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...

BACKGROUND: Non-Langerhans histiocytosis is a group of inflammatory lymphoproliferative disorders originating from non-clonal expansion of hematopoietic stem cells into cytokine-secreting dendritic cells or macrophages. Erdheim-Chester Disease (ECD) is a rare type of non-Langerhans cell histiocytosis characterized by tissue inflammation and injury caused by macrophage infiltration and histologic findings of foamy histiocytes. Often ECD involves the skeleton, retroperitoneum and the orbits...

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...

BACKGROUND: Poor-quality transitions of care from hospital to home contribute to high rates of readmission after complex abdominal surgery. The Coordinated Transitional Care (C-TraC) program improved readmission rates in medical patients, but evidence-based surgical transitional care protocols are lacking. This pilot study evaluated the feasibility and preliminary effectiveness of an adapted surgical C-TraC protocol. STUDY DESIGN: The intervention includes in-person enrollment of patients...

Angiomyofibroblastoma is a rare benign soft tissue tumor that arises predominantly in the female genital tract. It occurs less commonly in the scrotum, spermatic cord, and the retroperitoneum. Its diagnosis is based on specific histological and immunopathological features. However, the condition has never been previously described in the extremities. We present the first case report of angiomyofibroblastoma presenting as a slow-growing tumor in the foot of a 48-year-old lady.

This study aimed to assess the application of ultrasonography for preoperative diagnosis of retroperitoneal fibrosis (RPF). A total of 51 patients with clinically suspected RPF underwent transabdominal ultrasonography and ultrasound-guided histopathologic biopsy (tAU-UGHB). Retroperitoneal fibrosis was diagnosed in 35 patients; of these, 31 cases (88.6%) received a diagnosis using tAU-UGHB. The ultrasonographic images mainly showed solid, irregular isoechoic masses, which were present behind the retroperitoneum and surrounded the abdominal aorta, inferior vena cava, and ureters and had clear borders with the encapsulated structures...

Ureteral injuries due to gunshots are tend to be misdiagnosed because of concomitant vascular and intraabdominal organ wounds. Our case is a 23-year-old man who was admitted to the hospital with multiple abdominal gunshot wounds. Laboratory findings showed worsening anemia, and the computed tomography (CT) scan showed multiple lead bullets inside the abdomen and retroperitoneum. Patient was then taken to the operation room for laparatomy. There were many intestinal injuries and also a stable retroperitoneal hematoma...

The incidence of metastases to the neck in testicular cancer is 4-15%, and in 5% of these cases the metastasis is the only symptom. We present a 57-year-old asymptomatic male, who had previously been treated for colon cancer. A routine PET-CT showed enlarged lymph nodes in the retroperitoneum and at the neck. A core needle biopsy from the lymph node at the neck contained malignant cells, but not from colon cancer. The lymph node was extirpated, and pathological analysis proved it to be a metastasis from a testicular seminoma...

IgG4-related disease is a relatively newly described entity with findings that historically have been confused with a variety of other diseases with markedly different treatments and prognoses, including Sjogren's syndrome and MALT lymphoma. We present a case of IgG4-related disease of the salivary glands and review the literature on sonographic findings of IgG4-related disease. By connecting sonographic features of IgG4 disease with common ancillary features of IgG4 disease in other sites (pancreas, hilar lymph nodes, biliary tree, thyroid, and retroperitoneum), radiologists can play a pivotal role in the early diagnosis and identification of IgG4-related disease...

Ewing's sarcoma is a highly aggressive malignant tumour most commonly affecting long bones in children and adolescents. It is part of the Ewing's sarcoma family of tumours (ESFTs) that also include peripheral primitive neuroectodermal tumour and Askin's tumours. ESFTs share common cytogenetic aberrations, antigenic profiles and proto-oncogene expression with an overall similar clinical course. In 99% of ESFTs, genetic translocation with molecular fusion involves the EWSR1 gene on 22q12. Approximately 30% of ESFTs are extraosseous, most commonly occurring in the soft tissues of extremities, pelvis, retroperitoneum and chest wall...

Mediastinum and retroperitoneum are exceedingly rare sites for metastatic prostate cancer to occur. Here, we present the case of a 67-year-old male patient with incidental findings of mediastinal and retroperitoneal masses which were found to be due to metastatic prostate adenocarcinoma based on histopathology and immunohistochemical studies and later on supported by the significantly elevated Prostate Specific Antigen (PSA) levels. Prostate cancer should always be considered in the differential diagnosis of elderly men presenting with metastatic epithelial tumors even in unusual sites...

INTRODUCTION: Whilst pericardial effusion is a known complication of abdominal pathology, it is rarely reported following ruptured appendicitis and even more rarely requires drainage in that situation. This work has been reported in line with the SCARE criteria (Agha et al., 2016). PRESENTATION OF CASE: We report a 14-year-old male who developed extensive right hepatorenal and right paracolic abscesses, bilateral pleural effusions and a large pericardial effusion following laparoscopic appendicectomy...

The purpose of this case report is to show the potential benefit of Korean medicine therapy for treating multiple metastatic breast cancer. A 45-year-old Korean woman was diagnosed with right breast invasive ductal carcinoma in August 2012 but did not receive any treatment until October 2015 when she was diagnosed with stage 4 right breast cancer with multiple liver, bone, mesentery, retroperitoneum, and axillary lymph node metastases. After chemo-port insertion, she was treated with palliative chemotherapy and the first line of trastuzumab and paclitaxel, and the port was removed due to port infection...

Pheochromocytoma arising from outside the adrenal glands is also called paraganglioma. When it occurs below the diaphragm, in the organ of Zuckerkandl or retroperitoneum, it is also called extra-adrenal pheochromocytoma. Paragangliomas are rare tumors which arise from neuroendocrine cells and extra-adrenal paragangliomas (EAPs) account for only 10-15% if all paragangliomas and may present incidentally as a symptomless mass. Typical triad of sweating, headache and fluctuating hypertension if not present makes preoperative diagnosis difficult...
