Renal abscess involving mucormycosis by immunohistochemical detection in a patient with acute lymphocytic leukemia: a case report and literature review.

A 14-year-old girl with acute lymphocytic leukemia complained of right flank pain and fever. As her fever was prolonged, she underwent renal biopsy and was diagnosed with mucormycosis. We performed right nephrectomy, and subsequent pathological examination of her tissue specimen also detected mucormycosis. Here, we report a rare case of renal mucormycotic abscess.
