Necrotizing fasciitis is dangerous because of its sudden onset and rapid progression. It is often associated with high morbidity and mortality if not recognized early and treated correctly. Advanced age, trauma, diabetes, immunosuppression and chronic systemic diseases (for example, hypertension, atherosclerosis and renal failure) are predisposing factors. The etiology of necrotizing fasciitis is multiple and is often polymicrobial. Early diagnosis, broad-spectrum antibiotics and prompt and adequate surgical debridement are the keys to successful treatment. Primary wound closure and sometimes skin grafting are the final definite procedures. We present two patients with necrotizing fasciitis from two different causes. Both of them survived after correct treatment.
