Malignant fibrous histiocytoma (MFH) usually presents in the extremities or retroperitoneum. MFH arising from renal parenchyma or renal capsule is extremely rare, only few cases have been reported in literature and portend a poor prognosis. Renal MFH is differentiated from renal cell carcinoma, renal sarcoma, and sarcomatoid renal tumor only by histological and immunohistochemical studies. Since the therapeutic options for MFH are different, its early diagnosis is imperative. Herein, we report a case of a primary renal MFH in a 35-year-old male...

Liposarcomas are the most common type of mesenchymal neoplasm in soft tissue sarcomas. Although they frequently develop at the lower limbs or retroperitoneum, cases arising from the mediastinum are rare. Furthermore, the incidence of the inflammatory subtype of well-differentiated liposarcoma is known to be low. We experienced a case of a middle mediastinal liposarcoma in a 68-year-old woman. The tumor, which was completely resected, was 92 mm in diameter. The tumor consisted of two different imaging components that showed different growth and which were diagnosed as the lipoma-like subtype and inflammatory subtype of well-differentiated liposarcoma...

Carney triad is a synchronous or metachronous association of gastric gastrointestinal stromal tumors (GIST), pulmonary chondroma and extra-adrenal paraganglioma. The majority of patients have only one or two components of the triad, all three tumors being found in only about 2% of the patients at the time of the first diagnosis. The most common combination is gastric and pulmonary tumors. We report a case of Carney triad which was diagnosed at Masaryk Memorial Cancer Institute. A 57-year-old female patient with a history of gastric resection for leiomyosarcoma at the age of 14 and with an unclear pulmonary lesion evident on chest X-ray since as early as 2003...

Benefit from chemotherapy for well-differentiated/de-differentiated (WD/DD) liposarcomas has been reported to be minimal, however traditional response criteria may not adequately capture positive treatment effect. In this study, we evaluate benefit from first-line chemotherapy and characterize imaging response characteristics in patients with retroperitoneal (RP) WD/DD liposarcoma treated at The University of Texas MD Anderson Cancer Center. Response was assessed using RECIST (Response Evaluation Criteria in Solid Tumors) and an exploratory analysis of vascular response was characterized...

The extra-adrenal paraganglioma is a neoplasm originating in regional structures, uncommon in paediatrics. We report on a case of a 13-year-old patient who began with severe arterial hypertension, tachycardia, dilated cardiomyopathy and elevated levels of catecholamines in the blood and urine. The presence of a retrovesical pelvic mass in contact with the right vaginal dome was determined by imaging studies. A diagnosis of malignant extra-adrenal pelvic paraganglioma with lymph node metastases was reached through biopsy and the surgical resection of subsequent local recurrences...

REVIEW
Wesley W Ludwig, Michael A Gorin, Phillip M Pierorazio, Mohamad E Allaf
Robot assistance has been rapidly adopted by urological surgeons and has become particularly popular for oncological procedures involving the retroperitoneal space. The wide dissemination of robot assistance probably reflects the limited amount of operating space available within the retroperitoneum and the advantages provided by robot-assisted approaches, including 3D imaging, wristed instrumentation and the shorter learning curve compared with that associated with the equivalent laparoscopic techniques. Surgical procedures that have traditionally been performed using an open or laparoscopic approach, such as partial nephrectomy, radical nephrectomy, retroperitoneal lymph node dissection, nephroureterectomy and adrenalectomy, are now often being performed using robot assistance...

Background: Actinomycosis is a condition in which Actinomyces, a normal component of the oral and gastrointenstial flora, becomes pathogenic in the setting of damaged tissue, leading to widespread tissue destruction across fascial planes. Prior literature describing this condition is rare, particularly cases involving the retroperitoneum. In this study, we report a case of retroperitoneal actinomycosis caused by an infected, obstructing ureteral stone. Case Presentation: A 48-year-old woman with a history of substance abuse, malnutrition, and gastric bypass presented to the emergency room with a 3-week history of abdominal pain and fevers...

