[Pulmonary mass: Thinking beyond malignant causes - A case of histoplasmosis].

Abstract

A 49-year-old patient was presented for clarification of a pulmonary nodule and lymphadenopathy. He had undergone surgery for removal of a squamous cell carcinoma from the lip and a renal cell carcinoma. Follow-up examinations showed new changes in the lungs and lymph nodes. An initial suspicion of malignant metastases was not confirmed; instead, fungal organisms were detected. Through a detailed medical history, positive serology, and a specific PCR, the diagnosis of pulmonary histoplasmosis was finally made.
