Subcostal transabdominal incision with midline extension is excellent for removal of large renal or adrenal tumors, or bilateral or retroperitoneal tumors. This incision is simple and gives a wide surgical field without involving the pleural cavity. No troublesome complications resulting from this approach have occurred.

Abstract 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...

•A large cervical neurilemmoma-like leiomyoma can simulate a retroperitoneal tumor.•They are extremely rare tumors that require adequate bleeding control.•Comprehensive anatomo-pathological study should be done to rule out malignancy.

OBJECTIVE: Laparoscopic radical nephrectomy (LRN) has been suggested as the standard care for cancer patients in T1-2 stage. However, whether this advanced technique is most indicated suitable renal tumors higher than T3a and N1 unclear, especially different regions countries, such difference between European Asia. METHODS: From 2013 to 2021, data of pathologically diagnosed cell carcinoma (RCC...

Tumors are rarely diagnosed in newborns. Natural history of such tumors, their type, and response to treatment differ from those seen in older children. The etiology is still unclear. In this paper, a retrospective study is presented of diagnostics and management of neonatal tumors from 2008 to 2012. Out of 518 neonatal admissions in that period, tumors were diagnosed in 15 patients (2.8%), in ...

mesenchymal tissue at any body site. They represented only 0.64 percent of all new cancers in United States in 2006. Ten to twenty percent of soft tissue sarcomas occur in the retroperitoneum. In a population-based series reported in the Surveillance, Epidemiology, and End Results (SEER) database, the average annual incidence of retroperitoneal sarcomas was approximately 2.7 cases per million p...

BACKGROUND There is little knowledge on retroperitoneal sarcoma, but there are many controversies. The objective of the current study was to define the common and distinctive features of primary and secondary retroperitoneal sarcomas in terms of presentation, prognostic and therapeutic approach to improve the current management of these tumors. Vascular involvement impact was assesed in the two...

Retroperitoneal leiomyoma is a rare benign smooth muscle tumor almost exclusively found in women and with histopathological features similar to uterine leiomyomas. The pathogenesis of retroperitoneal leiomyoma is unclear and next to nothing is known about the cytogenetics and molecular genetics of the tumor. We present here a retroperitoneal leiomyoma with a t(9;22)(q33;q12) as the sole karyoty...

The present study aimed at identifying the clinical, radiological and pathological characteristics of retroperitoneal paragangliomas, and determining the association between the tumor features and the prognosis of patients following surgery. A total of 34 patients with retroperitoneal paragangliomas, who underwent resection between November 1999 and December 2015, were included in the present r...

A 59-year-old white man was referred for evaluation of epigastric pain that was radiating to his back and a 5-kg weight loss over 6 months. A computed tomography (CT) scan revealed a heterogeneous low-attenuation tumor, measuring 5cm in size, adjacent to the celiac artery and the pancreatic body (●" Fig.1). Sectorial endoscopic ultrasound (GF-UCT140-AL5; Olympus America Inc., New York, USA), co...
