Pulmonary cryptococcosis coexisting with adenocarcinoma
Pulmonary cryptococcosis is a common fungal infection frequently seen in immunocompromised patients. Owing to its nonspecific clinical and radiographic features, the differential diagnosis with secondary tuberculosis, malignant tumor, and bacterial pneumonia is sometimes difficult.

Published in the Journal of Medical Case Reports, the authors present a case of a 52-year-old immunocompetent woman who presented to the emergency department complaining of headache and vomiting accompanied by postural changes. She was diagnosed with pulmonary cryptococcosis according to results of laboratory tests, computed tomography, and percutaneous lung biopsy.

Owing to the poor therapeutic effects of 6-month fluconazole treatment, she underwent a second percutaneous lung biopsy and was diagnosed with pulmonary cryptococcosis coexisting with adenocarcinoma. Delayed treatment of malignant tumor resulted in lymph node metastasis, higher pathologic stage, and probably poorer prognosis.

Learning Point:-
This patient’s case serves as a reminder not to misdiagnose pulmonary cryptococcosis coexisting with adenocarcinoma.
