Frontal Fibrosing Alopecia Associated with Lichen Planus Pigmentosus – Report of 2 Cases

The document reported two cases of the rare association between frontal fibrosing alopecia and lichen planus pigmentosus in two female patients, aged 59 and 76, with darker skin tones. Both patients exhibited marginal fronto-temporal hair thinning and brownish hyperpigmentation on the face, neck, and trunk. Frontal fibrosing alopecia, a scarring alopecia variant of lichen planopilaris, was first described in 1994 and is characterized by progressive hairline recession. Dermoscopy was highlighted as a crucial diagnostic tool to differentiate it from other conditions. Lichen planus pigmentosus, another variant, is uncommon and primarily affects women with skin types III and IV in their 30s and 40s.
