The main causative organism of balanoposthitis in sexually active adolescents is reportedly the group B hemolytic streptococcus. While cases of balanoposthitis caused by group A streptococcal infection in children have been reported, their occurrence in the adolescent age group is relatively rare. We describe a case of balanoposthitis caused by Streptococcus pyogenes (group A streptococcus) in a 31-year-old man who presented to the hospital with complaints of pain and swelling in his penile foreskin for the past 6 days. The patient was treated successfully by performing a ventral incision on the foreskin and administering effective antimicrobial therapy involving amoxicillin 750 mg/day. Group A beta-hemolytic Streptococcus pyogenes should also be considered a causative organism in the differential diagnosis, while managing a patient with balanoposthitis.
