The men behind the eponym: Francis E. Senear, Barney Usher, and the Senear-Usher syndrome

Abstract

This historical review will summarize the report of Francis Senear and Barney Usher on a disease that they called pemphigus erythematodes and which later became pemphigus erythematosus (the Senear-Usher syndrome). It will then outline the lives of these two men. Finally, it will review the literature on that condition and relate the views of various authorities as to whether pemphigus erythematosus is merely pemphigus foliaceus, a variant of pemphigus foliaceus, a syndrome combining features of lupus erythematosus and pemphigus or whether pemphigus erythematosus (Senear-Usher syndrome) is a distinct and separate disease.
