RESUMO
PURPOSES: Necrotizing fasciitis is an aggressively progressing complication of the skin and soft tissue infections. It has dramatic course and often leads to patient's death. METHODS: In our research, we present the casuistic case concerning double suicide attempt with petroleum oil injection, complicated by the necrotizing fasciitis, patient was with deliberately withheld mental disorders. RESULTS: During the first suicide attempt, the oil substance was injected into the left cubital fossa and left toes areas, what lead to amputation of the upper left limb above the cubitial fossa and the left toes. Afterward, patient gradually recovered and survived. Two years later, another suicide attempt took place with the same substance: a 27-year-old man injected the petroleum oil into the right supraclavicular area. That affected a necrosis penetrating into the mediastinum and the patient died. CONCLUSIONS: To our knowledge, such case of the necrotizing fasciitis has not been previously reported. The mechanism of derivatives of oil influence on tissues is not investigated yet; therefore, treatment method is uncertain and sometimes ineffective.
