Pulmonary V: Pathology Flashcards
What pathology? Abnormal cells with large nuclei that form gland-like structures
Adenocarcinoma
What pathology? Air spaces filled with pink fluid and macrophages
Pulmonary Alveolar Proteinosis
What pathology? Airway centered chronic inflammation with lymphocytes and histiocytes, non-necrotizing granulomas, and focal organizing pneumonia
Hypersensitivity Pneumonia
What pathology? Benign Nodular process involving inflammation with eosinophils and a stellate scar around the airway
Pulmonary Langerhans Cell Histiocytosis
What pathology? Blood and iron containing macrophages in the air space, mild thickening of alveolar septa, may be associated with capillaritis
Diffuse Alveolar Hemorrhage
What pathology? Brown pigmented airspace macrophages found diffusely in the airways
Desquamative Interstitial Pneumonia
What pathology? Brown pigmented airspace macrophages in small bronchioles and adjacent air spaces
Respiratory Bronchitis
What pathology? Chronic inflammation, squamous metaplasia, mucus gland hyperplasia
Chronic bronchitis
What pathology? Dilation of airway compared to surrounding vasculature
Bronchiectasis
What pathology? Easily crushed cells, blue cells with scan cytoplasm, abundant necrosis
Small Cell Carcinoma
What pathology? Emphysema worse in the lower lobes and not worse around airways; associated with _______.
Panlobular emphysema; alpha-1-antitrypsin deficiency
What pathology? Emphysema worse in the upper lobes and around bronchioles; associated with ______.
Centrilobular emphysema; smoking
What pathology? Enlarged air spaces, broken alveolar septa, subpleural blebs
Emphysema
What pathology? Foreign material in the airspace with multinucleated gian cells
Aspiration pneumonia
What pathology? Heterogeneous fibrosis with honeycombing and fibroblastic foci
Usual Interstitial Pneumonia
What pathology? Hyaline membranes in the air space, inflammation and fibroblastic tissue in the alveolar walls
ARDS/Diffuse Alveolar Damage
What pathology? Inflammation and fibrosis between the smooth muscle and mucosa squeeze the airway lumen closed
Constrictive/Obliterative Bronchiolitis
What pathology? Inflammation in the walls of small airways that do not contain cartilage
Chronic cellular Bronchitis
What pathology? Inflammatory cells in alveolar spaces due to infectious causes
Acute pneumonia
What pathology? Large bizarre appearing cells that lack the characteristics of other malignancies
Large Cell Carcinoma
What pathology? Lymphoid aggregates with germinal centers in bronchiolar walls
Follicular Bronchiolitis
What pathology? Muscular hypertrophy of pulmonary arteries, muscularization of artierioles, plexiform lesions
Pulmonary Hypertension
What pathology? Necrotizing or non-necrotizing clusters of histiocytes and multinucleated giant cells seen at the level of the bronchioles
Granulomatous Bronchiolitis
What pathology? Nests and ribbons of neuroendocrine cells with powdery salt-and-pepper chromatin
Carcinoid
What pathology? Organizing fibrin clots in pulmonary arteries
Thromboembolic Disease
What pathology? Plugs of loose myxoid fibroblastic tissue in airspaces, usually patchy, may have densely consolidated areas with fibrin
Organizing pneumonia
What pathology? Polarizable crystals around vessels, associated with IV drug use
Talc embolism
What pathology? Polygonal cells with hyperchromatic nuclei and abundant cytoplasm, keratin pearls
Squamous Cell Carcinoma
What pathology? Thickened sub-basal lamina, eosinophilic inflammation, mucus hypersecretion, smooth muscle hyperplasia
Asthma
What pathology? Uniform inflammation or fibrosis with minimal honeycombing or fibroblastic foci
Non-Specific Interstitial Pneumonia
