Recurrent Erysipelas Caused by Group B Streptococcus Organisms

• Group B β-hemolytic streptococcus (GBS) has emerged as a major cause of neonatal infections. Serious GBS infections in adults occur most frequently when predisposing illness is present. Recurrent erysipelas caused by GBS is reported in a woman who had chronic lymphedema after a radical hysterectomy and radiation therapy. Type III GBS was identified from cultures of vulvar vesicles, vaginal mucosa, and blood. Prophylactic penicillin V potassium therapy prevented further episodes of erysipelas. Group B β-hemolytic streptococcus should be considered a possible cause of erysipelas or cellulitis. ( Arch Dermatol 116:798-799, 1980)
