Phthiriasis palpebrarum is an infestation of the eyelashes caused by the louse Pthirus pubis (Linnaeus, 1758). We report a case of phthiriasis palpebrarum in a 6-year-old girl, which was initially misdiagnosed as allergic blepharoconjunctivitis. Parasites and their nits were found adhering to the eyelashes and eyelids of her right eye as well as scalp hairs. No abnormality was found in the left eye. The histopathology exam revealed the presence of adults and eggs of Pthirus pubis. We mechanically removed all the eyelashes of the right eye at their base, with lice and nits. The scalp was shaved and washed with phenothrin shampoo. No recurrence was found during 3 months of follow-up. Removal of the eyelashes, cutting of scalp hairs, and phenothrin shampoo may be effective in treating phthiriasis palpebrarum. In cases of blepharoconjunctivitis, eyelids and eyelashes should be carefully examined by slit lamp to avoid misdiagnosis.
睑部阴虱病是由耻阴虱（林奈，1758年）引起的睫毛感染。我们报告一例6岁女孩的睑部阴虱病，最初被误诊为过敏性睑结膜炎。在她右眼的睫毛、眼睑以及头皮毛发上发现了寄生虫及其虱卵。左眼未发现异常。组织病理学检查显示存在耻阴虱的成虫和虫卵。我们在睫毛根部机械性地拔除了右眼所有带有虱子和虱卵的睫毛。剃掉了头皮毛发并用氯菊酯洗发水清洗。在3个月的随访期间未发现复发。拔除睫毛、剪掉头皮毛发以及使用氯菊酯洗发水可能对治疗睑部阴虱病有效。对于睑结膜炎病例，应使用裂隙灯仔细检查眼睑和睫毛，以避免误诊。
