Key anatomy and histological features
  • Head, body and tail 
  • Exocrine pancreas: Majority of pancreatic tissue, glandular epithelial cells
Predominantly at the head
Drain through pancreatic duct
Acini, ducts
  • Endocrine pancreas: Islets, pale endocrine cells
Alpha: secrete glucagon (20% 0f cells)
Beta: insulin (70% of cells)
Delta: somatostatin (5% of cells)
PP cells: pancreatic polypeptide
Non neoplastic disorders
Cystic neoplasm
Non cystic neoplasm
Gallbladder disorders

Lymphoid neoplasms

Lymphocytic neoplasms Updated: 05/17/2020 © Jun Wang, MD, PhD Terminology Lymphoma : Proliferations forming discrete tissue masses Leukemia : Widespread involvement of the bone marrow and usually the peripheral blood Any "lymphoma" can present with or evolve to a leukemic picture, and any "leukemia" can occasionally present with a mass lesion Other hematology terms Important risk factors Immunodeficiency (primary or secondary) Autoimmune disorders Viruses (HIV, KSHV/HHV8, HTLV-1) H. pylori infection Radiation Chemotherapy Diagnostic approaches Complete history, especially those with possible epidemic characters, such as Burkitt lymphoma CBC, Bone marrow Morphology/immunohistochemistry Immunofluorescence flow cytometry Cytogenetic studies Molecular studies Commonly used markers All lymphomas: CD45 B-cell neoplasms: CD5, CD10, CD19, CD20, CD79a, CD23, bcl2, bcl6, cyclin D1, light chai
