 Disseminated Blastomycosis in a Dog   (Site not responding. Last check: 2007-10-21)
Histopathologic Findings:  The primary lesion in the lungs was a multifocal to confluent pyogranulomatous pneumonia.  Numerous intralesional, 10-20μm in diameter, spherical yeasts with a thick, double refractile cell wall, basophilic granular central zone, and occasional broad-based budding consistent with Blastomyces dermatitidis were present.   Bronchial lymph node lesions included pyogranulomatous lymphadenitis with intralesional Blastomyces dermatitidis.
Most cases of blastomycosis are acquired by inhalation of aerosolized conidia into the lungs.  After inhalation, the conidia are phagocytized by alveolar macrophages and transform the mycelial phase to the yeast phase.  The yeast stimulates local cell-mediated immunity which results in a marked suppurative or pyogranulomatous inflammation.  The incubation period varies from 5-12 weeks.
