Keratoacanthoma centrifugum marginatum (KCM) is a rare variant of keratoacanthoma (KA), characterised by a progressively expanding tumour with a lack of spontaneous remission and significant scarring. KCM has been reported previously in less than 50 cases worldwide. We present the case of a large solitary KCM on the right shin of a 71-year-old woman. This was treated successfully with oral acitretin for 16 months with sustained remission at 24 months. Our case provides further supporting evidence for acitretin as a useful treatment for KCM to induce remission, prevent extensive surgery and minimise destructive scarring.
离心性边缘性角化棘皮瘤(KCM)是角化棘皮瘤(KA)的一种罕见变体,其特征是肿瘤逐渐扩大,缺乏自发缓解且有明显瘢痕形成。此前全球报道的KCM病例不足50例。我们报告了一名71岁女性右小腿出现的一个巨大孤立性KCM病例。该病例口服阿维A治疗16个月,24个月时持续缓解,治疗成功。我们的病例为阿维A作为治疗KCM以诱导缓解、避免广泛手术并使破坏性瘢痕最小化的有效治疗方法提供了进一步的支持证据。
