Mucormycosis are opportunist infections occurring usually among predisposed patients. We report a case of an 18-year-old male with a severe thoracic trauma who developed an Absidia infection on his contused pulmonary parenchyma, without presenting the usual risk factors (diabetes mellitus, immunodeficiency). The early diagnosis using bronchoscopy has probably improved the outcome by allowing a faster treatment. After 18-months, the infectious process resolved thanks to a combination of a medical treatment composed of high-dose amphotericin B lipid formulation, itraconazole and a complementary surgical treatment.
