Alopecia Areata

definition

A microscopically inflammatory patchy hair loss occurring in sharply defined areas. It may also lead to diffuse hair loss and nail changes. ALOPECIA AREATA is probably an autoimmune disease. The characteristic initial lesion is commonly a circumscribed totally bald, smooth patch. At its margins, hairs which appear normal may also be very readily extracted. Subsequent progress is variable. The initial patch may regrow within a few months, or further patches may appear which may rapidly become confluent. ALOPECIA AREATA TOTALIS begins with rapidly growing circumscribed patches and ends with complete loss of all the hair on the head. In the most serious form, ALOPECIA AREATA UNIVERSALIS, all the hair on the body also falls out including eyebrows, lashes and pubic hair.
