[Perianal streptococcal dermatitis in children].

Perianal dermatitis caused by Streptococcus pyogenes (beta-haemolytic Lance-field group A) was diagnosed in four children, three boys aged I, 6 and 8 years and a girl aged 2 years. Perianal itching in children is most frequently attributed to enterobiasis (Enterobius vermicularis); fissures due to scratching can complicate this situation. Perianal streptococcal dermatitis can effectively be treated with oral penicillin, in combination with local antibiotic application (fucidin, mupirocin).
