blastomycosis blas·to·my·co·sis (blās'tō-mī-kō'sĭs)
A chronic granulomatous and suppurative disease caused by the dimorphic fungus Blastomyces dermatitidis, originating as a respiratory infection, and usually spreading to the lungs, bones, and skin.
infection of the skin and viscera caused by fungal organisms of the genus Blastomyces. There are two major types of blastomycosis: the North American, caused by B. dermatitidis, and the South American, caused by B. brasiliensis. In North American blastomycosis, skin and lung lesions are most common: pulmonary lesions vary in size from granulomatous nodules to confluent, diffuse areas of pus-forming inflammation involving the entire lobe of the lung. In the skin, micro-abscesses lie just beneath the epidermis, the outermost layer of the skin, and are associated with a granulomatous appearance of the surrounding skin
