I have tried to outline the history and development of Behcet's diseas
e, which was first described in 1937 by Hulusi Behcet, a Turkish Profe
ssor of Dermatology. The clinical picture is a triple symptom complex
consisting of relapsing aphthous ulcers in the mouth and over the geni
talia, and hypopion iritis. I have divided the developmental history o
f Behcet's disease into three periods: pre-Behcet, Behcet, and post-Be
hcet. Although similar clinical manifestations were mentioned in Hippo
cratic writings, clear examples of the symptomatic triad were not repo
rted until the first quarter of this century. Since 1937, Behcet's dis
ease has been a focus of active research. Exciting results concerning
the genetics, immunology, molecular biology, diagnosis, and treatment
of Behcet's disease have been obtained. It is hoped that the near futu
re will bring additional discoveries to help solving difficulties in B
ehcet's disease.
