Necrotizing fasciitis after scrotum skin injury in an infant A case report

Rationale: Necrotizing fasciitis (NF) is a life-threatening situation that is rare in children, especially infants, and early diagnosis is challenging. Timely identification and broad-spectrum antibiotic and supportive treatment before surgical debridement are very important for survival and may reduce scar formation. Patient concerns: A previously healthy 4-month-old infant was admitted to our pediatric intensive care unit (PICU) with a history of fever and cough for 5 days and extreme swelling of the scrotum for one day. Necrotic-like tissue without margins appeared on his scrotum and perineum in 24 hours. Diagnosis: NF was suspected, and the patient soon developed shock. The patient underwent surgical debridement after his condition stabilized. Pathological analysis confirmed the diagnosis of NF. Intervention: Broad-spectrum antibiotic, immediate fluid resuscitation, assistant ventilation, and vasoactive drugs were administered. Surgical debridement and autologous split-thickness skin grafting were performed. Outcomes: The wound recovered well after 2 months. Ultrasound revealed normal testicles, and no anorectal injury was found. Lessons: Close clinical monitoring and timely treatment of skin injuries in sick children are very important. Sufficient antibiotic administration and supportive treatment before surgical debridement are crucial for survival from NF.
