Pulmonary blastomycosis presenting as primary lung cancer.

Abstract

BACKGROUND:Blastomycosis is an endemic mycosis in North America that is caused by the dimorphic fungus Blastomyces dermatitidis. The illness is a systemic disease with a wide variety of pulmonary and extra-pulmonary manifestations. The initial presentation of blastomycosis may easily be mistaken for other infectious or non-infectious etiologies. CASE PRESENTATION:We present the case of a 52-year-old African-American male and former smoker that presented to his primary care provider with a 2-week history of non-productive cough, night sweats and weight loss. Initially diagnosed with primary lung malignancy, the patient was subsequently found to have pulmonary blastomycosis mimicking lung cancer. The patient underwent a successful course of treatment with posaconazole. CONCLUSIONS:Chronic blastomycosis can present with clinical and radiographic features indistinguishable from thoracic malignancies. There is no clinical syndrome specific for blastomycosis, thus a high degree of suspicion is required for early diagnosis. In this case report, we review recent evidence in radiographic features, diagnostic considerations and treatment of the disease.

Broadly, my research focuses on a range of clinical and social issues that affect persons living with or at risk for HIV infection in resource-poor settings. In Tanzania, our group is applying novel methods to optimize HIV testing uptake among high-risk groups. We recently demonstrated that the Discrete Choice Experiment (DCE), a form of stated preference survey research, is a robust tool for identifying (a) which characteristics of HIV testing options are most preferred by different populations and (b) which tradeoffs individuals make in evaluating testing options. Building on more than a decade of productive HIV testing research in the Kilimanjaro Region, the next phase of our NIMH funded project will test the hypothesis that DCE-derived HIV testing options significantly increases rates of testing among groups at high risk for HIV infection. This work holds promise not only for optimizing HIV testing uptake in the Kilimanjaro Region, but also for applying novel tools in the service of translational epidemiology and implementation research.
