Abstract

A 62-year-old woman presented with diffuse net-like hyperpigmentation for 1 year. Dermoscopic examination showed a pseudonetwork pattern of dark brown-gray dots which is characteristic feature of lichen planus pigmentosus. There is confirmed diagnosis by histopathological findings. In this patient, the pigmented lesions are predominantly confined to intertriginous and flexural areas called lichen planus pigmentosus inversus (LPPI). She also had a total loss of eyebrows and band-like scarring alopecia in the frontotemporal hairline which was consistent with frontal fibrosing alopecia (FFA). Here we report a patient presented with LPPI coexisting with FFA.
