Management of Fournier's gangrene in a newborn: A rare case report and literature review

Introduction: Fournier's gangrene (FG) in neonates is less common than in adults, but this case can lead to a poor prognosis. FG is a disease of the genital, perianal, and perineal areas characterized by necrotizing infections. Here, we report a case of a 24-day-old male infant diagnosed with Fournier's gangrene involving the scrotum. Case presentation: The patient presented with scrotal swelling, fever, erythema, and insect bites on the penile tip that had gradually extended to the proximal area and bilateral scrotum. On physical examination, indurated grayish and blackish-brown scrotal skin with sharp distinction from the surrounding normal skin, erythema, purulence, ulceration, and necrotic tissue were observed. Abdominal X-ray and scrotal ultrasonography revealed gaseous distension of the scrotal region, free fluid on bilateral testes, and enlargement of bilateral testicles. Immediate surgical debridement, along with broad-spectrum antibiotics, was initiated, and a microbiological culture identified the presence of Pseudomonas aeruginosa. The patient demonstrated the completed healing of the surgical wound after thirty days of surgical intervention. Discussion: Fournier's gangrene in neonates is a sporadic case. Our patient presented with multiple predisposing factors, including insect bites and poor hygiene, underscoring the need for heightened clinical suspicion in vulnerable populations. Prompt recognition and intervention are critical, given the rapid progression of FG. Conclusion: This case underscores the importance of timely diagnosis and early initiation of surgical and medical interventions in neonatal Fournier's gangrene, particularly in cases involving the scrotum.
