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...

A 64-year-old woman underwent partial colectomy with partial resection ofthe retroperitoneum and D3 lymphadenectomy for descending colon cancer(tub2, pSS, ly0, v0, pN1, sH0, sP0, sM0, fStage III b). Three years and 6 months later, she underwent resection ofsegment 4 ofthe liver because ofliver metastasis. One year and 2 months later, her serum carcinoembryonic antigen level increased, and computed tomography showed an inferior mediastinal mass of 18mm in diameter. High FDG uptake by this tumor was seen on positron emission tomography-CT...

David E Gyorki, Peter F M Choong, John Slavin, Michael A Henderson
Soft tissue sarcoma is an umbrella term which encompasses over 60 histological tumour types. Approximately 15% of soft tissue sarcomas arise in the retroperitoneum. This complex group of tumours poses unique management challenges due to their often large size, histological heterogeneity and complexity of anatomical relationships. This review discusses the management of retroperitoneal tumours including the need for preoperative diagnosis, the evidence for neoadjuvant radiotherapy, the role of multivisceral resection and the importance of a multidisciplinary team approach...

RATIONALE: Intraabdominal fibromatosis is a rare benign tumor that often affects the mesentery or retroperitoneum, and can infiltrate adjacent organs. However, it is rare for fibromatosis to arise from the small intestinal wall. PATIENT CONCERNS: A 27-year-old female with a tangible abdominal tumor is described. DIAGNOSES: The computed tomography (CT) scan revealed a 7.5 cm, small intestine-associated tumor in the right abdomen. INTERVENTIONS: The patient received tumor resection and intestinal anastomosis...

The phenomenon of losing a green signal in synovial sarcoma (SS) using the SS18 break-apart probe by fluorescence in situ hybridization (FISH) has been poorly described. In this study, 12 SS with missing a green signal were identified. This series included 7 males and 5 females, aged 17 to 69 years (median, 38.5 years). The tumors involved the extremities (50%), mediastinum (16.7%), hypopharynx (8.3%), neck (8.3%), thyroid (8.3%), and retroperitoneum (8.3%). The tumors were classified as monophasic SS (58...

Authors present a case report of a patient who was diagnosed with a tumour of external iliac vein. Excision of venous wall with tumour and reconstruction of external iliac vein with venous patch was performed. Postoperative course was without complication. The patient is without complications and also without signs of recurrence in one year follow up. Tumours of venous wall are rare. They originate from vena cava inferior, less often from extremity veins. The most frequent primary tumours of vein wall are leiomyosarcomas...

Myelolipomas are rare benign tumors often detected as adrenal masses. Extra-adrenal myelolipomas are encountered even more rarely. The rate of detection of these lesions is increasing with improved radiological techniques. Because of their localization and morphological similarities to well differentiated liposarcomas, extra-adrenal myelolipomas need to be differentiated from other aggressive neoplasms. Preoperative imaging and percutaneous biopsy are important tools in the diagnosis of these lesions. We report a very rare case of an extra-adrenal perirenal myelolipoma associated with hemolytic anemia...

Chronic diarrhea in infants is a common condition for addressability to pediatric gastroenterologists. The causes are multiple and the delay in reaching the final diagnosis can lead to complications in the general condition of the child. The purpose of this review is to present the bio-clinical and histogenetic particularities of a rare clinical entity, characterized by tumoral causes of chronic diarrhea. VIPomas are neuroendocrine tumors that autonomously secrete vasoactive intestinal peptide (VIP). Watery diarrhea, hypokalemia and achlorhydria (WDHA) syndrome caused by VIP-producing tumors only rarely occurs in adult patients with non-pancreatic disease...

Paragonimiasis is a parasitic disease caused by Paragnonimus species. The primary site of infection is the lung, and extrapulmonary involvement is also reported. When infected with Paragonimus westermani, which is the dominant species in Korea, the central nervous system is frequently involved along with the liver, intestine, peritoneal cavity, retroperitoneum, and abdominal wall. Ectopic paragonimiasis raises diagnostic challenge since it is uncommon and may be confused with malignancy or other inflammatory diseases...

Extragonadal teratoma originating from the retroperitoneum represents less than 5% of all teratomas and accounts for less than 10% of all pediatric retroperitoneal neoplasms. To date, there has been no report of teratoma managed with LT. This study reports an infant aged 3 months with retroperitoneal immature teratoma involving the hepatic hilum, refractory to chemotherapy and treated with LT. The patient was referred to our hospital for management of a growing abdominal mass. Histopathology of a fine needle biopsy of the lesion suggested the possibility of a hepatoblastoma with teratoid features...

BACKGROUND: Walled-off pancreatic necrosis (WON) is a sequelae of acute pancreatitis that requires debridement, once infected. Recently, endoscopic necrosectomy has become the mainstay for management. However, peripancreatic collections that extend to the paracolic gutter or lesser sac, are more challenging to treat endoscopically. We report an endoscopic method for management of necrotic collections that extend into the paracolic gutter. METHODS: Consecutive patients, with symptomatic WON extending into the retroperitoneum, were included in a prospective registry...

Erdheim-Chester disease (ECD) is an extremely rare and aggressive form of non-Langerhans cell histiocytosis. ECD usually presents with bone pain in adults aged 40-60. Its etiology is unknown but it is thought to be either a reactive or neoplastic disorder. Recently, mutation of the proto-oncogene BRAF (BRAFV600E) has been found in more than 50% of cases. The multisystemic form of ECD is associated with significant morbidity, which may arise due to histiocytic infiltration of critical organ systems. The common sites of involvement are the skeleton, central nervous system, cardiovascular system, lungs, retroperitoneum, and skin...

Afferent limb syndrome (ALS) is caused by an obstruction of the afferent intestinal limb after ileal pouch-anal anastomosis. Here, we describe the first case of ALS to be successfully treated by a laparoscopic approach. A 27-year-old man underwent ileal pouch-anal anastomosis for ulcerative colitis. He was subsequently diagnosed with ALS and underwent ileopexy with laparotomy at 33 years old. Then, 21 months after the first ileopexy, he underwent laparoscopic ileopexy for ALS recurrence. The operative findings revealed a shortened fixed portion of the afferent limb adhering to the right pelvic retroperitoneum, which was regarded as the cause of the acute angulation...

Blunt abdominal trauma mostly results from motor vehicle accidents, recreational accidents, falls or assaults with commonly injured internal organs being the spleen, liver, retroperitoneum, small bowel, kidneys, bladder, colorectal, diaphragm and pancreas. Gastric rupture is quite uncommon. Isolated gastric perforations following blunt trauma to the abdomen are mostly seen in paediatric patients. It is uncommon in adult patients and even rarer is the occurrence of double gastric perforations. We report here with a case of isolated double gastric perforation in a 24-year-old male patient following vehicular accident...
