    Abstract:
    OBJECTIVE: To clarify the clinical feature, diagnosis and therapy of the pulmonary cryptococcosis (PC). METHODS: A retrospective study of cases with PC who were diagnosed by pathological examinations between January 1996 and December 2010 was conducted. Eighty-one cases were enrolled in the study (58 male and 23 female patients; mean age of (51±11) years). Forty-one cases were asymptomatic at the time of diagnosis. There were single pulmonary lesions in 50 cases, and multiple lesions in 31 cases. Fourteen lesions (17.3%) were located in left upper lobe, 27 (33.3%) in left lower lobe, 21 (25.9%) in right upper lobe, 3 (3.7%) in right middle lobe, 28 (34.6%) in right lower lobe, and 3 (3.7%) diffusely involved bilateral lungs. The tumors ranged from 0.8 to 10.0 cm in diameter with a mean of (2.9±1.8) cm. All the cases were misdiagnosis prior to the surgical resection, and histologically confirmed by postoperative pathological specimens. RESULTS: All the cases received surgical treatment including complete resection in 69 cases, and palliative resection in 12 cases. Resections were performed by means of video-assisted thoracoscopy in 31 cases and thoracotomy in 50 cases. Surgical resections included pulmonary wedge excisions in 42 cases, and lobectomies in 39 cases. After histological confirmation, 63 cases (77.8%) were treated with antifungal agents, which consisted of fluconazole in 38 cases, itraconazole in 18 cases, amphotericin B in 6 cases, and flucytosine in 4 cases. There were no intraoperative death, but two cases died for cryptococcal meningoencephalitis in the postoperative period. Operative morbidity occurred in 7 (8.6%) cases. The median follow-up was 42.5 months (6 to 84 months). There were 2 local relapses of PC, and 9 cases with complications of anti-fungal agents. CONCLUSIONS: The clinical manifestations of PC are mild and non-specific, with no characteristic radiographic manifestations. Surgical resection is usually indicated for definite diagnosis and treatment. Antifungal drug therapy is indispensable even after complete resection.
