ObjectiveTo describe the clinical manifestations and diagnosis of pulmonary mucormycosis.MethodsWe presented 5 proven diagnosed cases of pulmonary mucormycosis in our hospital and reviewed all proven cases of pulmonary mucormycosis previously reported in mainland China. Publications in the form of case reports and articles between January 1982 and December 2011 were searched from Wan Fang Data and China Hospital Knowledge Database.ResultsOf the 5 patients in our hospital, the main symptoms included cough, fever, and hemoptysis. Two cases were diagnosed by transbronchial lung biopsy (TBLB), 1 by surgery, 1 by CT-guided percutaneous lung biopsy, and 1 by blood culture. Three patients were cured by antifungal chemotherapy alone, 1 was cured by surgery, and 1 died. Forty-six proven diagnosed cases of pulmonary mucormycosis were retrieved from Wan Fang Data and China Hospital Knowledge Database using key word (pulmonary mucormycosis). Of the 51 patients in total, there were 31 males and 20 females, with a mean age of (47 ± 13)years. The most common risk factors for pulmonary mucormycosis were poorly controlled diabetes mellitus (18 cases), administration of immunosuppressants (7 cases), malignancy (5 cases) and kidney diseases (5 cases). Chest CT showed nodules (27 cases), infiltrates (21 cases), and cavities (18 cases). White blood cell count and neutrophil percentage were elevated in 26 patients. Eighteen cases were diagnosed by histological study of transbronchial biopsy or TBLB specimen. The diagnosis was proven with surgical specimen in 15 patients, CT-guided percutaneous lung biopsy specimen in 7 patients, autopsy in 4 patients, skin biopsy in 1 patient, and renal biopsy in one patient. Three cases were diagnosed by pleural effusion cultures and 2 were diagnosed by blood cultures. Administration of low-dose liposomal amphotericin B (AMB) alone or combined with posaconazole in 12 patients were effective and safe. Fourteen patients who had received surgical resection were cured.ConclusionsThere were no specific clinical features of pulmonary mucormycosis. Transbronchial biopsy and CT-guided percutaneous lung biopsy are useful diagnostic tools for pulmonary mucormycosis. Surgical resection and administration of low-dose liposomal AMB alone or combined with posaconazole were all effective and safe.
