The present study aimed to elucidate the clinicopathological characteristics of resected mucinous cystic neoplasm (MCN) with ovarian-type stroma and identify a surgical approach for MCN treatment, on the basis of Republic of Korean (Yonsei University College of Medicine, Seoul, South Korea) and Japanese (Nippon Medical School, Tokyo, Japan) bi-institutional collaboration. The present study retrospectively reviewed 55 MCNs with ovarian-type stroma using pathological re-examination. Clinicopathological features and preoperative clinical parameters were evaluated to predict malignant alterations in MCNs...

Acinar cell cystadenocarcinoma is a rare malignant epithelial neoplasm of the pancreas with a diffusely cystic, gross architecture in which the cysts are lined with neoplastic epithelial cells that demonstrate evidence of pancreatic exocrine enzyme production. This is the 10th case that has been reported in the literature. A 77-year-old male complaining of left hypochondrial pain was referred to our hospital for treatment of a pancreatic tumor. A huge, honeycomb-structured tumor was detected in the pancreatic tail...

The literature is highly conflicting on hepatobiliary mucinous cystic neoplasms (MCNs), aka "hepatobiliary cystadenoma/cystadenocarcinoma," largely because ovarian stroma (OS) was not a requirement until WHO-2010 and is not widely applied even today. In this study, MCNs (with OS) accounted for 24 of 229 (11%) resected hepatic cysts in one institution. Eight of the 32 (25%) cysts that had been originally designated as hepatobiliary cystadenoma/cystadenocarcinoma at the time of diagnosis proved not to have an OS during this review and were thus re-classified as non-MCN...

The aim of this study was to assess short-term outcomes of surgical treatment of pancreatic cystic tumors (PCTs). MATERIAL AND METHODS: We retrospectively reviewed medical records of 46 patients (31 women and 15 men) who had undergone surgery for pancreatic cystic tumors in our department. RESULTS: Pancreatic cystic tumors were located within the pancreatic head (21), body (11), tail (13), and whole pancreas (1). The following surgical procedures were performed: pancreatoduodenectomy (20), central pancreatectomy (9), distal pancreatectomy (3), distal pancreatectomy with splenectomy (3), distal extended pancreatectomy with splenectomy (2), total pancreatectomy (1), duodenum preserving pancreatic head resection (1), local tumor resection (4), and other procedures (2)...

Pancreatic cystic neoplasm is difficult to distinguish from pseudocyst as clinical and radiological evidences may not be sufficient to make an accurate diagnosis. This may result in misdiagnosis with inappropriate management. Hence, every effort should be made for their distinction to avoid internal drainage procedures for neoplasms instead of extirpation.

The common presenting symptoms of pancreatic cancer are abdominal pain, weight loss, and jaundice. Pancreatic adenocarcinoma presenting with diabetic ketoacidosis is a very rare emergent clinical condition. However, pancreatic ductal cystadenocarcinoma presenting with diabetic ketoacidosis was not reported. We describe a 60-year-old man with pancreatic cystadenocarcinoma presenting with diabetic ketoacidosis as the initial manifestation. It must be kept in mind that in diabetic ketoacidosis cases, the precipitating factor may be pancreatic ductal cystadenocarcinoma...

BACKGROUND: Contrast-enhanced harmonic endoscopic ultrasound (CEH-EUS) and quantitative-elastography endoscopic ultrasound (QE-EUS) are considered useful tools for the evaluation of solid pancreatic tumors (SPT). The aim of our study was to evaluate the diagnostic accuracy of CEH-EUS, QE-EUS, and the combination of both for the differential diagnosis of SPT. METHODS: Sixty-two consecutive patients (mean age 64.3 years, range 32-89 years, 44 male) who underwent EUS for the evaluation of SPT were prospectively included...

Pancreas is an extremely rare abdominal localization of the solitary fibrous tumor (SFT). It usually grows asymptomatically for a long time before a diagnosis can be made on the basis of symptoms and/or mechanical complications. Due to the rarity and nonspecific clinical presentation, this entity is diagnostically challenging. We present a 47-year-old man with a history of progressive epigastric pain for the last two weeks, and jaundice, who was admitted to hospital for further investigation. Cystadenocarcinoma was suspected based on the radiologic findings, and a pancreatoduodenectomy was performed...

