Keratoacanthoma centrifugum marginatum (KCM) is a rare variant of keratoacanthoma (KA). It is characterized by a progressive peripheral expansion and central healing leaving atrophic scar. It is sometimes confused with squamous cell carcinoma (SCC) both clinically and histopathologically. We here report a case of KCM over the extensor aspect of the right forearm in a 57-year-old man with an abnormal looking scar.

离心性边缘性角化棘皮瘤（KCM）是角化棘皮瘤（KA）的一种罕见变异型。其特征为渐进性的外周扩展和中央愈合并遗留萎缩性瘢痕。它在临床和组织病理学上有时会与鳞状细胞癌（SCC）相混淆。我们在此报告一例57岁男性右前臂伸侧出现异常外观瘢痕的离心性边缘性角化棘皮瘤病例。
