The term “juvenile-like (inflammatory/hyperplastic) mucosal polyps” (JLIHMP) has been recently introduced to describe a spectrum of polypoid lesions in patients with neurofibromatosis type 1 (NF-1). Due to the scarce number of reported cases and histopathological similarities with entities such as sporadic/syndromic juvenile polyps or inflammatory fibroid polyps, this entity remains a subject of debate. We describe herein a case of multiple JLIHMPs in a patient with NF-1, and we document the presence of low-grade dysplasia within one of these polyps.

与上皮发育不良相关的 1 型神经纤维瘤病中的炎症/幼年样息肉

最近引入术语“幼年型（炎症/增生性）粘膜息肉”（JLIHMP）来描述 1 型神经纤维瘤病（NF-1）患者的一系列息肉样病变。由于报告病例数量稀少，且组织病理学与散发性/综合征性幼年息肉或炎性纤维瘤息肉等实体相似，因此该实体仍然是一个争论的话题。我们在此描述了一名 NF-1 患者体内存在多个 JLIHMP 的病例，并且我们记录了其中一个息肉内存在低度不典型增生。
