DERMATOLOGY

A Manual of Differential Diagnosis
Third Edition
By
Stanferd L. Kusch, MD


Some of the more persistent residents (and
dermatologists in private practice) tracked me down
at my solo private practice in Bend, Oregon and
requested what few copies I had left from the earlier
printings.

Then, in July of 2003, after having sent out one of my
last remaining copies of the manual, I received an
unexpected call from an attorney for Taro
Pharmaceuticals, U.S.A., Inc. (Taro) wanting to
know if I still held the copyright. Apparently, Dr.
Jacob Levitt, a dermatology resident at Mount Sinai
Wheeland, Richard Hoshaw, and Gary Wright who
provided input to the original edition in 1979-80 and
Mark Everett, the former Chairman of the
Department of Dermatology at the University of
Oklahoma, who encouraged me to compile and
publish my “lists”. Stan Kusch, MD
