Frontal fibrosing alopecia and lichen planopilaris in HLA-identical mother and daughter.

Frontal fi brosing alopecia (FFA) is a lymphocyte-mediated scarring alopecia thought to be a variant of lichen planopilaris (LPP). We present a 67-year-old woman with frontal fi brosing alopecia whose daughter was diagnosed to have lichen planopilaris. Both patients had identical human leukocyte antigen (HLA) D types, supporting a phenotypical relationship between the two clinical entities. Interestingly, our patient also had of autoimmune chronic atrophic gastritis, a previously unreported association.
