Abstract: 【Abstract】 Congenital triangular alopecia is a kind of non-inflammatory and non-cicatricial alopecia, and most cases develop this disease at the ages of 2 - 9 years. The pathogenesis of congenital triangular alopecia is still unclear, and there is a lack of effective treatments. Congenital triangular alopecia is rather liable to be misdiagnosed and erroneously treated, and dermoscopy helps confirm the diagnosis. This review summarizes the progress in the epidemiology, pathogenesis, clinical diagnosis, and treatment of congenital triangular alopecia.
