We present a 37-year-old male patient with a mature teratoma of the right testicle with a focus of embryonal carcinoma. This patient's tumor metastasized radically to the retroperitoneum, right adrenal gland, bilateral lungs, and liver. A metastatic teratoma with embryonal carcinoma in males is a very rare case. We will describe our patient's case, diagnostic workup, and management in detail, in addition to reviewing the related literature.

A disease associated with immunoglobulin IgG4 is a rare unit with very variable symptoms. We describe the course and treatment of the disease in a patient who presented with multiple lymphadenopathy and infiltrates in the area of the retroperitoneum and pelvis and signs of chronic sclerosing pancreatitis. The disease was clinically manifested by a significant loss of weight, but also by a loss of perception of taste and smell. The diagnosis was made based on a high amount of IgG4 expressing plasma cells in the sampled tissue and an increased concentration of immunoglobulins of type IgG and mainly subclass IG4...

Liposarcoma is a rare neoplasm in rats and is characterized by the presence of lipoblasts containing multiple cytoplasmic vacuoles. We encountered a rare type of liposarcoma in a male SD (Crj:CD(SD)IGS) rat during a long-term study to gather background data. At necropsy at 105 weeks of age, there was a large amount of fatty tissue covering the mesentery, pancreas, and retroperitoneum; a white nodule in the right kidney; and paleness of the liver. Microscopically, the tumor had a well-differentiated component and dedifferentiated high-grade component...

AIM: Pancreaticopleural fistula (PPF) is a rare complication of acute or chronic pancreatitis. When the pancreatic duct disrupts, pancreatic fluid may leak into the retroperitoneum and fistulate into the pleural cavity. Patients usually present with thoracic complaints, making it hard to suspect an abdominal etiology. Although PPF is uncommon, one must consider this diagnosis in patients with thoracic complaints and a history of alcohol abuse or pancreatitis. METHODS: We present an illustrative case and review of the literature on PPF...

Resection of the inferior vena cava (IVC) is a rare surgical technique that is occasionally combined with nephrectomy in the setting of renal malignancy with intravascular tumor extension. While this may be fairly well tolerated in some patients due to extensive collateralization in the venous system, there is a clear potential for lower extremity venous insufficiency and deep vein thrombosis (DVT). This report describes a patient who underwent right nephrectomy and segmental IVC resection from the subhepatic space to the iliac confluence, which was complicated by profoundly symptomatic lower extremity DVT and gastrointestinal hemorrhage due to system-to-portal shunting...

INTRODUCTION: Pirfenidone was approved in 2014 for the treatment of idiopathic pulmonary fibrosis. Pirfenidone inhibits several factors such as tissue growth factor-β and platelet-derived growth factor, leading to decreased epithelial and fibroblast proliferation and collagen synthesis. The drug improves progression-free survival and is well tolerated, with minimal side effects. However, data on its long-term effects are lacking. CASE PRESENTATION: We present a rare case in which an undifferentiated pleomorphic sarcoma developed in a 59-year-old man with idiopathic pulmonary fibrosis who was treated with pirfenidone for more than a year...

INTRODUCTION: Hibernoma is a very rare benign tumor that arises from vestigial remnants of fetal brown adipose cells and usually manifests as a slowly growing, painless soft-tissue mass. It mainly occurs in adults, in the third and fourth decade of life, slightly more in women and is commonly seen in the subcutaneous regions of the back, neck, thighs and retroperitoneum. It was originally described in 1906 by Merkel, who named it "pseudolipoma". In 1914, Gery derived the name hibernoma from the tumor's histological similarity to brown fat in hibernating animals...

Introduction The rupture of thoracoabdominal aneurysms (rTAA) represents one of the major challenges to the vascular surgeon. Recent developments in the endovascular armamentarium and the high mortality from open surgery make endovascular treatment an attractive option. Devices to be used in an emergency environment should be "off-the-shelf" and include, among others, EVAR snorkel/chimney and branched endoprosthesis (T-branch, Cook®). METHODS: We describe the case of a 70-year-old patient who was admitted to the emergency room due continuous low back pain with 3 days of evolution...

Well-differentiated papillary mesothelioma is a rare tumor occurring predominantly in the peritoneum of young women, a few with history of asbestos exposure. A 28-year-old woman presented with ascites and pain abdomen. Ultrasonography and computed tomography scan of the abdomen revealed a mass in the retroperitoneum measuring 15 cm × 12 cm. Histopathological examination along with immunohistochemistry (IHC) confirmed it to be a papillary mesothelioma in the peritoneum. It is difficult to differentiate from more common malignant mesothelioma and papillary adenocarcinoma, which also have poorer prognosis...

Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of diffuse large B-cell lymphoma (DLBCL). Furthermore, tumorigenesis is extremely rare. An 80-year-old man was admitted to our hospital with nervous symptoms. Imaging tests showed a brain tumor and mass lesions in the seminal vesicle and retroperitoneum. Transrectal biopsy of the seminal vesicle helped diagnose the patient with DLBCL. The patient's general status deteriorated rapidly, and he died on the 23rd day after admission. An autopsy was performed and the pathological diagnosis was DLBCL, specifically suspected as IVLBCL, with nodular masses in the brain and seminal vesicle...

Immunoglobulin G4 related disease (IgG4-RD) is a fibro-inflammatory disease of unknown etiology, characterized by lesions in the form of tumors, elevated serum IgG4 levels, plasma cells with significant IgG4 infiltration, accompanied by phlebitis obliterans and fibrosis. This disease usually has multiorgan disease, including pancreas, biliary tract, salivary glands, peri orbital tissues, kidneys, lungs, lymph nodes and retro peritoneum. IgG4-RD mainly affects men with a predominance of age by young adults until old age...

OBJECTIVE: Describe the imaging appearance of well-differentiated liposarcoma with myxoid stroma (WDLMS) and correlate with histopathology. MATERIALS AND METHODS: A keyword search of the institution medical records was performed from 1 January 2000 to 30 June 2017. The histopathology slides of cases identified in this fashion were then reviewed by a pathologist. Additional cases were prospectively collected from extramural referrals and tumor boards. Diagnostic imaging studies of pathologically proven cases of WDLMS were then reviewed in consensus and correlated with pathology...

A 53-year-old woman was diagnosed with endometrial carcinoma by vaginal bleeding. F-18 fluorodeoxy glucose positron emission tomography PET/CT (F-18 FDG PET/CT) scan for staging showed intense focal FDG uptake in the endometrium suggesting endometrial malignancy. PET/CT showed multiple node uptakes in the pericaval region, paraaortic region, common iliac, and both internal iliac and external iliac regions suggesting multiple pelvic and retroperitoneal node metastases. MRI showed multiple metastatic lymphadenopathy in the retroperitoneum and pelvic cavity...

Solitary fibrous tumor (SFT) is a mesenchymal neoplasm that was originally described to be localized in the pleura, but thereafter, this has been reported in several anatomic sites. Although the etiology of the neoplasm remains largely unknown, the pathogenesis seems to be related to an NAB2-STAT6 fusion gene due to paracentric inversion on chromosome 12q13. The diagnosis of extrapleural SFT is challenging, owing to its rarity, and requires an integrated approach that includes specific clinical, histological, immunohistochemical, and even molecular findings...

Traumatic retroperitoneal injuries constitute a challenge for trauma surgeons. They usually occur in the context of a trauma patient with multiple associated injuries, in whom invasive procedures have an important role in the diagnosis of these injuries. The retroperitoneum is the anatomical region with the highest mortality rates, therefore early diagnosis and treatment of these lesions acquire special relevance. The aim of this study is to present current published scientific evidence regarding incidence, mechanism of injury, diagnostic methods and treatment through a review of the international literature from the last 70 years...

This report describes an estrogen receptor-positive breast cancer patient, who relapsed at two and a half years after the completion of adjuvant chemotherapy while being on the aromatase inhibition. Based on the clinical evidence for potential sensitivity of the tumor to hormone ablation, everolimus was added to continuing exemestane treatment. Oral chemotherapy was administered at further disease progression, however, it lasted only for 10 days due to rapidly deteriorating condition of the patient. BRCA test was performed just before the failure of endocrine therapy and revealed a gross deletion within BRCA2 gene...

Ureteric trauma is rare, occurring in < 1% of all traumas. We present a unique case of a 13 year old female who sustained a penetrating abdominal injury from a bicycle handlebar. Upon initial examination there was herniation of bowel through the abdominal wound, so exploratory laparotomy was performed. A serosal injury of the colon and bleeding mesenteric veins were encountered; the retroperitoneum was not explored at that time. Postoperative course was remarkable for a doubling of the serum creatinine, increasing abdominal distention and pain...

PURPOSE: To assess overall targeting accuracy for CT-guided needle insertion using prototype robotic system for common target sites. MATERIALS AND METHODS: Using CT guidance, metallic (2 × 1 mm) targets were embedded in retroperitoneum (n = 8), kidneys (n = 8), and liver (n = 14) of 8 Yorkshire pigs (55-65 kg). Bronchial bifurcations were targeted in the lung (n = 13). CT datasets were obtained for planning and controlled needle placement of commercially available 17- to 19-gauge needles (length 15-20 cm) using a small, patient-mounted, CT-guided robotic system with 5° of motion...
