Lipschütz Ulcer: A Rare Etiology Among Infants

Area of Science:

• Pediatric Dermatology
• Gynecology

Background:

• Lipschütz ulcer is a rare, self-limited condition characterized by sudden onset of painful, necrotic vulvar or vaginal ulcers.
• It primarily affects sexually inactive adolescent girls and young women, making it extremely uncommon in infants.

Observation:

• An 11-month-old female presented with fever and crying, later found to have ulcerative lesions on the labia majora.
• Extensive testing for infectious etiologies, including herpesvirus, syphilis, HIV, Epstein-Barr virus, cytomegalovirus, and Mycoplasma pneumoniae, yielded negative results.

Findings:

• The patient's condition was diagnosed as Lipschütz ulcer based on exclusion after ruling out other causes.
• The ulcers resolved completely within four weeks with symptomatic treatment, and the patient remained fever-free.

Implications:

• This case underscores the possibility of Lipschütz ulcers in very young children, challenging the typical demographic presentation.
• The diagnosis of exclusion highlights the importance of considering rare conditions even in atypical patient populations.
• The self-limited nature and lack of sexual transmission are crucial for appropriate patient counseling and management.
