Renal cell carcinoma metastases to pancreas, thyroid, and contralateral adrenal gland are decidedly uncommon. Clear cell renal cell carcinoma (CCRCC) is the most frequent subtype. Cytology diagnosis may be challenging. A 74-year-old male with remote history of vocal cord malignancy and hypertension presented with abdominal pain. Computed tomography (CT) revealed 8.4 cm left renal mass highly suspicious for renal cell carcinoma, a 1.8 cm mass within vessels near left adrenal and a 2.5 cm mass in pancreatic tail...

Most cases of pancreatoblastoma, a rare malignant epithelial tumor of the pancreas, are seen in the pediatric population. The rarity of pancreatoblastoma, the similar radiologic findings to those seen in other pancreatic lesions, and its histopathologic heterogeneity, make its preoperative diagnosis in adults a real challenge. We report ultrasound, computed tomography and magnetic resonance imaging correlative findings of a histologically proven pancreatoblastoma in a 37-year-old woman. Pancreatoblastoma should be considered in the differential diagnosis of a pancreatic mass presenting uncommon imaging features...

Schwannomas are mesenchymal tumors originating from Schwann cells in peripheral nerve sheaths. Although the tumor can be located in any part of the human body, the most common locations are the head, neck, trunk and extremities. Pancreatic schwannomas are rare. To our knowledge, only 64 cases of pancreatic schwannoma have been reported in the English literature over the past 40 years. In this paper, we present a pancreatic schwannoma in a 59-year-old female. Ultrasound, computed tomography and magnetic resonance imaging revealed the tumor located in the pancreatic body; however, accurate diagnosis was hard to obtain preoperatively and a pancreatic cystadenoma was preliminarily considered...

INTRODUCTION: In pancreatic ductal adenocarcinoma (PDA), surgical resection is the only curative treatment, but due to its late clinical presentation only 15-25% patients are candidates for curative resection. The aim of this prospective, single-center study is to determine the diagnostic utility of preoperative PET-CT for early detection of PDA and early panIN lesions. METHODS: We studied the histopathological features of PDA and different panIN lesions in 139 surgical samples from patients undergoing pancreatic resection (from 2010-2014), comparing these results with preoperative PET-CT and MDCT study...

BACKGROUND: Paragangliomas are rare neoplasms that originate from the neural crest. They are malignant in approximately 10% of cases, with a 50% survival rate at 5 years from diagnosis. In most cases, manifestations of malignancy (such as metastasis) are lacking, and paragangliomas are considered benign lesions. Pancreatic paragangliomas are extremely rare, with only 31 cases described in the scientific literature to date. CASE SUMMARY: Here we describe a case of a 55-year-old Caucasian male patient referred to our institution in September 2013 for lumbar pain lasting five months...

Autoimmune pancreatitis (AIP) is a unique form of pancreatitis, histopathologically characterized by dense lymphoplasmacytic infiltration and fibrosis of the pancreas with obliterative phlebitis. AIP is associated with a good response to steroid therapy. Differentiation between AIP and pancreatic cancer to determine a preoperative diagnosis is often challenging, despite the use of various diagnostic modalities, including computed tomography (CT), magnetic resonance imaging and endoscopic retrograde cholangiopancreatography...

Intraductal papillary mucinous neoplasms (IPMNs) are pancreatic cancer precursors incidentally discovered by cross-sectional imaging. Consensus guidelines for IPMN management rely on standard radiologic features to predict pathology, but they lack accuracy. Using a retrospective cohort of 38 surgically-resected, pathologically-confirmed IPMNs (20 benign; 18 malignant) with preoperative computed tomography (CT) images and matched plasma-based 'miRNA genomic classifier (MGC)' data, we determined whether quantitative 'radiomic' CT features (+/- the MGC) can more accurately predict IPMN pathology than standard radiologic features 'high-risk' or 'worrisome' for malignancy...

PURPOSE: The purpose of this study was to evaluate the degree of fatty infiltration (FI) of the pancreas using area-based assessment on computed tomography (CT) (CT area-based assessment) in its correlation and agreement/concordance with histopathology-based assessment. Furthermore, we examined whether CT area-based assessment was better than CT attenuation index-based assessment. MATERIALS AND METHODS: We retrospectively evaluated the degree of FI of the pancreas in 37 pancreatic cancer patients who had undergone preoperative CT and pancreaticoduodenectomy...

