[Systemic mucormycosis in dialysis: computed tomography picture and histologic lesions].

Mucormycosis (zygomycosis) is an uncommon mycosis which can be contracted from the environment and which is responsible for rhino-orbital, pulmonary, gastrointestinal, cerebral or disseminated infections. Severe immunodepression, such as that caused by leukemia, lymphomata and organ graft, or treatment by desferrioxamine, may predispose to pulmonary and systemic forms. In the present work the authors describe a case of systemic mucormycosis, with unfavourable outcome, which arose in a pediatric peritoneal dialysis patient, then transferred to hemodialysis, without evident predisposing factors. In particular they refer to the CAT reports and to lymphonodal and peritoneal histological lesions which allowed them to attain the diagnosis.
