Perianal streptococcal dermatitis

A previously healthy 3-year-old boy presented with rectal pain and refusal to sit and defecate over the past 24  h. He had no fever. The perianal region showed a painful circumferential bright erythema with well-demarcated margins (diameter 4 cm) covered with light exudate (Fig. 1). An anal fissure was noted. He had chronic obstipation. There were no close contacts with tonsillitis or impetigo. The rapid a ntigen detection test for group A Streptococcus (GAS) of the perianal lesion showed a positive result (Healgen GAS Rapid Test – Cassette).
