Pulmonary — Flashcards

Flashcard 11: The final phase of lobar pneumonia is _____ with regeneration of tissue via type II pneumocytes

Answer: resolution

Flashcard 12: Permanent airway remodeling due to recurrent bronchial inflammation (with eosinophils) is suggestive of chronic _____

Answer: asthma

Extra: * e.g. structural changes to bronchial wall

Flashcard 13: _____ lesions are small, vascular channels that may be seen with severe, long standing pulmonary hypertension

Answer: Plexiform

Flashcard 14: _____ is a pneumoconiosis that presents with noncaseating granulomas in the lung, hilar lymph nodes, and systemic organs

Answer: Berylliosis

Extra: Noncaseating granuloma Photomicrograph of lymph node tissue (H&E stain; high magnification) A high density of immune cells (example of a macrophage indicated by red arrowhead) is visible at the periphery of the image. These cells surround a formation (black dashed outline) of extracellular matrix (black arrowhead) in which single multinucleated giant cells (green overlay) are visible. These findings are typical of noncaseating granuloma.

Flashcard 19: Asbestosis lesions may contain _____ bodies, which are golden-brown fusiform rods resembling dumbbells

Answer: Asbestos (ferruginous)

Extra: *Screw with nuts in bottom right corner: in the macrophages, asbestos fibers are coated with an iron containing proteinaceous material -> ferruginous bodies (brown "beaded appearance" on H&E)
