Overview

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

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
