A Case of Lipschütz Ulcers in a 13-Year-Old Girl With PFAPA Syndrome.

Lipschütz ulcers (LU), also known as reactive non-sexually related acute genital ulcerations, are an uncommon condition that primarily affects sexually inactive girls under the age of 20 years. In this report, we describe a 13-year-old female with a past medical history of periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) in early childhood who presented to the emergency department (ED) for sudden onset of genital ulcerations and labial swelling. Based on her clinical presentation, negative primary infectious workup, unresponsiveness to broad-spectrum antimicrobials, and concurrent viral infection, she was diagnosed with LU.
