Phthirus pubis infestation is a highly infectious parasitic disease, affecting 1.3-4.6% of people globally. However, the coinfestation of P. pubis on the eyelashes and scalp hairs in children is uncommon, and the clinical characteristics and prognosis have not been fully studied. In this retrospective study, we report five pediatric patients diagnosed with eyelash and scalp coinfestation of P. pubis. The samples were obtained after treatment and sent for pathological examination. The demographic and clinical characteristics of the study participants were analyzed in detail. Numerous lice and nits were detectable on the eyelashes and scalp hairs in all enrolled patients. The ages ranged from 2 to 5 years. The duration of onset ranged from 3 to 10 days. The common clinical presentations were itching (100%) and conjunctivitis (60%). Treatment included eyelash and scalp hair trimming to the root (100%) and mechanical removal of the parasites (100%), in addition to topical tobramycin eye ointment (100%) and phenothrin shampoo (80%). Symptoms resolved by a 1-week follow-up. Pediatric P. pubis coinfestation mainly occurs on the eyelashes and temporal scalp in females, and sometimes contact tracing fails to identify the source. Phthirus pubis infestation of eyelashes can be misdiagnosed as blepharoconjunctivitis. Sexually transmitted diseases should be ruled out for patients with P. pubis infestation. Untreated or persistent cases may lead to several serious infections.
阴虱感染是一种高度传染性的寄生虫病，全球发病率为 1.3%-4.6%。然而，儿童睫毛和头皮毛发同时感染阴虱的情况并不常见，其临床特征和预后尚未得到充分研究。在这项回顾性研究中，我们报告了 5 例诊断为睫毛和头皮阴虱共感染的儿科患者。在治疗后采集样本并进行病理检查。详细分析了研究参与者的人口统计学和临床特征。所有纳入患者的睫毛和头皮毛发上均可见大量虱子和虱卵。年龄范围为 2-5 岁。发病时间从 3 天到 10 天不等。常见的临床表现为瘙痒（100%）和结膜炎（60%）。治疗包括睫毛和头皮毛发根部修剪（100%）和寄生虫机械清除（100%），此外还使用妥布霉素眼膏（100%）和扑灭司林香波（80%）。随访 1 周后症状缓解。儿科阴虱共感染主要发生在女性的睫毛和颞部头皮，有时接触追踪无法确定来源。阴虱感染的睫毛可误诊为睑结膜炎。对于阴虱感染的患者，应排除性传播疾病。未治疗或持续存在的病例可能导致多种严重感染。
