少年喉乳头状瘤(JLP)是一种极为常见的儿童喉赘生性瘤。组织学上虽不是恶性肿瘤,但有2％可转移到气管、支气管,甚至肺实质。过去包括手术切除在内的种种治疗方法常顽固地复发,且切除治疗的过程中有4—64％要作气管切开,即使激光治疗也只能使气管切开减少至2％左右。作者报告一例经转移因子治疗,肺部乳头状瘤明显消退的病例。 Juvenile laryngeal papilloma (JLP) is a very common childhood laryngeal neoplasm. Histologically it is not a malignant tumor, but 2% can be transferred to the trachea, bronchi, or even lung parenchyma. In the past, various treatment methods, including surgical resection, often stubbornly relapsed, and 4 to 64% of the resections required tracheotomy. Even laser treatment can only reduce tracheotomy to about 2%. The authors report one case of treatment with transfer factor and a significant resolution of papilloma in the lung.
