Rapidly progressive diffuse fibrosing alopecia

Generally, cicatricial alopecias are relentlessly and slowly progressive. We describe clinical and histologic features of rapidly progressive cicatricial alopecia in a young man, with overlapping features of frontal fibrosing alopecia (FFA), lichen planopilaris (LPP), fibrosing alopecia with a pattern distribution (FAPD), and cicatricial pattern hair loss (CPHL), suggesting that these conditions may exist along a spectrum.