Less than 5-7% of germ cell tumors (GCTs) are extragonadal, being the central nervous system (CNS) the most common location in children, followed by retroperitoneum and mediastinum. Only 10% of mediastinal tumors are malignant and one third of these are pure seminomas (germinomas). We report the case of a 9 year-old boy with development of secondary sexual characteristics. Beta human chorionic gonadotropin (B-hCG) was elevated and a mediastinal mass was found. Final histology showed a pure seminomatous germ cell tumor (SGCT)...

BACKGROUND: Literature supports that very rarely the venom of "Hemotoxic Snake" (Russell's Vipers) affect haemostasis by secreting thrombin-like enzyme which promotes formation of unstable clots. Such clots could lead to fibrin deposition in micro circulation that in turn consume platelets and coagulation factors (consumption coagulopathy). Clinical presentation is mainly spontaneous bleeding and coagulopathy. In this case the significant effects of altered coagulation were observed in retropetitoneum and the patient presented in casuality as acute abdomen...

OBJECTIVE: We report an extremely rare case of ganglioneuroma involving the external auditory canal and middle ear. CASE REPORT: Ganglioneuromas are rare benign mature tumors thought to originate from sympathetic ganglions, with the highest incidence in the retroperitoneum, adrenal medulla, and posterior mediastinum. We present a case of ganglioneuroma of the external auditory canal and middle ear. At the age of 12 months, the patient was diagnosed with neuroblastoma stage IV with metastasis to the squamous temporal bone, bone marrow, and skull base...

Foreign bodies are rare and challenging issues leading to symptoms according to the location. Laparoscopy is a popular and minimally invasive method used for removal of foreign bodies in the abdominal cavity or retroperitoneum. We herein report a case with retroperitoneal foreign body that was removed through retroperitoneal single- port laparoscopy using nephroscope. To our knowledge this is the first case of removal of a retroperitoneal foreign body through single- port laparoscopy using nephroscope.

Mucinous cystadenomas and carcinomas of the ovary are well-established and common tumors. However, Primary retroperitoneal mucinous cystadenomas (PRMCs) are very rare. We present a 50-year-old woman referred to our institution with history of intermittent abdominal pain and palpable mass in her left flank. On CT-scan an unilocular cystic mass with thin wall measuring 171×155×108mm in the retroperitoneum was shown. Patient underwent surgical excision of the tumor. The histopathology examination showed a cystic mass with a fibrous wall and an epithelium composed of a single layer of columnar cells with mucin vacuoles compatible with PRMC...

Myxoid liposarcomas of the head and neck are mostly metastatic in nature, with the primary lesion usually in lower extremities or retroperitoneum. Primary mediastinal liposarcomas are even rarer. Although there have been previous cases reporting their incidence, there is no evidence of any case comprising of both the neck and the mediastinal region yet. We here present a case of a 43 year old male with a primary liposarcoma of the myxoid subtype originating in the anterior mediastinum. This is the first time such a case has presented in literature...

Lymphangioma is a rare, benign mesenchymal neoplasm, which is characterized by numerous intercommunicating cystic spaces containing lymphatic fluid. It is considered a congenital disease resulting from the obstruction of regional lymph drainage during the developmental period. Lymphangioma frequently occurs in the cervical neck and axilla, also in the retroperitoneum, mediastinum, mesentery, omentum, colon, and pelvis, rarely in the perirenal space. These tumors usually present in childhood, but infrequently, these also present in adults...

A 66-year-old man presented to our hospital because of abdominal pain for 5 days. A contrast abdominal CT raised the possibility of pancreatic carcinoma. FDG PET/CT showed increased FDG accumulation not only in the pancreas and the retroperitoneum, but also in the posterior mediastinum, which was not typical of pancreatic carcinoma. The patient was subsequently diagnosed having immunoglobulin G4-related disease following the histopathologic examination.

Immunoglobulin G4-related disease (IgG4-RD) is a regional or systemic multiorgan lymphoplasmacytic inflammatory disease of unknown etiology. It has been described in numerous organs and anatomic locations. Review of the literature shows that when the disease involves the retroperitoneum it causes retroperitoneal fibrosis. Tumefactive IgG4-RD of the retroperitoneum has not been previously reported. In this report, we describe the first case of a large retroperitoneal tumefactive IgG4-RD along with its histologic, cytologic, and immunohistochemical characteristics...
