title: Lancefield group G Streptococcus dysgalactiae subsp. equisimilis: an unusual aetiology of perianal streptococcal dermatitis acquired from heterosexual oral-anal intercourse.
abstract: Perianal streptococcal dermatitis (PSD) is an uncommon superficial cutaneous infection of the perianal area, almost exclusively described in children and mainly caused by group A streptococci. We report here a case of PSD caused by Streptococcus dysgalactiae subsp. equisimilis, Lancefield group G, in an adult man due to heterosexual oral-anal sexual contact.
