Objective To discuss the correlation between immune status and clinical characteristics in pulmonary cryptococcosis. Methods The clinical data of 32 non-AIDS patients with pulmonary cryptococcosis,diagnosed from August 2001 to October 2017 in Tianjin Medical University General Hospital, were retrospectively analyzed. The enrolled patients were divided into an immune-competent group with 13 cases and an immune-suppressed group with 19 cases. The clinical characteristics were compared between the two groups with different immune status.Results All 32 patients were treated for clinical symptoms. The main symptoms were cough, expectoration, fever, chest tightness, chest pain, and hemoptysis. There were no statistical differences between the two groups. The computed tomography of chest showed that there were 2 patients（6.3%） involving upper lung in the immune-competent group, and5 patients（15.6%） in the immune-suppressed group. There were 9 patients（28.1%） involving lower lung in the immunecompetent group, and 12 patients（37.5%） in the immune-suppressed group. There were 10 patients（31.3%） with nodular masses of lesions in the immune-competent group and none in the immune-suppressed group. There was 1 patient with infiltrating in the immune-competent group and 8 patients in the immune-suppressed group. There were 2 patients with mixed types of lesions in the immune-competent group and 11 patients in the immune-suppressed group. Five patients were complicated with cryptococcal meningitis, and 2 patients with eosinophilia. Conclusions The clinical characteristics of the patients with pulmonary cryptococcosis are not specific in difference immune status. The chest CT shows that the lesions of immune-competent patients are mainly nodular masses type, while lesions of immunesuppressed patients are mainly infiltrating shadow and mixed shadow. The treatment should be chose according to immune status.
