    OBJETIVO: Avaliar a prevalência de lesões cutâneas actínicas em portadores de carcinoma basocelular do segmento cefálico. MÉTODOS: Foi conduzido estudo tipo caso-controle. Os casos, constituídos por pacientes com carcinoma basocelular sólido, primário, menor que dois centímetros, no segmento cefálico; e controles, por pacientes com outras dermatoses. Foram analisadas variáveis constitucionais, comportamentais e lesões actínicas. RESULTADOS: Avaliaram-se 120 casos e 360 controles. Mílio facial (OR = 2,3), leucodermia puntacta de membros superiores (OR = 2,9) e cutis romboidalis nuchae (OR = 1,8) associaram-se à neoplasia independentemente das demais variáveis, sugerindo um fenótipo de risco. Houve ainda associação com fenótipos claros, genética familiar e exposição solar cumulativa. Queimadura solar, tabagismo e alcoolismo não foram identificados como fatores de risco. O uso de fotoprotetores não evidenciou proteção; porém, o grupo controle era composto por pacientes dermatológicos, aos quais são indicados fotoprotetores regularmente. CONCLUSÃO: Lesões actínicas foram mais prevalentes em portadores de carcinoma basocelular sólido do segmento cefálico que em controles, especialmente mílio, cutis romboidalis nuchae e leucodermia puntacta, independentemente dos demais fatores de risco conhecidos.OBJECTIVE: To evaluate the prevalence of actinic skin lesions in patients with basal cell carcinoma of the head. METHODS: A case-control study was carried out. Cases were patients with primary, solid basal cell carcinoma of the head, less than two centimeters in diameter; and as controls, patients with other dermatoses. Constitutional and behavioral variables were analyzed, as well as actinic lesions. RESULTS: One hundred twenty cases and 360 controls were evaluated. Facial milia (OR = 2.3), leukoderma punctata of the upper limbs (OR = 2.9), and cutis rhomboidalis nuchae (OR = 1.8) were associated with neoplasms regardless of other variables, suggesting a risk phenotype. There was also association with light hair and eye color phenotypes, family genetics, and cumulative sun exposure. Sunburn, smoking, and alcoholism were not identified as risk factors. The use of sunscreens showed no evidence of protection; however, the control group consisted of dermatology patients who are often prescribed sunscreens. CONCLUSION: Actinic lesions were more prevalent in patients with solid basal cell carcinoma of the head than in controls, especially milia, cutis rhomboidalis nuchae, and leukoderma punctata, regardless of other known risk factors

    A incidência do carcinoma basocelular vem aumentando em todos os países. Realizou-se estudo ecológico de 5169 laudos de carcinoma basocelular, da FMB-Unesp, entre janeiro/1999 e dezembro/2009. O incremento médio da incidência para o período foi de 90,6%, projetando-se um diagnóstico para cada 15 pacientes encaminhados à dermatologia. Tal tendência se manteve, mesmo quando indexada pelo número de laudos histopatológicos, movimento hospitalar, atendimentos da dermatologia e população de Botucatu.The incidence of basal cell carcinoma is increasing worldwide. An ecological study was conducted using the pathology reports from 5169 cases of basal cell carcinoma diagnosed at the Botucatu School of Medicine, Universidade Estadual Paulista Julio de Mesquita Filho (UNESP) between January 1999 and December 2009. The mean increase in the incidence of basal cell carcinoma over this period was 90.6%, suggesting that one case of basal cell carcinoma could be expected for every 15 patients referred to dermatology. This trend was also found when the incidence was indexed according to the absolute number of histopathology exams, the total number of hospital consultations, the total number of dermatological consultations and the population of the town of Botucat
