A total of 9,955 schoolchildren aged 6-16 years have been examined in a tropical region. The prevalence of @entity272 varied from 21 to 87% in the municipalities surveyed. The most common dermatoses were @entity9583 (prevalence 50%), nevi (16.8%), @entity14937 (13.2%), @entity6793 (12.2%), @entity9585 (9.9%), @entity4013 (6.2%), @entity1800 (6.2%), @entity1908 (3.0%) and @entity5477 (2.7%). The prevalence of @entity3136 , @entity45423 , @entity7553 , @entity25118 , @entity27301 , ephelides and @entity29021 is lower but still relatively high. Females had higher rates of @entity9583 and males higher prevalence of @entity9585 . The prevalence of @entity14937 , @entity8205 and @entity1908 was similar in males and females. @entity14663 , macular @entity8205 and especially @entity14937 tended to increase with age. @entity1201 is hyperendemic in the surveyed area and its rate in the schoolchildren examined was 0.08%. Population movement (urbanization), socioeconomic situation, living conditions, promiscuity, and lack of hygiene may be the cause of such high prevalence and of association of two or more @entity272 . Climatic conditions might have enhanced the prevalence of certain dermatoses ( @entity14937 , @entity4013 , @entity25118 , @entity7553 , @entity45423 ).
