Disseminated Blastomycosis
Imaging findings
Chest radiograph and CT demonstrate diffuse miliary nodules in a random distribution and a larger, dominant pulmonary nodule. Cutaneous photos show multiple ulcerative, crusted, and vesicular skin lesions. Biopsy of the skin lesions confirmed the presence of Blastomyces yeast.
Key takeaways
Blastomycosis is a fungal infection endemic to the Ohio and Mississippi River valleys, the Great Lakes, and the St. Lawrence River. Inhalation of spores leads to pulmonary infection, which can disseminate hematogenously, most commonly to the skin, bones, and genitourinary tract. Cutaneous lesions typically present as crusted, verrucous, or ulcerative plaques, and finding the broad-based budding yeast on biopsy is diagnostic.
