23rd International Surgical Pathology Symposium


The 23rd International Surgical Pathology Symposium addresses common and uncommon diagnostic dilemmas encountered within surgical pathology practice. Prior to the symposium, participants will have the opportunity to review clinical histories, examine digital images, and formulate differential diagnoses. Case discussions highlight pathologic findings that characterize entities within the differential diagnoses.

  • Autopsy
  • Bone & Soft Tissue Pathology
  • Breast Pathology
  • Cardiovascular
  • Cytopathology
  • Dermatopathology
  • Gastrointestinal Pathology
  • Genitourinary Pathology
  • Head & Neck Pathology
