Case Series of Frontal Fibrosing Alopecia and Fibrosing Alopecia in a Pattern Distribution: Is There a Familial Correlation?

Introduction: Frontal Fibrosing Alopecia (FFA) and Fibrosing Alopecia in a Pattern Distribution (FAPD) are two distinct entities of cicatricial pattern hair loss that share histological features of perifollicular lichenoid inflammation associated with concentric fibrosis. Although the pathophysiology of FFA and FAPD are still unknown, recently published reports of familial cases indicate a possible genetic correlation.

Case Presentation: We report 6 cases of familial alopecia composed of mothers and daughters: five with FFA and one with FAPD.
