Rare Infantile Furunculosis in a 3-Month-Old Infant: A Diagnostic Challenge

Staphylococcus aureus is a major pathogen responsible for a wide range of skin and soft tissue infections, including impetigo, folliculitis, furunculosis, and abscesses.
We report the case of a 3-month-old infant with a history of prematurity, cesarean delivery, and neonatal pulmonary infection, presenting with erythematous violaceous nodules on the trunk and back, complicated by a cutaneous abscess. The diagnosis of furunculosis was made based on clinical findings and evolution, with favorable outcome under local care and intravenous antibiotics.
This case is notable due to the rarity of furunculosis in infants, underscoring the importance of including it in the differential diagnosis of suppurative nodular lesions such as impetigo, abscesses, and panniculitis. It also highlights the necessity of systematically investigating predisposing factors, including prematurity and neonatal infectious history.
Early recognition and prompt management of bacterial skin infections in infants are essential to ensure accurate diagnosis, appropriate treatment, and optimal outcomes.
