Frontal fibrosing alopecia associated with cutaneous lichen planus in a premenopausal woman

A 45-year-old premenopausal woman presented with frontal fibrosing alopecia (FFA) and later developed cutaneous lichen planus, marking the first reported case of FFA associated with cutaneous lichen planus. The patient exhibited progressive hair loss on the frontoparietal scalp and eyebrows, with histopathology confirming FFA. Subsequent development of pruritic papules on the wrists and feet led to a diagnosis of cutaneous lichen planus. Treatment with topical corticosteroids stabilized the conditions. This case supports the notion that FFA is a variant of lichen planopilaris (LPP).
