Objective To improve the knowledge of pulmonary mucormycosis through summarizing the clinical features and treatment of the disease. Methods A retrospective analysis was conducted on two cases of mucormycosis. The literature review was carried out with " pulmonary mucormycosis” as the research terms respectively in CNKI and Pubmed database. Search time ranged from January 2000 to June 2016. Results The first case was a 61-year-old male patient complained of cough, expectoration and dyspnea for 5 days. Chest computerized tomography (CT) showed lung nodules in the right upper lobe and bronchial cut off sign of apical bronchus. The patient received bronchoscopic examination and pathological findings indicated mucormycosis. Amphotericin B was recommended for the treatment. The patient recovered after treatment and was discharged. The second case was a 44-year-old female patient admitted to our hospital due to cough accompanied with expectoration and fever for over 10 days. Chest CT scan showed multiple double-pulmonary circular nodules and cavities with different sizes and clear boundary. The maximum cavity diameter was about 1.8cm, and the density of soft tissue was found in the part of the cavity. The patient received CT-guided percutaneous lung biopsy and pathological findings indicated fungal hyphae which was accorded with mucor infection. The patient received amphotericin B, voriconazole and posaconazole treatment, but with bad curative effect. She gave up therapy and died one week later after discharged. A total of 6 literatures were reviewed in above-mentioned databases. The clinical manifestations were nonspecific and the patients were likely to accompany with other diseases. The duration from the onset of symptoms to exact diagnosis was 37.5 days. Chest CT scan and pathological examination played important roles in the diagnosis of mucormycosis. Proper antifungal treatment could improve the prognosis. Conclusions Mucormycosis is a rare invasive fungal disease with high mortality. The clinical manifestations are nonspecific. Early diagnosis and appropriate treatment contribute to better prognosis.
