August 1997 and November 2002, 164 patie...
