Background: This case report provides the general pediatrician with insight on a unique presentation of an already rare disease. Plastic bronchitis (PB) is an exceedingly rare disease that presents with the formation of casts in the endobronchial tree. This typically occurs in patients with congenital heart defects that have undergone repair, however, it is atypical to be seen in otherwise healthy patients. Influenza A, lymphatic abnormalities, and single ventricle physiology are the only proven causes of PB. Asthma, toxic inhalation, and acute chest syndrome, however, are a few of the many conditions that have been proposed to predispose patients toward developing PB.

喘息的一切都不是哮喘：病例报告

背景：本病例报告为普通儿科医生提供了关于已经罕见疾病的独特表现的见解。塑料性支气管炎 (PB) 是一种极其罕见的疾病，表现为支气管内树管型的形成。这通常发生在患有先天性心脏缺陷且经过修复的患者身上，然而，在其他方面健康的患者中并不典型。甲型流感、淋巴异常和单心室生理学是唯一已证实的 PB 原因。然而，哮喘、中毒性吸入和急性胸部综合征是已提出的使患者易患 PB 的众多疾病中的一小部分。
