Blastomycosis

A fungal infection that may appear in two forms: 1) a primary lesion characterized by the formation of a small cutaneous nodule and small nodules along the lymphatics that may heal within several months; and 2) chronic granulomatous lesions characterized by thick crusts, warty growths, and unusual vascularity and infection in the middle or upper lobes of the lung.

A disease caused by a fungus.

An infection caused by Blastomyces.

Infection, caused by the fungus of Blastomyces dermatitidis, that produces lesions on the skin, especially in exposed areas, or the lungs and other internal organs. Treatment is by antifungal agents.

A chronic infection caused by a fungus inhaled into the lungs and transported by the bloodstream to other organs, principally the skin and bones. The fungus that causes blastomycosis is found in the soil, primarily in the southeastern United States and the Mississippi Valley. The infection is common in dogs, but it is not known to be transmitted from animals to humans. It occurs mostly in middle-aged men.

Any disease caused by parasitic fungi of the genus Blastomyces, which may affect the skin (forming wart like ulcers and tumors on the face, neck, hands, arms, feet, and legs) or involve various internal tissues, such as the lungs, bones, liver, spleen, and lymphatics. There are two principal forms of the disease: North American blastomycosis. ( Gilchrist ‘s disease), caused by B. dermatitidis; and South American blastomycosis, caused by B. brasiliensis. Both diseases are treated with antibiotics (such as amphotericin).
