BACKGROUND:

Necrotizing fasciitis is an uncommon progressive infection, with high lethality that can affect any part of the body, caused mostly by a polymicrobial infection affecting the superficial fascia, subcutaneous tissue, subcutaneous fat with nerves, arteries, veins and deep fascia.

CLINICAL CASE:

A 28-year-old woman with a history of obesity and HIV, admitted to the Obstetrics Service with fever (39° C), chills and abdominal pain. A black-bluish lesion was observed, with defined edges of approximately 40 x 20 cm in the abdominal area, around the surgical wound, with blisters and great stench. Hematological study was carried out Hb: 10 g/L, C-reactive protein: 413, and Creatinine: 110 mg/dL. Culture sample of the ampoules is taken. The next day the complementary ones are repeated and Hb is observed: 8.5 g/L, C-reactive protein: 516, and Creatinine: 215 mg/dL; the result of the culture positive for Pseudomonas aeruginosa y Staphylococcus aureus. Endovenous treatment with antibiotics and surgical treatment was used. We observed satisfactory evolution of the patient without sequelae.

CONCLUSIONS:

The opportune diagnosis of this pathology allows an early action, with the consequent survival of the patients.
