RESUMEN
Tropical skin diseases are infectious conditions influenced by factors such as nutrition, housing, and the environment. Migration patterns have caused these conditions to be seen all around the world, not only in developing countries. Many of these diseases have a different presentation in childhood, which changes the diagnostic approach and management options. In this article, we review some of the most common tropical mycobacterial, protozoan, parasitic, and viral dermatologic conditions in children, including their epidemiologic, clinical, diagnostic, and therapeutic aspects.

Because of travel and migration patterns, tropical skin diseases are now seen all around the world, not just in tropical or developing countries. Nutrition, housing, and environmental factors play an important role in these infectious diseases, so when they appear out of their normal environments, their classic presentation may vary. Tropical diseases can also present differently in childhood, making their recognition, diagnosis, and management a clinical challenge. Health care providers in developed countries need to be familiar with tropical skin diseases and be able to diagnose them in returning travelers or immigrants in order to optimize care. This article aims to review the epidemiologic, clinical, diagnostic, and therapeutic aspects of some of the most common tropical dermatologic conditions in children.

Although contact with domestic cats has been shown to be a risk factor for sporotrichosis in endemic areas, systematic evaluation of apparently unaffected cats as possible reservoirs for infection has not been explored. The goals of this study were to identify the following aspects of sporotrichosis in the endemic area of Abancay, Peru: (i) the overall prevalence of sporotrichosis in the cat population, (ii) the most common site where the fungus can be isolated from these cats, and (iii) whether cats without identifiable skin lesions may be carriers of the fungus in the oral mucosa, nasal mucosa, or nails. One household cat in each of 85 neighborhoods within the endemic area of Abancay, Peru was randomly selected. Oral and nasal swabs, as well as nail clippings were taken from 84 of the cats. In addition, samples from skin lesions that were suspected to be due to sporotrichosis were collected from cats or members of families that owned the pets. Cultures inoculated with two nasal swabs and one set of nail clippings from two different cats yielded Sporothrix schenckii, the identity of which were confirmed by rDNA sequencing. The overall prevalence of Sporothrix schenckii colonization was 2.38% (95% CI 0.41-9.14) in this cat population. None of the skin lesion samples from the cats and only one such sample from a family member were positive for Sporothrix schenckii in culture. These results suggest a role for domestic cats as a possible reservoir for sporotrichosis infection in Abancay.
