Pulmonary Mucormycosis is a rare postoperative infection complication charactered with rapid deterioration and high mortality. In this case, a 33-year-old patient underwent kidney transplantation with regular immunosuppressive therapy. On 38 days posttransplant pulmonary patchy shadows can be seen in the radiological examination and rounded into large cavity formation with splenic rupture 25 days later. The diagnosis of mucormycosis was confirmed by lung biopsy and spleen histopathology. This case is a reminder that early diagnosis is imperative, meanwhile, rational antifungal therapy, timely elimination of immunosuppressants and alternative abandoning the graft should be prudently assessed in the treatment of mucormycosis.
