Abstract

Lichen planus pigmentosus (LPP) is a rare clinical variant of the lichen planus. It presents with pigmented, dark brown macular lesions on the flexural or sun exposed regions. Linear LPP is presented with hyperpigmented lesions along the lines of Blaschko. To the best of our knowledge, there are a few cases of linear LPP which have been reported in the literature. In our case report, we present a female Turkish patient with unilateral linear LPP that manifested as asymptomatic brown macular lesions, distributed along the lines of Blaschko between the middle part of the left gluteal region and the left calf.

色素性扁平苔蘚是扁平苔蘚的一種罕見臨床變異型,呈現為在皺摺位或日光暴露位置的色素性(暗棕黃色)斑狀皮損。而線狀色素性扁平苔癬則呈現沿著布拉許口氏線的色素沉著病變。據我們所知,文獻曾報導過少數線狀色素性扁平苔癬的病例。在我們的病例報告中,我們提出一個女性土耳其患者的單側線狀色素性扁平苔癬,表現為無症狀的棕色斑狀皮損,沿著布拉許口氏線分佈由左邊臀部中間直至左小腿。
