Cellular Classification
Pancreatic cancer includes the following carcinomas:
Malignant
- Duct cell carcinoma (90% of all cases).
- Acinar cell carcinoma.
- Papillary mucinous carcinoma.
- Signet ring carcinoma.
- Adenosquamous carcinoma.
- Undifferentiated carcinoma.
- Mucinous carcinoma.
- Giant cell carcinoma.
- Mixed type (ductal-endocrine or acinar-endocrine).
- Small cell carcinoma.
- Cystadenocarcinoma (serous and mucinous types).
- Unclassified.
- Pancreatoblastoma.
- Papillary-cystic neoplasm (Frantz tumor). (This tumor has lower malignant potential and
may be cured with surgery alone.)[1,2]
- Invasive adenocarcinoma associated with cystic mucinous neoplasm or intraductal papillary mucinous neoplasm.
Borderline Malignancies
- Mucinous cystic tumor with dysplasia.
- Intraductal papillary mucinous tumor with dysplasia.[3]
- Pseudopapillary solid tumor.
