RESUMO
La dermatitis perianal estreptocócica es una entidad bien definida. Se caracteriza por eritema de límites precisos, prurito, dolor rectal y heces teñidas de sangre, en ausencia de síntomas generales. Afecta fundamentalmente a niños entre los 6 meses y los 10 años. A menudo es subestimada y tratada inapropiadamente. Presentamos tres casos; creemos de interés su comunicación por su relativa escasa frecuencia y su diagnostico tardío, posiblemente en relación con un bajo índice de sospecha. En dos pacientes se asoció con balanopostitis, circunstancia que podía hacer sospechar abuso sexual
Perianal streptococcal dermatitis is a well-described entity, typically presenting as a perianal rash accompanied by perianal itching, pain, and/or rectal bleeding. It primarily occurs in children between six months and 10 years of age, and is often misdiagnosed and treated inappropriately. We describe three cases of perianal streptococcal dermatitis in which group A beta-hemolytic streptococcus was isolated from the perianal area. This communication is of, great interest, we believe, because of its relative little frequency, its delayed diagnostic, possibly in relation to a low level suspicion, along with the association in two of the cases with balanopostitis, circumstance that could arise the suspicion of abuse
