Plica neuropathica in severe reactive depression: clinical and trichoscopic features
Abstract
Plica neuropathica (PN), also known as plica polonica, felting, matting or bird's nest hair, is an acquired hair condition in which hair becomes twisted, leading to the formation of a compact mass. Psychiatric disorders are an important etiologic factor for PN. We report a case of PN in a woman with severe reactive depression and present the trichoscopic findings.