Endometriosis occurs in 5%-10% of fertile women, usually in the pelvic region, such as the ovaries, uterine ligaments, pelvic peritoneum, and rectovaginal septum. A mesenteric endometriotic cyst is an exceptional observation and difficult to diagnose preoperatively. We report a case of a large mesenteric endometriotic cyst treated by laparoscopy. A 21-year-old Caucasian woman was admitted as an emergency to our Academic Hospital on the 30th day postpartum for abdominal pain and a palpable epigastric mass. A CT scan revealed a mass measuring 7...

PURPOSE: Total pancreatectomy (TP) for pancreatic neoplasms is associated with high morbidity and mortality rates. However, with recent advances in surgical techniques and improved postoperative management, the number of cases with clinical indications for TP is increasing. Here, we evaluated the clinical outcomes post-TP. MATERIALS AND METHODS: Patients (n = 41) who underwent TP between 2004 and 2011 at Tokyo Women's Medical University were retrospectively examined...

Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare neoplasm which primarily affects young women without specific clinical manifestation. Computed tomography and magnetic resonance imaging contribute to the preoperative diagnosis of SPN. Surgery is the main treatment approach for SPN and more research of radiation and chemotherapy is needed. Tumor diameter larger than 5 cm, tumor infiltrating nerve, vessel or adipose tissue can increase the risk of recurrence. However, these patients can still get good prognosis after surgical resection...

Solitary fibrous tumor (SFT) is a mesenchymal tumor typically located in the pleura, but can also be found as an asymptomatic mass in other areas, including the liver, peritoneum, kidney and salivary glands. However, SFT rarely locates in the pancreas. We present such a case of pancreatic SFT, along with a review of all reported cases. A 55-year-old man was treated surgically for an asymptomatic pancreatic mass after a rigorous preoperative control. Histologic examination of the resected specimen showed characteristics of an SFT...

The localization and diagnosis of microgastrinomas in a patient with multiple endocrine neoplasia type 1 is difficult preoperatively. The selective arterial calcium injection (SACI) test is a valid diagnostic method for the preoperative diagnosis of these invisible microgastrinomas. We report a rare case of multiple invisible duodenal microgastrinomas with severe duodenal stenosis diagnosed preoperatively by using the SACI test. A 50-year-old man was admitted to our hospital with recurrent duodenal ulcers. His serum gastrin level was elevated to 730 pg/ml...

OBJECTIVE: The completeness of primary cytoreductive surgery for Stage IV epithelial ovarian cancer is associated with greater progression free survival and overall survival Winter et al. (2008) [1]. Cytoreduction to no gross residual disease in patients with bulky upper abdominal disease presents significant surgical challenges, highlighting the importance of specialized and comprehensive surgical training in the treatment of advanced ovarian cancers Zivanovic et al. (2008) [2]. Extensive upper abdominal surgical procedures have shown to improve the ability to achieve cytoreduction to no gross residual disease Chi et al...

Gastrinoma is a very rare tumor leading to gastrin hypersecretion and characterised by Zollinger-Ellisson syndrome (ZES) i.e. severe gastric and duodenal ulceration and profuse diarrhea. This disease can be sporadic or familial within a multiple endocrine neoplasia type 1 (MEN-1) syndrome. Diagnosis is based on hypergastrinemia/hypercholrhydria. Tumors are usually located in the duodeno-pancreas. Preoperative tumor location by CT, echoendoscopy and fibroscopy is not always possible because of the small size of the lesion that are frequently multiple...

BACKGROUND: Postoperative pancreatic fistula (POPF)-often caused by pancreatic injury during dissection of the peripancreatic lymph nodes-is a serious complication after gastric cancer surgery. We defined protruding pancreatic tissue on the anterior side of the pancreas head as "process of the pancreas head" (PPH) and investigated whether PPH is a predictable risk factor for POPF after laparoscopic gastrectomy. METHODS: We reviewed 255 patients who underwent laparoscopic total or distal gastrectomy for gastric cancer...
