Although basal cell carcinoma (BCC) accounts for as high as 75% of all malignant skin tumors, its metastatic rate is only 0.1%. Predisposing factors for metastasis are generally thought to be: 1. a head and neck primary BCC; 2. a long standing lesion; 3. deep local invasion with ulceration. This paper presents a patient with metastatic BCC with a history of other malignancies and probable immune system compromise. These factors should also alert the clinician to the possibility of metastatic BCC.
尽管基底细胞癌（BCC）占所有恶性皮肤肿瘤的比例高达75%，但其转移率仅为0.1%。转移的诱发因素通常被认为是：1. 头颈部原发性基底细胞癌；2. 长期存在的病变；3. 伴有溃疡的深部局部浸润。本文介绍了一名患有转移性基底细胞癌的患者，该患者有其他恶性肿瘤病史且可能存在免疫系统受损情况。这些因素也应提醒临床医生注意转移性基底细胞癌的可能性。
