Fungal infection of lung

A fungal infection of the lung, or pulmonary mycosis, is a lower respiratory tract disease caused by the inhalation and subsequent proliferation of environmental fungal spores within the pulmonary parenchyma or airways It affects both immunocompetent individuals exposed to geographically endemic dimorphic fungi—such as *Histoplasma*, *Coccidioides*, or *Blastomyces*—and immunocompromised or chronically ill patients susceptible to opportunistic pathogens, including *Aspergillus*, *Pneumocystis ji...

Pathophysiologically, the condition is characterized by alveolar and interstitial inflammation, granuloma formation, tissue necrosis, or angioinvasion leading to cavitation and pulmonary infarction
