Abstract：
Keratoacanthoma (KA) is a common, low-grade, rapidly growing cutaneous squamous cell carcinoma that presents as an enlarging crateriform nodule, which may spontaneously involute but rarely metastasizes. Immunosuppression, ultraviolet light, viral infection, surgical procedures, and trauma are associated with their development. Overall, tattoo-induced squamous cell neoplasms are infrequently described in the literature. Carcinogenesis is hypothesized to result from trauma caused by the tattooing procedure or a foreign body reaction to the pigment. However, the pathogenesis has not been clearly defined. While most commonly associated with red ink, to date, very few cases of KA forming within black, blue, or multicolored ink tattoos are reported. Herein, we describe a case of KA arising within areas of blue and black pigment in a decorative ink tattoo.
摘要：
角化棘皮瘤（KA）是一种常见的，低档,快速增长的皮肤鳞状细胞癌，表现为扩大的圆形结节，可能自发渐开线，但很少转移。免疫抑制,紫外光,病毒感染,外科手术,创伤与它们的发展有关。总的来说,文献中很少描述纹身诱导的鳞状细胞肿瘤。假设致癌是由纹身程序或异物对色素的反应引起的创伤引起的。然而,发病机制尚未明确。虽然最常见的是红色墨水，到目前为止,很少有在黑色内形成KA的病例，蓝色,或报告了多色墨水纹身。在这里，我们描述了在装饰性墨水纹身中的蓝色和黑色颜料区域内出现KA的情况。
