The diagnosis of infiltrative basal cell carcinoma (BCC) can be delayed owing to its often subtle clinical findings. A 90-year-old woman presented with an asymptomatic annular pink plaque on her left shin that was clinically diagnosed as tinea corporis. After years of not responding to topical anti-fungal therapy, biopsies confirmed a diagnosis of infiltrative BCC. We discuss the differential diagnosis of the case, the difficulties in identifying infiltrative BCC, and the pathologic features of infiltrative BCC.
浸润性基底细胞癌（BCC）的诊断常常会因临床症状不明显而延误。一名90岁女性患者左小腿出现无症状的环形粉红色斑块，临床诊断为体癣。经过数年局部抗真菌治疗无效后，活检确诊为浸润性BCC。我们讨论了该病例的鉴别诊断、识别浸润性BCC的困难以及浸润性BCC的病理特征。
