- Intraductal Papillary Mucinous (IPM) Adenoma ;

- Dermoid Cyst (Cystic Teratoma) ;

II. Borderline:

- Mucinous Cystic Neoplasm with moderate dysplasia ;

- Intraductal Papillary Mucinous Neoplasm with moderate dysplasia ;

- Solid pseudopapillary neoplasm ;

III. Malignant:


- Ductal Adenocarcinoma ;

- Mucinous Non-Cystic and Signet-Ring Cell Carcinoma ;

- Adenosquamous Carcinoma ;

- Undifferentiated (anaplastic) carcinoma ;

- Undifferentiated carcinoma with osteoclast-like giant cell ;

- Mixed ductal-endocrine carcinoma ;

- Serous Cystadenocarcinoma ;

- Mucinous  cystadenocarcinoma ; Non-invasive ; Invasive
