A 56-year-old male from western North Carolina presented with a chronic cough, weight loss, and skin lesions, initially mimicking malignancy or other chronic infections. Diagnostic challenges arose due to non-specific symptoms and the unusual presentation. Biopsy of a skin lesion and subsequent culture identified Blastomyces dermatitidis, confirming disseminated blastomycosis. This case highlights the fungus's ability to mimic various conditions, earning it the moniker "great pretender." Early consideration of endemic fungal infections in patients with atypical presentations and relevant exposure history, especially in endemic areas, is crucial for timely diagnosis and treatment.
Key note: Disseminated blastomycosis can mimic malignancy, requiring a high index of suspicion for accurate diagnosis.
