As studies on keratoacanthomas (KAs) within tattoos are scarce, our comprehension on the development of KAs in tattoos remains limited. Notably, existing studies predominantly focus on KAs found in tattoos containing red ink. This study addresses these gaps by documenting two cases of KAs within recently applied black and grey tattoos. The first case, a woman in her mid-40s, presented with two painful hyperkeratotic lesions in the tattooed skin on her left forearm and, notably, one similar simultaneously grown asymptomatic papule outside the tattooed skin. The second case, a man in his early 40s, presented with a painful hyperkeratotic nodule on a tattoo on the right leg. Histopathology showed that the nodules in both patients were compatible with a KA. After discussing therapeutic options, both patients opted for a wait-and-see approach, whereafter, the nodules regressed within months.
由于关于纹身内角化棘皮瘤（KA）的研究稀少，我们对纹身内KA发生发展的理解仍然有限。值得注意的是，现有研究主要集中在含红色墨水的纹身中发现的KA。本研究通过记录两例近期纹的黑白纹身内的KA来填补这些空白。第一例，一名45岁左右的女性，左前臂纹身皮肤出现两个疼痛性角化过度性皮损，值得注意的是，纹身皮肤外同时有一个类似的无症状丘疹也在生长。第二例，一名40岁出头的男性，右腿纹身处出现一个疼痛性角化过度性结节。组织病理学显示两名患者的结节均符合KA。在讨论了治疗方案后，两名患者都选择了观察等待，之后，结节在数月内消退。
