Lung adenocarcinoma with coexisting pulmonary cryptococcoma.

ABSTRACT

A 73-year-old female was referred to our hospital in June 2000 for the evaluation of an abnormal shadow in the left upper lobe of her lung and two other shadows in the left lower lobe. A computed tomography examination revealed an ill-defined tumor with ground glass opacity in the left upper division segment, suggesting a primary lung adenocarcinoma, and two well-defined nodules in the left lower lobe, suggesting metastatic carcinomas. A transbronchial lung biopsy of the tumor in the upper division segment confirmed the presence of an adenocarcinoma but failed to provide a histological diagnosis for the nodules in the lower lobe. A partial resection of the left lower lobe using video-assisted thoracoscopy revealed granulomatous tissue with no signs of malignancy. A curative resection of the adenocarcinoma in the left upper division segment was therefore performed. Histologically, the resected specimens obtained from the left lower lobe were diagnosed as cryptococcomas. The patient was diagnosed as having a stage IA lung adenocarcinoma and two cryptococcomas. The patient is presently well and has not experienced any recurrences or relapse for 3 years since the resection.
