Focal atrichia: What is it?
Focal trichina is a term which refers to a specific observation seen on the scalp of patients with androgenetic alopecia. Those with focal atrichia have small circular areas devoid of hair.
This is a feature of advanced male balding (androgenetic alopecia) and also female pattern androgenetic alopecia. The finding is very important to recognize. Focal atrichia occurring in patients under 30 is worrisome for me as it is associated with a higher risk for progression to more extensive balding.
