To the Editor:Invasive pulmonary mucormycosis(IPM)is a rare but life-threatening opportunistic fungal disease with a high mortality rate of 40%to 80%.[1]Although IPM accounts for approximately 9.2%of all mucormycosis cases,it has the highest mortality rate(66.6%).A definitive diagnosis of IPM depends on the histopathological findings,regardless of culture results of the respiratory tract specimens or lung tissues.
