Acknowledging the pseudo “fringe sign” in frontal fibrosing alopecia has diagnostic and prognostic implications

To the Editor: A frontal band of scarring alopecia with eyebrow involvement in postmenopausal women (ie, frontal fibrosing alopecia [FFA]) evolved from a "recently described disease" to the status of "a growing epidemic" in less than 2 decades. Since the first report by Kossard,1 additional features and variants not contemplated in the original description have been incorporated into the clinical picture. For such, I read with great interest the paper by Rossi et al reporting 3 unusual clinical patterns of FFA.
