AbstractTo describe the characteristics of concomitant lung cancer and pulmonary cryptococcosis (PC) cases.A total of 8 patients with lung cancer and coexisting PC, who were admitted to Fuzhou Pulmonary Hospital of Fujian from 1st January 2009 to 31st December 2015 and whose diagnoses were confirmed by pathological examinations, were studied.One patient had a history of diabetes mellitus and 1 had a history of treated with surgery. The lesions in 7 cases manifested as nodular shadows; only 1 case showed the lesion of the 2 diseases mergedmixed together, and it manifested as a large flake-like infiltrated shadow in the same lobe. The histological type in all of the patients was lung adenocarcinoma. Lung cancer stage was advanced (III-IV) in 25.0% of the cases. The 5 patients who received surgery and drug treatment are presently healthy following resection. Recurrence and metastasis of lung cancer following surgery occurred in 2 patients in whom the tumor was controlled again after anti-tumor treatment. One patient with advanced lung cancer and PC was treated with antifungal therapy in combination with antineoplastic chemotherapy, but she failed to improve and died 10 months after symptom onset during the follow-up period.PC coexisting with pulmonary carcinoma is rare. PC can manifest as pulmonary nodules and mimic malignant lesions, so it must be considered during a differential diagnosis of pulmonary nodules, especially in immunosuppressed patients.
