[Disseminated fusariosis during autologous stem cells transplant].

Fusarium is a filamentous brown fungus found in soil, on plants and outdoors responsible for localized or disseminated infections. Diagnosis is based on blood cultures and skin biopsy. Disseminated fusariosis is a rare and serious fungal infection, that occurs especially in neutropenic immunosuppressed patients. Treatment is difficult and mortality is estimated between 50 and 70% in adult patients. This infection is rare in Morocco. We report a case of systemic fusariosis in patient with multiple myeloma during a second autologous stem cell transplant. At day 4 of the autologous stem cells transplant the patient had febrile neutropenia and diarrhea; he received ceftazidime, metronidazole and amikacin for 2 days. The patient still febrile was treated by imipenem and vancomycin without bacteriological proof. At day 10 the patient presented difficulty of breathing and wheezing on auscultation of the lungs, and received nebulization with salbutamol every 6 hours. The CT scan shows interstitial infiltrate of the right lung with micronodules. At day 11 he was treated by voriconazole with clinical improvement. At day 19, Fusarium sp. was identified on the Sabouraud blood culture. The patient left the transplant unit at day 25, he received 6 weeks of voriconazole with clinical and radiological improvement.
