test 1 - pathology of tuberculosis and fungal diseases Flashcards
waxy wall Ag, patient develops antimicrobial, cell mediated immunity resulting in hypersensitivity to tuberculosis Ag
tuberculosis
ghon lesion - single or multiple subpleural focus
primary pulmonary tuberculosis
initially little fibrosis, later there is caseative necrosis and clacifications
tuberculosis
lunges studded with miliary tubercles (mostly monocytes(
primary disseminated tuberculosis
subsequent exposure or reactivation of healed lung lesion
post primary tuberculosis
opportunistic infection of immunocompromised patients (AIDS)
25% fatal
lungs massively consolidated
pneumocystic carinii
caused by inhalation of aspergillus fumigatus
2nd most common immunocompromised infection for patients
aspergillosis of the lung
caused by histoplasma capsulatum via respiratory route
endemic in mississippi and ohio river valleys
histoplasmosis
caused by inhalation of coccidiodes immitis
fever, cough, residual pulmonary nodule
coccidomycosis
caused by inhalation of blastomyces
found in central necrosis and caseation
blastomycosis
