Abstract：
BACKGROUND: Keratoacanthomas (KAs) following laser treatment are a rare, but well-described entity.
OBJECTIVE: Herein, we describe a case of eruptive keratoacanthoma (KA) following laser resurfacing treatment and aim to better characterize laser-associated KAs.
METHODS: A literature search was performed on PubMed reviewing laser-associated KAs including various characteristics: epidemiology, history of skin cancer, location, and number, type of laser, as well as the management and outcome.
RESULTS: Fractional ablative was the most common type of laser triggering KAs, and most cases presented within the first month following treatment. The majority of cases of laser-induced KA had a prior history of a malignant or premalignant skin neoplasm. Laser-induced KAs were treated using modalities similar to KAs arising in other contexts.
CONCLUSIONS: Clinicians need to be knowledgeable and prepared to understand, and manage complications following laser treatments, as rare as they may be, including KAs.

摘要：
背景：激光治疗后的角膜棘皮瘤（KAs）很少见，而是描述良好的实体。
目的：在此，我们描述了激光表面修复治疗后发疹性角化棘皮瘤（KA）的病例，旨在更好地表征激光相关的KAs。
方法：对PubMed进行了文献检索，回顾了激光相关的KAs，包括各种特征：流行病学，皮肤癌病史,location,和数量,激光类型,以及管理和结果。
结果：分数烧蚀是最常见的激光触发KAs类型，大多数病例在治疗后的第一个月内出现。大多数激光诱导的KA病例都有恶性或癌前皮肤肿瘤的病史。使用与其他情况下出现的KAs相似的方式处理激光诱导的KAs。
结论：临床医生需要知识渊博，并准备好理解，并控制激光治疗后的并发症，尽管它们很罕见，包括KAs。
