Keratoacanthomas (KAs) are common skin lesions known for their rapid growth and spontaneous regression. Keratoacanthomas also can occur in sites of prior trauma, such as surgical scars. We report a case of multiple KAs occurring in the site of trauma from a prior surgery and de novo as well as the response to treatment with intralesional methotrexate (MTX).
角化棘皮瘤（KAs）是常见的皮肤病变，以其快速生长和自发消退而闻名。角化棘皮瘤也可发生在先前创伤的部位，如手术疤痕处。我们报告一例在先前手术创伤部位出现多发性角化棘皮瘤以及新发角化棘皮瘤的病例，以及病灶内注射甲氨蝶呤（MTX）的治疗反应。
