Different types of benign or malignant cystic lesions can be observed in the pancreas. Pancreatic cystic lesions are classified under pathology terms into simple retention cysts, pseudocysts and cystic neoplasms. Mucinous cystic neoplasm is a frequent type of cystic neoplasm and has a malignant potential. Serous cystadenoma follows in frequency and is usually benign. Intraductal papillary mucin...

BACKGROUND Using carcinoembryonic antigen in discriminating between benign and malignant disease remains controversial. AIMS We aim to evaluate the diagnostic accuracy of cyst fluid carcinoembryonic antigen in predicting malignant pancreatic cystic lesions. METHODS We performed a literature search of MEDLINE and EMBASE. We included studies that compared the diagnostic accuracy of carcinoemb...

We describe a case of pseudomyxoma peritonei (PMP) successfully managed with intraperitoneal hyperthermic chemoperfusion. This case is unique due to the concurrent presence of intraductal papillary mucinous neoplasm (IPMN) of the pancreas. The patient presented with abdominal fullness. Abdominal computed tomography revealed massive ascites, thickened peritoneum, and a cystic lesion of the pancr...

Cystic neoplasms of the liver are divided into two types: mucinous cystic neoplasm and cystic intraductal papillary neoplasm of the bile duct. We herein report two cases of cystic and papillary neoplasm of the liver which differed from the abovementioned types. Case  1. A 70-year-old man. Radiologically, a cystic tumor measuring 20 mm in diameter was found at the hepatic hilum. Right hepatectom...

of > 1000 U/ml in pancreas cyst fluid is considered almost pathognomonic for a mucinous cystic neoplasm. A 32−year−old woman underwent abdominal computed tomography (CT) for evaluation of right upper quadrant pain, which revealed a 10−mm pancreatic tail cyst (l" Fig. 1a, b). The sharply demarcated cyst without septation did not communicate with the pancreatic duct. Follow−up CT, 4 months later,...

Primary pulmonary mucinous cystadenocarcinoma (PMCAC) is an extremely rare cystic neoplasm. A case of a 56-year-old male with a cystic lesion of the right lower lobe is described. Preoperative fine needle aspiration cytology and bronchoscopy were inconclusive. The patient underwent a formal right lower lobectomy and mediastinal lymph node dissection. Diagnosis was established intraoperatively. ...

CONTEXT The natural history of incidental branch-duct intraductal papillary mucinous neoplasm of the pancreas is still unknown. CASE REPORT The case of a 74-year-old man who had been diagnosed 14 years previously with an incidental branch-duct intraductal papillary mucinous neoplasm of the pancreatic head, 30 mm in size, without mural nodules and dilatation of the main pancreatic duct is here...

Primary mucinous adenocarcinoma of renal pelvis is a rare cystic neoplasm which mimics a hydronephrosis or pyonephrosis radiologically. We are presenting here a case report where mucinous cystadenocarcinoma of pelvicalyceal system was mimicking clinically and radiologically as pyonephrosis but diagnosed preoperatively through a simple and rapid test, Ultrasoundguided fine-needle aspiration cyto...
