The entity known as "juvenile-like (inflammatory/hyperplastic) mucosal polyps of the gastrointestinal tract in neurofibromatosis type 1 (NF1)" was recently proposed, but is not well known. Here, we describe the characteristics of this entity in a surgically resected case. The hemorrhagic 2 × 1 cm-sized polyp was resected from the ascending colon of a 55-year-old male NF1 patient. The polyp was composed of characteristic multiple mucosal protrusions and submucosal elements that included vasculopathic changes. Histologically, this lesion was similar to an inflammatory fibroid polyp rather than juvenile or hyperplastic polyps. This disease could be a distinct entity, and "inflammatory vasculopathic polyp" would be a suitable name.
最近提出了一种名为“1型神经纤维瘤病（NF1）患者胃肠道的幼年样（炎症性/增生性）黏膜息肉”的实体，但目前对此了解不多。在此，我们描述了一例手术切除病例中该实体的特征。从一名55岁男性NF1患者的升结肠切除了一个2×1厘米大小的出血性息肉。该息肉由特征性的多个黏膜突起和包含血管病变改变的黏膜下成分组成。组织学上，该病变类似于炎性纤维瘤性息肉，而非幼年性或增生性息肉。这种疾病可能是一种独特的实体，“炎性血管病变性息肉”可能是一个合适的名称。
