Overview

Pancreatic cancer can be classified into malignant and borderline malignant. Duct cell carcinoma is the most common type of pancreatic cancer.

Classification

• Cellular Classification of Pancreeratic Cancer

• Pancreatic cancer includes the following carcinomas:

• Malignant

• Duct cell carcinoma (90% of all cases)
• Acinar cell carcinoma
• Adenosquamous carcinoma
• Cystadenocarcinoma (serous and mucinous types)
• Giant cell carcinoma
• Invasive adenocarcinoma associated with cystic mucinous neoplasm or intraductal papillary mucinous neoplasm
• Mixed type (ductal-endocrine or acinar-endocrine)
• Mucinous carcinoma
• Pancreatoblastoma
• Papillary-cystic neoplasm (Frantz tumor). This tumor has lower malignant potential and may be cured with surgery alone
• Papillary mucinous carcinoma
• Signet ring carcinoma
• Small cell carcinoma
• Unclassified
• Undifferentiated carcinoma

• Borderline Malignancies

• Intraductal papillary mucinous tumor with dysplasia
• Mucinous cystic tumor with dysplasia
• Pseudopapillary solid tumor
