Tinea capitis favosa due to Trichophyton schoenleinii infection, or favus, is typically a childhood disease but can persist in adult age. It is exceptional in Europe but always endemic in some regions of the world. The classic lesion is the "scutula", a concave, cup-shaped yellow crust centrally pierced by a hair. The peculiar type of hair invasion (endothrix favic) contributes to the chronic course of favus into adulthood (without healing at the puberty), with scarring alopecia due to lack of treatment. We report a case of tinea capitis favosa in a 43-year-old-woman, probably caused by braids with extension hair at Kinshasa. Systemic terbinafine allowed complete resolution of the disease within 6 months
