“…Other authors however have noted that EDP can occur without marginal erythema [4,5]. Bhutani and his colleagues described similar hyperpigmented macules over the flexures and photoexposed areas in 40 Indian patients, about a third of whom had associated features of lichen planus on clinical evaluation and histopathological examination [6]. These entities were subsequently labeled as "lichen planus pigmentosus (LPP)".…”

“…Lichen planus pigmentosus (LPP) was first described by Bhutani et al 1 , and this a rare variant of lichen planus, and LPP appears as mottled or reticulated hyperpigmented, dark brown macules or papules on the sun exposed areas and flexural folds 2,3 . Linear lichen planus, which shows a linear distribution following Blaschko's lines, is considered a subtype of lichen planus [3][4][5] .…”

Lichen planus pigmentosus (LPP) is chronic pigmentary disorder that shows diffuse or reticulated hyperpigmented, dark brown macules on the sun-exposed areas such as the face, neck and other flexural folds. Clinically, it is different from classical lichen planus because LPP has a longer clinical course and it manifests with dark brown macules. In case of LPP, involvement of the scalp, nail or mucosal area is rare. The histopathological findings of the lesions show an atrophic epidermis, the presence of melanophages and a vacuolar alteration of the basal cell layer with a sparse lymphohistiocytic lichenoid infiltration. Although there have been a few reports of LPP, there have only 3 cases of linear LPP along the lines of Blaschko in the Korean dermatologic literature. Our patient had lesions on the neck and chin with a linear pattern. In this report, we describe a very rare case of LPP with a linear distribution related to Blaschko's lines on the neck and chin areas.

“…In fact, while Bhutani et al [1] stressed that LPP was never localized in the oral mucosa. Laskaris et al [5] described a case of LPP of the oral mucosa.…”
