Necrotizing Fasciitis in a 9-year-old Girl.

This report describes a rare case of necrotizing fasciitis (NF) in a previously healthy 9-year-old girl, emphasizing the complexities and urgent needs associated with its diagnosis and treatment in children. NF, a severe soft-tissue infection characterized by rapid progression and often fatal outcomes, presents diagnostic challenges owing to nonspecific initial symptoms such as pain, erythema, and edema. This patient presented to the emergency department with fever, arm redness, and blisters after the initial discharge with antibiotics from another facility. Despite the lack of clear historical indicators for the cause, the clinical and laboratory findings, including a high Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score of 9, led to immediate surgical intervention. Treatment included multiple sessions of surgical debridement and broad-spectrum antibiotics, culminating in successful skin grafting. This case underscores the importance of high clinical suspicion and prompt surgical consultation to manage potential NF, mainly when the initial symptoms may be misleading. This report highlights the critical need for early recognition and aggressive treatment to improve the prognosis of pediatric cases of NF.
