Necrotizing fasciitis of the left upper limb in a male patient: Case report

Necrotizing fasciitis (NF) is a rapidly progressive, life-threatening soft-tissue infection that primarily involves the superficial fascia and subcutaneous tissue. Early diagnosis, prompt surgical debridement combined with broad-spectrum antimicrobial therapy and intensive supportive care are essential to reduce mortality and the need for major amputations. Although upper-limb NF is less frequent than lower-limb involvement, when it affects the upper extremity it has been associated with higher mortality and greater perioperative morbidity. Most cases arise after trauma or postoperative infection, but NF may rarely develop in the setting of pressure injuries. The disease usually follows an aggressive course and can be fatal, particularly in outpatients with immunosuppression or chronic comorbidities.

We report the case of a 58-year-old male from a rural area with a history of type 2 diabetes mellitus and recent trauma to the left upper limb after a motorcycle accident. The patient initially resorted to traditional therapies, including treatment by a bonesetter and application of topical oils, delaying hospital care.
