Pancreatic mesenchymal neoplasms
Updates to Article Attributes
Pancreatic mesenchymal neoplasms (or pancreatic nonepithelial neoplasms) are a group of rare pancreatic neoplasms that arise from the structural elements of the pancreas (nerves, fat, lymph), rather than from the exocrine or endocrine cells of the pancreas. Neoplasms from exocrine and endocrine cells result in more familiar pancreatic neoplasms such as pancreatic ductal adenocarcinoma, IPMN, and pancreatic endocrine tumours (formerly termed "islet cell tumours").
Epidemiology
Pancreatic mesenchymal neoplasms are rare and represent at most 1-2% of pancreatic neoplasms 2.
Pathology
Pancreatic nonepithelial tumours includecan be broadly divided into those that are benign and those that are malignant.
Benign
- pancreatic neurofibroma
- pancreatic schwannoma
- pancreatic ganglioneuroma
- pancreatic desmoid tumour
- pancreatic lipoma
- pancreatic perivascular epithelioid cell tumour (pancreatic PEComa)
- pancreatic mature cystic teratoma (pancreatic dermoid)
- pancreatic lymphangioma
Malignant
Radiographic features
A disparate group of tumours, they have many different imaging appearances, based on their underlying histology. As a group, these neoplasms tend to better-marginated than the more infiltrative pancreatic ductal adenocarcinoma 1.
