Pulmonary Blastomycosis Masquerading as Malignancy in India; Case From a Tertiary Hospital in South India

Introduction: blastomycosis is an endemic granulomatous fungal infection involving multiple organ systems predominantly the lungs. the diverse clinical spectra of the pulmonary disease encompass a subclinical infection, an acute infection mimicking a bacterial pneumonia and a chronic variant masquerading as tuberculosis or malignancy.case presentation: here we report a case of a middle-aged gentleman who was evaluated for a malignant pulmonary mass which was later identified as pulmonary blastomycosis. the diagnosis of blastomycosis was made through histopathology and was retrospectively corelated with a travel history to an endemic region. conclusion: the endemicity of this infection contributes to the diagnostic dilemma in the non-endemic setup. this warrants a high clinical suspicion in patients with a chronic pulmonary syndrome with a travel history to an endemic area.