Few reports of mucinous cystic neoplasm (MCN) in association with anaplastic carcinoma exist. The present study reported an unusual case of a 25-year-old female exhibiting large pancreatic MCN with anaplastic carcinoma. Notably, the patient was a Jehovah's Witness and therefore refused any blood transfusions. Preoperative diagnosis was invasive pancreatic MCN measuring 12.5 cm with ascites. Distal pancreatectomy was performed in combination with splenectomy and partial resection of the transverse colon. Intraoperative estimated blood loss was 400 ml, therefore a blood transfusion was not required...

The present study aimed to describe the characteristics of cystic pancreatic tumors using computed tomography (CT) and to evaluate the diagnostic accuracy (DA) of post-imaging three-dimensional (3D) reconstruction. Clinical and imaging data, including multi-slice spiral CT scans, enhanced scans and multi-faceted reconstruction, from 30 patients with pathologically confirmed cystic pancreatic tumors diagnosed at the Linyi People's Hospital between August 2008 and June 2014 were retrospectively analyzed. Following the injection of Ultravist® 300 contrast agent, arterial, portal venous and parenchymal phase scans were obtained at 28, 60 and 150 sec, respectively, and 3D reconstructions of the CT images were generated...

Cystic lesions of the liver are common and a major proportion is formed by parasitic cysts and simple cysts. Biliary cystic tumors (BCTs), namely biliary cystadenoma (BCA) and biliary cystadenocarcinoma (BCAC), are rare tumors which usually arise from the intrahepatic biliary tree. BCAs have malignant potential and are difficult to differentiate from BCAC pre-operatively on radiological imaging. Here we have presented 4 patients with BCTs and reviewed the literature pertaining to them.The data of four patients with BCA/BCAC diagnosed and treated at our institute were retrieved from our database and records were reviewed for age, sex, history, imaging, surgery, pathology and follow-up...

Cystic pancreatic neoplasms concern 1 to 2% of the pancreatic tumours. The serous ones are considered benign tumours but since 1989, several pancreatic serous cystadenocarcinomas (SCAC) cases have been reported. We report the case of a SCAC with a particular pattern. An 80-year-old female patient presented a 4-cm tumour in the neck of the pancreas associated with liver lesions evoking, on imagery exams, focal nodular hyperplasia nests. A cephalic duodenopancreatectomy and a resection of the liver lesions were carried out...

The literature on "variants" and "malignant" counterparts of pancreatic serous cystic neoplasms (SCNs) is highly conflicted. Clinicopathologic characteristics of 193 SCNs were investigated, along with a critical literature review. For the macrocystic (oligocystic) variant, in this largest series, a demographic profile in contrast to current literature was elucidated, with 21% frequency, predominance in female individuals (4:1), body/tail location (1.7×), younger age of patients (mean age, 50 y), and frequent radiologic misdiagnosis as other megacystic neoplasms...

Cystic neoplasms account for approximately 10-20% of all pancreatic cysts and 1% of pancreatic cancers. Serous cystadenomas are considered benign tumors with almost no malignant potential, and thus the management is typically only observation with serial imaging. According to the current World Health Organization classification, cases with distant metastases are defined as serous cystadenocarcinomas. To date, only 17 such cases with concomitant synchronous or metachronous liver metastasis have been described in the literature, and eight of these reports described treatment of secondary liver lesions...

Secondary achalasia or pseudoachalasia is a rare esophageal motor abnormality, which mimics primary achalasia; it is not easily distinguishable from idiopathic achalasia by manometry, radiological examination, or endoscopy. Although the majority of reported pseudoachalasia cases are associated with neoplasms at or near the esophagogastric (EG) junction, other neoplastic processes or even chronic illnesses such as rheumatoid arthritis can lead to the development of pseudoachalasia, for example, mediastinal masses, gastrointestinal (GI) tumors of the liver and biliary tract, and non-GI malignancies...

Hemobilia is an uncommon presentation of biliary tract or pancreatic disease. The investigation and management of this clinical problem is challenging. We report on a case of biliary tract hemorrhage from an otherwise asymptomatic right lobe biliary cystadenocarcinoma and review the literature on this unusual presentation. Hemobilia from primary or secondary liver tumors is not frequently reported in the literature. Hemobilia in this setting is usually observed in association with an obvious liver mass or abnormal liver function tests...
