Introduction:

Necrotizing fasciitis is a rare, rapidly progressive infection of subcutaneous tissue and fascia, characterized by widespread fascial necrosis.

Clinical case:

A 62-year-old female, with diabetes mellitus. Two week prior to consultation she presents with a progressive perimeter augmentation of the left thigh and fever. In the physical examination of the lower extremities: left thigh and knee with augmentation of the perimeter, erythema, hyperthermia, pain and subcutaneous emphysema. In the “X” rays and CT shows gas in the subcutaneous tissue in the knee, thigh and around the hip joint. We drain the accumulated pus, and debride devitalized tissue and placed a negative pressure therapy. Later we performed two more exchanges of the system. We closed the anterior and lateral wound. Three days after the last surgery, we dismissed the patient and was referred to physical rehabilitation.

Conclusion:

Negative pressure therapy provides rapid wound healing for a tertiary closing or skin graft. Prompt rehabilitation and early ambulation helps patients return to their daily activities.
