BACKGROUND Currently, the standard treatment for renal pelvis carcinoma is radical nephroureterectomy with bladder cuff excision. To describe the feasibility of retroperitoneal laparoscopic partial nephrectomy with segmental renal artery clamping for cancer of renal pelvis, we report this special case for the first time. CASE PRESENTATION A 67-year-old woman received this operation. Preoperat...

BACKGROUND Inflammatory myofibroblastic tumor (IMT) is a neoplasm of unknown etiology occurring at various sites. By definition, it is composed of spindle cells (myofibroblasts) with variable inflammatory component, hence the name is IMT. CASE PRESENTATION The present case is of a 46 years old woman presented with a history of flank pain, abdominal mass and intermittent hematuria for last 6 m...

Primary retroperitoneal mucinous cystadenomas are uncommon tumors whose incidence in the pediatric population is very low. We present the case report of a 17-year-old female with a primary retroperitoneal mucinous cystadenoma, borderline type, and describe the successful laparoscopic resection of the mass. 2014 The Authors.

Introduction: Meningiomas and retroperitoneal sarcomas are two distinct rare tumors, with an incidence of 2 and 0.4 cases per 100,000 respectively. Case Report: We report the case of a 39 year old woman with a history of intracranial meningioma who was found two months later to have a large retroperitoneal sarcoma on CT scan after presenting to the emergency department complaining of abdominal ...

Background: Abdominal tumors are still a diagnostic problem in children. This study was conducted to assess the presentation and types of childhood intra abdominal tumors in children in Shiraz. Materials and Methods: Participants of this historical cohort study consisted of 298 children aged between 1.5 months to 15 years old who were diagnosed with abdominal mass between March 2003 and March 2...

Malignant rhabdoid tumour is a very rare neoplasm with high lethality rate. Its neoplastic cells present rhabdomyoblastic features, although those must be differentiated from epithelioid sarcoma, melanoma, and rhabdomyosarcoma. Therefore, this case report of 21-year-old man who presented Malignantrhabdoid in the head pancreas. Patient was submitted to partial pancreatomy gastrectomy block, sple...

Primary retroperitoneal mucinous tumor (PRMT) of low malignant potential (border line) is an uncommon neoplasm with fewer than 50 reported cases. Uncertain diagnostic imaging results make diagnosis of its origin difficult, preoperatively. Later treatment planning and prognosis would be affected by exact diagnosis of the tumor origin. This study presents a case of Persian woman with diagnostic, ...

Solitary fibrous tumor (SFT) is a rare stromal neoplasm and usually occurs in the thoracic cavity. We here report a case of retroperitoneal SFT with prominent calcification. A 64-year-old man presented with an incidentally detected retroperitoneal mass in the right upper abdomen. Imaging tests indicated an integrally calcified mass. The lesion was observed for 2 years and laparoscopically resec...

Leiomyosarcoma (LMS) of inferior vena cava (IVC) is a rare neoplasm affecting approximately 1/100,000 people. The prognosis is poor and potential curative intent occurs through challenging operations, such as vena cava resection, occasionally multivisceral when required, and vascular reconstruction. There are few retrospective series regarding this retroperitoneal neoplasm, and the aim of the p...
