Thirty-nine keratoacanthomas from 35 patients have been studied, six of which showed perineural, and one vascular, invasion. Thus far, their aggressive histological behavior has not been paralleled by a similar clinical course. However, continued close follow-up is essential.
对35例患者的39个角化棘皮瘤进行了研究，其中6个显示神经周围浸润，1个显示血管浸润。迄今为止，它们侵袭性的组织学表现并未伴有类似的临床病程。然而，持续密切随访至关重要。
