Lipschütz Ulcer in a 10-Year-Old Girl Following Pharyngotonsillitis: Case Report of a Rare Cause of Acute Genital Ulceration in Pediatrics.

Lipschütz ulcers, also known as non-sexually acquired acute genital ulcers, are rare lesions that primarily affect adolescent and prepubertal females. Their sudden onset, severe pain, and dramatic appearance can be alarming, often mimicking infectious or autoimmune diseases. A 10-year-old girl presented with severe perineal pain, dysuria, and fever following an episode of pharyngotonsillitis. Examination revealed vulvar ulcers. A diagnosis of Lipschütz ulcers associated with pharyngotonsillitis was established. Supportive therapy led to gradual improvement. This case illustrates the diagnostic challenges of acute vulvar ulcers in pediatric patients and highlights the importance of recognizing Lipschütz ulcers to avoid unnecessary treatments. Although rare, Lipschütz ulcers should be considered in the differential diagnosis of acute genital ulcers in children, especially following systemic illness.
