Plica polonica (plica neuropathica) is an uncommon entity characterized by irreversible twisting and matting of hair resulting in a hard impermeable mass of keratin. Although the exact mechanism is not fully understood, it has been attribute to longitudinal splitting or weathering of hair shaft due to vigorous friction and frequent use of harsh shampoos and harsh cleansers and/or due to keeping long hair with poor hair care or neglect, parasitic infection. We describe an unusual case of plica polonica occurring in a patient of lung adenocarcinoma on chemotherapy and review the literature. Anagen effluvium due to chemotherapy (paclitaxel and carboplatin) and use of an uncustomary shampoo by the patient are the causative factors for matting of the hair.
波兰发辫(神经病理性发辫)是一种罕见的病症,其特征为毛发不可逆的扭曲和缠结,形成坚硬且不透水的角蛋白团块。尽管确切机制尚未完全明确,但它被认为是由于剧烈摩擦、频繁使用刺激性洗发水和清洁剂,以及/或者因头发护理不善或疏于打理而留长发、寄生虫感染导致毛干纵向裂开或受损所致。我们描述了一例在接受化疗的肺腺癌患者中发生的波兰发辫罕见病例,并对相关文献进行了综述。化疗(紫杉醇和卡铂)导致的生长期脱发以及患者使用了不合适的洗发水是头发缠结的致病因素。
