Lichen planus pigmentosus (LPP) is a distinctive variant of lichen planus described for the first time in 1974. A wide range of presentations and distribution patterns have been reported, mainly presenting as dark brown hyperpigmented macules and patches, typically involving sun-exposed areas such as the face, neck, and flexural folds. It is more common in dark-skinned patients with a female predominance. Infrequently, LPP may present as a Blaschkoid distribution, with only a few cases reported in the medical literature. We report an unusual case of LPP that developed with a unilateral Blaschkoid distribution on the left side of the trunk in a 32-year-old female following weight reduction surgery.
色素性扁平苔藓（LPP）是1974年首次描述的扁平苔藓的一种独特变体。已经报道了多种表现形式和分布模式，主要表现为深褐色色素沉着斑和斑片，通常累及面部、颈部和屈侧褶皱等暴露于阳光的部位。在女性占主导的深色皮肤患者中更为常见。色素性扁平苔藓很少呈Blaschkoid分布，医学文献中仅有少数病例报道。我们报告了一例不寻常的色素性扁平苔藓病例，一名32岁女性在减重手术后，左侧躯干出现单侧Blaschkoid分布。
