BACKGROUND Because most of the US population will consist of nonwhite individuals by the year 2043, it is essential that both physicians and patients are educated about skin cancer in nonwhite persons. OBJECTIVE To update the epidemiology, investigate specific risk factors, and facilitate earlier diagnosis and intervention of keratinocyte carcinoma in nonwhite individuals. METHODS Institutional review board-approved retrospective chart review of all nonwhite patients who had received a biopsy-proven diagnosis of skin cancer at Drexel Dermatology during June 2008-June 2015. RESULTS Squamous cell carcinoma (SCC) was the most commonly diagnosed skin cancer in black and Asian populations, and basal cell carcinoma was the most common skin cancer in Hispanics. Black persons exhibited the majority of their SCC lesions in sun-protected areas, particularly the anogenital area. On average, current smokers received skin cancer diagnoses 12.27 years earlier than former smokers and 9.36 years earlier than nonsmokers. LIMITATIONS Single-center design and interpractitioner variability of skin examination. CONCLUSION The importance of lesions in photoprotected areas in nonwhite individuals should not go overlooked. However, emphasis should also be placed on active examination of sun-protected areas in nonwhite persons and recognition of the relationship between human papillomavirus and genital SCC lesions. Smoking cessation should be integrated in dermatologic counseling of all patients. Interventions tailored to each of these ethnic groups are needed.

非白人个体角质形成细胞癌皮肤癌的危险因素：回顾性分析。

背景技术由于到2043年，美国大多数人口将由非白人组成，因此必须对医生和患者进行有关非白人皮肤癌的教育。目的更新流行病学，调查特定的危险因素，并促进非白人个体角质形成细胞癌的早期诊断和干预。方法2008年6月至2015年6月在Drexel皮肤病学中心接受活检证实的皮肤癌诊断的所有非白人患者，均获得了机构审查委员会批准的回顾性图表审查。结果鳞状细胞癌（SCC）是黑人中最常见的皮肤癌和亚洲人群，基底细胞癌是西班牙裔中最常见的皮肤癌。黑人在阳光充足的地区表现出大部分的SCC病变，尤其是肛门生殖器区域。平均而言，目前的吸烟者被诊断出皮肤癌的时间比以前的吸烟者早12.27年，比不吸烟者早9.36年。局限性皮肤检查的单中心设计和从业者之间的差异。结论非白人个体光保护区病变的重要性不容忽视。但是，也应强调积极检查非白人的防晒区域，并认识人乳头瘤病毒与生殖器SCC病变之间的关系。戒烟应纳入所有患者的皮肤病咨询中。需要针对这些族裔中的每个族裔量身定制的干预措施。比不吸烟者早36年。局限性皮肤检查的单中心设计和从业者之间的差异。结论非白人个体光保护区病变的重要性不容忽视。但是，也应强调积极检查非白人的防晒区域，并认识人乳头瘤病毒与生殖器SCC病变之间的关系。戒烟应纳入所有患者的皮肤病咨询中。需要针对这些族裔中的每个族裔量身定制的干预措施。比不吸烟者早36年。局限性皮肤检查的单中心设计和从业者之间的差异。结论非白人个体光保护区病变的重要性不容忽视。但是，也应强调积极检查非白人的防晒区域，并认识人乳头瘤病毒与生殖器SCC病变之间的关系。戒烟应纳入所有患者的皮肤病咨询中。需要针对这些族裔中的每个族裔量身定制的干预措施。还应强调积极检查非白人的防晒区域，并认识人乳头瘤病毒与生殖器SCC病变之间的关系。戒烟应纳入所有患者的皮肤病咨询中。需要针对这些族裔中的每个族裔量身定制的干预措施。还应强调积极检查非白人的防晒区域，并认识人乳头瘤病毒与生殖器SCC病变之间的关系。戒烟应纳入所有患者的皮肤病咨询中。需要针对这些族裔中的每个族裔量身定制的干预措施。
