Atypical and unusual locations of psoriasis are very frequent. However, localized linear psoriasis is rare, with few cases described in the literature. It is characterized by a linear distribution of psoriasis lesions along Blaschko lines. We report the case of a three years old child, who presented unilateral erythematous scaly plaques arranged along Blaschko lines in the left hemithorax, with no associated symptoms and no lesions in other parts of the body. The differentiation of linear psoriasis from other linear dermatoses is not easy. The combination of a thorough history, a careful examination of the skin and histopathology are essential to ensure the correct diagnosis and appropriate treatment.
银屑病的非典型和罕见部位非常常见。然而，局限性线状银屑病很少见，文献中报道的病例较少。其特征是银屑病皮损沿布氏线呈线状分布。我们报告一例3岁儿童病例，该患儿左半胸沿布氏线出现单侧红斑鳞屑性斑块，无相关症状，身体其他部位无皮损。将线状银屑病与其他线状皮肤病相鉴别并不容易。详细的病史、仔细的皮肤检查和组织病理学检查相结合对于确保正确诊断和恰当治疗至关重要。
