We describe a healthy 11-year-old girl, who presented with fever and a painful vulvar ulcer associated with erythematous tonsillitis. Throat swab test for Group A Streptococcus (GAS) was positive. She was treated with amoxicillin. Further investigation was negative, including Herpes Simplex virus DNA from ulcer swab and serology for Epstein-Barr virus, cytomegalovirus and Mycoplasma pneumoniae. Antistreptolysin O titre was high. The ulcer healed in 2 weeks, with no recurrence in a 1 year follow-up period. The association of LU with GAS tonsillitis is very rare.
