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...

Carcinosarcomas (CS) are uncommon, highly aggressive, biphasic tumours consisting of both sarcomatous and carcinomatous elements. They appear to originate from a common cell of origin, either via transformation from a single premature precursor or conversion of a mature epithelial cell through an epithelial-mesenchymal transition. CS should be considered a unique cancer subtype with cells typically displaying diffuse mitotic activity and widespread atypical mitoses predisposing to early metastasis and a tendency to local recurrence following resection...

Indeterminate cell histiocytosis (ICH) is a very rare histiocytic disease. We reported a case of generalized ICH presenting as eroded papules and crusts, accompanied with intermittent fever, pulmonary disorder, lymphadenectasis in the mediastinum, and the retroperitoneum. The histopathology indicated a neoplasm that was composed of small nests of large cells with ample pale cytoplasm. Immunohistochemistry results and the absence of Birbeck granules led us to the diagnosis of ICH. Four months later, the patient died of anemia, ascites, and swelling of the limbs...

We report a case of sporadic isolated hemangioblastoma arising from the retroperitoneum and provide a review of the scarce literature regarding this very rare tumor. Furthermore, we thoroughly describe the pathologic features and the broad differential diagnosis that should always be included in the study of any retroperitoneal soft tissue mass to arrive at the final diagnosis.

BACKGROUND: Ganglioneuroma (GN) is a rare benign tumor arising from the neural crest cells. The reported incidence of GN is one per million population. As a primary retroperitoneal tumor, it constitutes only a small percentage of 0.72 to 1.6%. GN can arise de novo or as a result of maturation of a neuroblastoma either spontaneously or after chemotherapy. The most common location is the posterior paraspinal mediastinum, retroperitoneum, neck and adrenal gland. However, GN can potentially occur anywhere along the peripheral autonomic ganglion sites...

Leiomyoma of deep soft tissue is a rare type of benign smooth muscle tumor that mostly occurs in the retroperitoneum or abdominal cavity of women, and about which very little genetic information exists. In the present study, eight leiomyomas of deep soft tissue were genetically analyzed. G-banding showed that three tumors carried rearrangements of the long arm of chromosome 12, three others had 8q rearrangements, the 7th tumor had deletion of the long arm of chromosome 7, del(7)(q22), and the 8th had aberrations of chromosome bands 3q21~23 and 11q21~22...

The advances seen in the treatment of testicular cancer are among the great achievements in modern medicine. These advances were made possible by the collaborative efforts of cancer researchers around the world. Investigators have been able to address many questions regarding the treatment of patients with disease limited to the testis, those with metastasis to the retroperitoneum only, and those with advanced metastatic disease. Questions answered include the chemotherapeutic agents to be used and in what combinations, the proper intensity of treatment and appropriate dosing, the optimal number of cycles of chemotherapy according to validated risk stratification, appropriate surgical approaches that preserve sexual function, the treatment of relapsed disease, what supportive care measures to take, and survivorship issues following treatment of testicular cancer...

Pseudoaneurysm of peripancreatic vessel is a rare complication of pancreatitis. The splenic artery is the most commonly affected vessels close to the pancreas. Pseudoaneurysm of right gastroepiploic artery is rare. It can rupture into Gastro Intestinal (GI) tract, retroperitoneum, peritoneal cavity, biliopancreatic duct or pseudocyst. Clinical diagnosis of unruptured pseudoaneurysm is rarely possible because there are no specific signs and symptoms. We hereby report a case of pseudoaneurysm of aberrant right gastroepiploic artery in 30-year-old male which presented with history of epigastric pain and lump with episode of haematemesis and malena...

It is important to distinguish between leiomyosarcoma (LMS) and dedifferentiated liposarcoma (DDLS) in the retroperitoneum. The dedifferentiated component of DDLS shows an LMS-like morphology in some cases; thus, detailed evaluation is necessary to achieve an accurate diagnosis. Immunohistochemically, MDM2 and myogenic markers provide clues for the diagnoses. However, immunoreactivity for MDM2 and myogenic markers has not been well studied in retroperitoneal LMS and DDLS. Here, we compared the clinicopathological data of 20 retroperitoneal tumors initially diagnosed as LMS with that of 36 cases of retroperitoneal DDLS and conducted an immunohistochemical study...
