Clinical Information
- A fungal infection caused by inhalation of spores of blastomyces dermatitidis. It presents with flu-like symptoms including fever, chills, cough, pleuritic chest pain and myalgias. It may lead to a chronic granulomatous pulmonary infection and disseminate to other anatomic sites including skin, nervous system and bones.
- 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.
