title: Perianal streptococcal dermatitis associated with guttate psoriasis and/or balanoposthitis: a study of five cases.
abstract: Perianal streptococcal dermatitis (PSD) is a recently described cutaneous entity caused by group A beta-hemolytic streptococci. It is characterized by perianal erythema, sometimes associated with functional disturbances. We describe four children (2 boys, 2 girls) who had acute guttate psoriasis and also PSD. One of these patients also had balanoposthitis. A fifth patient experienced an association of PSD and balanoposthitis without psoriasis. To our knowledge, the association between guttate psoriasis and PSD has only been reported in five children, and the one with balanitis has not been previously reported.
