Outstanding training in dermatopathology has five components:

  1. Two week rotation(s) in dermatopathology. The initial rotation will be in the first year for AP-only residents and in the second year for AP/CP residents.  Residents with particular interest in dermatopathology may elect additional rotations in subsequent years.  The rotation is a tutorial with Basil Horst, MD. Twice daily, the resident studies groups of approximately 20 unknown slides and then reviews the cases with Dr. Horst.
  2. Weekly didactic lectures by Sameera Husain, MD, on Wednesdays at 1:00 PM. These are held jointly with Dermatology residents and focus on basics of dermatopathology and clinical-pathologic correlations.
  3. Weekly unknown slide review sessions at the multiheaded microscope with Dr. Horst on Thursdays at 4:00 PM.  Dermatology residents also participate. Diagnostic criteria and clinical-pathologic correlations are emphasized.
  4. Weekly unknown slide review sessions with David N. Silvers, MD, Director of Dermatopathology.  These are also in conjunction with Dermatology residents and are on Wednesday afternoons at 2:00 P.M.  Dr. Silvers leads a discussion of the characteristic dermatopathology findings, pathologic differential diagnosis, and clinical-pathologic correlations.
  5. The first four activities focus on biopsy diagnosis.  Larger resections of dermatologic lesions come to general surgical pathology and the residents will review them on this rotation.

Drs. Horst and Husain both completed training in Anatomic Pathology in our department prior to fellowship training in dermatopathology.  Additional information on them, Dr. Silvers, and the Division of Dermatopathology is available at:

Many residents with particular interest in dermatopathology have conducted research in collaboration with faculty of the Department of Dermatology and with the Division of Dermatopathology. 

There is no Fellowship in Dermatopathology offered at Columbia, but interested pathology residents have uniformly been successful in joining the Dermatopathology fellowship program of their choice.
