Basal cell carcinoma (BCC) is the most common malignancy in whites, but it rarely occurs in dark persons.
To report a BCC on the hairy scalp of an Asian Indian female with no obvious risk factors except previous scalp trauma.
We review the English literature concerning BCC in Indians, and compare this with data for North American blacks and whites; and reports of BCC arising in areas of prior trauma.
RESULTS/CONCLUSION: Skin cancer accounts for 1-2% of malignancies in blacks and Indians, compared with one-third of neoplasms in whites. BCC comprises 75% of skin cancers in whites, but squamous cell carcinoma represents 60-65% of skin cancers in blacks and Indians. Although most BCCs occur in sun-exposed areas in whites, blacks, and Indians, a significant percentage also develop in photoprotected areas. Trauma may be a significant risk factor for BCC, either with actinic damage or alone, as in our case.
基底细胞癌（BCC）是白人中最常见的恶性肿瘤，但在肤色较深的人群中很少发生。
报告一例亚洲印度女性毛发性头皮基底细胞癌，除既往头皮外伤外无明显危险因素。
我们查阅了有关印度人基底细胞癌的英文文献，并将其与北美黑人和白人的数据以及先前创伤部位发生基底细胞癌的报告进行比较。
结果/结论：皮肤癌在黑人和印度人中占恶性肿瘤的1%-2%，而在白人中占肿瘤的三分之一。基底细胞癌在白人皮肤癌中占75%，但在黑人和印度人皮肤癌中，鳞状细胞癌占60%-65%。尽管大多数基底细胞癌发生在白人、黑人和印度人的阳光暴露部位，但也有相当比例发生在防晒部位。创伤可能是基底细胞癌的一个重要危险因素，如我们病例中，可能伴有光化性损伤或单独作用。
