Breast Pathology Fellowship

This fellowship is designed for trainees pursuing an academic career in diagnostic breast pathology. Training is accordingly focused on building expert diagnostic skills in clinical breast pathology, translational clinical research, and education. Clinical material is obtained from the UCSF Carol Franc Buck Breast Care Center and from numerous extramural confirmatory and challenging consultation cases. Successful applicants will have completed an accredited anatomic pathology or combined anatomic/clinical pathology residency program. Prior completion of a surgical pathology fellowship is a bonus but not required.

Clinical Training and Responsibilities

The fellow will complete clinical rotations managing in-house subspecialty breast biopsies and surgical cases, as well as confirmatory and complex consultation breast cases, in conjunction with faculty. Opportunities for graduated responsibility, including mock sign-out, are incorporated into the training plan. The fellow will additionally gain experience in diagnostic molecular breast pathology, including interpretation of HER2 fluorescence in situ hybridization (FISH) assays and targeted DNA sequencing panels in breast cancer. The fellow will participate in weekly breast tumor board conferences and radiologic-pathologic correlation conferences, as well as weekly molecular tumor board conferences when breast cases are presented.


Dedicated time will be reserved for participation in clinical and translational research projects in breast pathology. The fellow will be mentored in design and conduct of a research project that can be individually tailored to personal interest and expertise. Successful projects will be submitted for presentation at national meetings and prepared for peer-reviewed publication.


Teaching responsibilities include helping teaching gross and microscopic breast pathology to residents rotating on the breast pathology service, assisting in running weekly consensus and teaching conferences at the microscope, and helping to build a digital archive of breast pathology teaching cases. Opportunities for medical student teaching are also available if interested.
