Basal cell carcinoma (BCC) is the most common cancer in humans worldwide. Many highly specific dermoscopic criteria for BCC are well established in the literature. On the contrary, other malignant or benign skin tumors may mimic BCC by exhibiting similar or even the same dermoscopic features and therefore obscuring the diagnosis of BCC in certain situations. We herein report a case of BCC with dermoscopic features of both BCC and desmoplastic trichoepithelioma (DT). We would like to remind of the often neglected differential diagnosis of DT in a lesion with arborizing vessels and otherwise unusual dermoscopic presentation.
基底细胞癌（BCC）是全球人类最常见的癌症。文献中已确立了许多针对BCC的高度特异性皮肤镜标准。相反，其他恶性或良性皮肤肿瘤可能通过表现出相似甚至相同的皮肤镜特征来模仿BCC，因此在某些情况下会模糊BCC的诊断。我们在此报告一例具有BCC和促纤维增生性毛发上皮瘤（DT）皮肤镜特征的BCC病例。我们想提醒大家，在具有树枝状血管和其他异常皮肤镜表现的病变中，DT的鉴别诊断常常被忽视。
