BACKGROUND: Laparoscopic resection of retroperitoneal mass is challenging because of its location close to major vessels and a limited range of laparoscopic instruments [1-3]. We report a case of a huge retroperitoneal paraganglioma that was successfully excised laparoscopically using maneuver of hanging IVC METHOD: A 67-year-old female had abdominal mass detected during routine check-up. She had no symptoms associated mass. Hematologic, biochemical investigations, and hormone tests reveal normal results...

A late-relapse germ cell tumor might contain malignant non-germ cell tumors, known as 'somatic-type malignancy (SM)'. The development of a secondary SM is rare, and this phenomenon remains poorly understood. Case 1 developed lung metastasis 13 years after chemotherapy followed by retroperitoneal lymph node dissection for stage IIA non-seminoma. The tumor increased in size after chemotherapy. The patient underwent a pneumonectomy. Pathology revealed an adenocarcinoma with immature teratoma. The patient has experienced no relapse for 9 years...

BACKGROUND Wunderlich's syndrome, or spontaneous non-traumatic retroperitoneal hemorrhage, can be a life-threatening event. Renal angiomyolipoma is a rare benign tumor that can occur sporadically, or in association with tuberous sclerosis. A case of spontaneous retroperitoneal hemorrhage in a patient with tuberous sclerosis and bilateral renal angiomyolipoma is presented. CASE REPORT A 33-year-old female Caucasian patient, with a known medical history of tuberous sclerosis, was admitted to hospital as an emergency, with right-sided abdominal pain...

BACKGROUND: Peri-operative radiation of retroperitoneal sarcomas (RPS) is an important component of multidisciplinary treatment. All retrospective series thus far included patients treated with older radiation therapy (RT) techniques including 2D and 3DRT. Intensity modulated radiation therapy (IMRT) allows for selective dose escalation while sparing adjacent organs. We therefore report the first series of patients with RPS treated solely with IMRT, surgery and chemotherapy. We hypothesized that IMRT would permit safe dose escalation and superior rates of local control (LC) in this high-risk patient population...

Inflammatory myofibroblastic tumor (IMT) is a peculiar low-grade neoplasm of spindle cell fibroblasts and myofibroblasts in an inflammatory background. The lung is the most common site of involvement. Here, we report a case of paraneoplastic pemphigus (PNP)-associated with an extensive retroperitoneal IMT. The patient had a favourable response following treatment with a low dose of systemic steroid, mycophenolate mofetil, and intravenous immunoglobulin (IVIG). He subsequently underwent surgery for resection of the tumor with nephrectomy and five courses of IVIG were administered after surgery due to a minor relapse...

Rhabdomyosarcoma (RMS) is a rare soft tissue sarcoma. The already documented data regarding RMS state that it is more prevalent in males than females and also that its occurrence is more in Caucasians than Asians. The current incidence of RMS is 4.5 cases/million, and thus, it is a very rare cancer. The undifferentiated type is the most aggressive one with a rare presentation in the retroperitoneum. Overall, this case emphasizes that consideration should be given to wide range of diagnosis and that frozen section is the gold standard for a confirmatory diagnosis, as the first biopsy showed benign cells within the tumor...

Purpose: Inflammatory myofibroblastic tumors (IMTs) are rare, benign lesions most often seen in the lung of young adults but can occur in children, in various sites. They mimic, clinically and radiologically, malignant tumors - especially sarcomas and lymphomas. The aim was to review the clinical, radiological, and pathological data of children with a diagnosis of IMT referred to our department. Materials and Methods: This retrospective study was conducted at the Department of Medical and Paediatric Oncology, Regional Cancer Centre, Sher-I-Kashmir Institute of Medical Sciences, Srinagar, Jammu and Kashmir, India from January 2014 to December 2015...

REVIEW
Mohammad Y Zaidi, Robert Canter, Kenneth Cardona
Crafting effective surveillance strategies for retroperitoneal soft tissue sarcomas is difficult given the scarcity of literature on this rare disease. In this article, we will summarize the most recent literature on natural history and recurrence patterns of RPS compiled from multi-institutional collaborative studies and centers with extended follow-up data, and based on this evidence, propose principles for histology-based post-operative surveillance protocols.

A 74-year-old postmenopausal woman visited our gynecology clinic complaining of a palpable abdominal mass. Physical and radiological evaluation indicated that the mass exhibited features of a left ovarian neoplasm showing heterogeneous enhancement. Surgical resection was performed to confirm this suspicion. During surgery, a mass was observed only in the left ovary with no invasive growth, but adhesions to the surrounding peritoneum were seen. Given the patient's age, large mass size, and accompanying uterine myoma and right ovarian cyst, total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed...

A 26-year-old Caucasian sailor, with no past medical history aside from headache for the last 1 week, was found dead in his cabin. The body was stored in a refrigerator on board and disembarked for autopsy 3 days later. Autopsy showed a large, nodular, necrotic and hemorrhagic retroperitoneal mass, and smaller hemorrhagic nodules in the brain, lungs, liver, and left kidney, with the brain being markedly edematous. Both testes were descended and normal. Histologically, the retroperitoneal mass showed a malignant mixed germ cell tumor comprising choriocarcinoma, embryonal carcinoma, and teratoma components...

BACKGROUND: Pediatric retroperitoneal tumors in the renal bed are often large and heterogeneous, and their diagnosis based on conventional imaging alone is not possible. More advanced imaging methods, such as diffusion-weighted (DW) MRI and the use of intravoxel incoherent motion (IVIM), have the potential to provide additional biomarkers that could facilitate their noninvasive diagnosis. PURPOSE: To assess the use of an IVIM model for diagnosis of childhood malignant abdominal tumors and discrimination of benign from malignant lesions...

We herein report a case of a retroperitoneal tumor of unknown origin that was diagnosed as a seminoma after tumor biopsy and was successfully treated with chemotherapy containing bleomycin, etoposide, and cisplatin(BEP). A 47-year old man visited our hospital with left abdominal pain. An endoscopic examination revealed an ulcer lesion on the third part of the duodenum. Abdominal CT scan revealed a retroperitoneal tumor invading the abdominal aorta with the tumor thrombus in the inferior vena cava(IVC). An endoscopic biopsy could not identify the tumor's origin because of the negative staining of various surface markers on immunohistochemistry...
