A 24-year-old female presented with complaints of asymptomatic dark discolouration of face and flexures of 1-month duration. There was no history of drug use or cosmetic application. Examination revealed hyperpigmented macules involving face, trunk and flexures [Figure 1]. Clinical diagnosis of lichen planus pigmentosus (LPP) was made, which was confirmed on histopathology. Dermoscopy (polarised light, 10×, Heine Delta 20) shows diffuse brown background, hem-like pattern of pigment, grey coloured dots and globules and perifollicular pigment deposition [Figure 2].

LPP is a variant of lichen planus characterised by hyperpigmented macules in sun-exposed areas and flexures, and such a condition is seen most commonly in Indian patients.[1] Dermoscopy of lichen planus is characterised by presence of white crossing line on dull red background, corresponding to Wickham striae and presence of peripheral dotted vessels.[2] Dermoscopic examination of LPP shows absence of Wickham striae and vascular features. It is characterised by the presence of pigment pattern like slate grey-to-blue dots and globules, perifollicular and peri-eccrine pigment deposition. Hem-like pigment pattern has also been described, and background colour on dermoscopy is brown.[3],[4],[5] Dermoscopy can be used to differentiate LPP from other facial melanoses like melasma and pigmented contact dermatitis. Pigmented contact dermatitis on dermoscopy shows regular distribution of brown-to-grey coloured dots and globules [Figure 3]. It can be used as an adjunct to histopathology, when the patient is not willing to undergo biopsy. With an increase in available literature and the widespread use of dermoscopy, it will be possible to differentiate various facial melanoses on the basis of dermoscopic features confidently.
