Chronic pulmonary histoplasmosis

Chronic pulmonary histoplasmosis is a persistent, progressive fungal infection of the respiratory system caused by the inhalation of *Histoplasma capsulatum* spores

Chronic pulmonary histoplasmosis is a persistent, progressive fungal infection of the respiratory system caused by the inhalation of *Histoplasma capsulatum* spores Clinically, affected patients experience an insidious, prolonged illness characterized by chronic productive cough, hemoptysis, dyspnea, low-grade fevers, night sweats, fatigue, and substantial weight loss, which can lead to progressive loss of lung volume and respiratory failure if left unmanaged

This clinical entity predominantly affects older adults and individuals with pre-existing structural lung diseases, particularly emphysema or chronic obstructive pulmonary disease Pathophysiologically, the organism colonizes abnormal lung spaces, prompting sustained necrotizing inflammation, pulmonary fibrosis, and progressive apical or upper-lobe cavitation that closely mimics pulmonary tuberculosis Clinically, affected patients experience an insidious, prolonged illness characterized by chroni...
