Intraductal papillary mucinous neoplasm with moderate dysplasia. Intraductal papillary mucinous neoplasms are tumors that grow within the pancreatic ducts (the pancreatic ducts are the "tubes" within the pancreas that are used to transport fluids to the bowel to help with digestion).

It is also known as intraductal papillary mucinous neoplasm (abbreviated IPMN ). Low and intermediate grade DCIS require cytologic, architectural and size criteria to be met. Several distinct noninvasive precursor lesions can give rise to invasive adenocarcinoma of the pancreas, and the prevention, detection, and treatment of these noninvasive lesions offers the potential to cure early pancreatic cancers. Mucinous Cystic Neoplasm (MCN) of Pancreas is an exocrine, benign or precancerous lesion, typically in the body and tail regions of the pancreas, and is characterized by the presence of mucin inside the cells (cytoplasm). Mucinous cystadenoma. Tubular Carcinoma Tubulolobular Carcinoma. Papillary Breast Cancer Diagnosis. Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is characterized by cystic dilation of the pancreatic duct, caused by mucin hypersecretion, with slow progression via the adenoma-carcinoma sequence mechanism. However, urine cytology is negative in most cases. It has been suggested that IPNB is the biliary counterpart of IPMN of the pancreas because these two lesions share several clinical and histopathologic features [13, 14] . Visual survey of surgical pathology with 11131 high-quality images of benign and malignant neoplasms & related entities. At endoscopy a so-called “fish-eye” ampulla of Vater, i.e., a bulging ampulla with extruding mucin, can be seen and is almost diagnostic for IPMN (Figure 2).
