Abstract

Bowen's disease is a type of squamous cell carcinoma in situ of the skin. The pigmented form is rare and represents less than 2% of cases. We report a case of a 74-year-old black man with a blackened and asymptomatic leg injury for about 6 months. Clinically, and under dermatoscopy, the injury was suggestive of melanoma or melanoacanthoma, and a definitive diagnosis was made by histopathological examination.

摘要

鲍温病是一种皮肤原位鳞状细胞癌。色素沉着型较为罕见，占病例不到2%。我们报告一例74岁黑人男性病例，其腿部有一处变黑且无症状的损伤，持续约6个月。临床及皮肤镜检查时，该损伤提示为黑色素瘤或黑素棘皮瘤，最终通过组织病理学检查确诊。
