7 Flashcards
Dense lymphocytic infiltrate of portal triad and granunlomatous destruction of intralobular bile ducts- florid duct lesions
Micronodular regeneration of periportal tissues
Pbc
Lobular mononuclear inflammation, hepatocyte balloon degeneration, ground glass hepatocytes. Granular eosinophilic
Cytotoxic t cell mediated hepatocyte undergo apoptosis
Finely granular, diffusely homogeneous pale eosinophilic cytoplasm(ground glass appearance)
Hepatitis B
Portal and periportal lymphoplasmacytic infiltration of liver i-e interface hepatitis
AIH
Fibrous obliteration of bile ducts , concentric periductal deposition of connective tissue in an onion skin pattern. Beading of intra and extra-hepatic bile ducts on ERCp.
Strongly ass with UC
Cholestatic pattern of liver injury
Primary sclerosing cholangitis
Noncaseating granuloma with hepatic fibrosis and multinucleated giant cells formation
Sarcoidosis
Nodular lymphoid hyperplasia of intestine
CVID
Intranuclear/intracytoplasmic inclusion bodies
CMV ESOPHAGITIS
Eosinophilic intranucléar inclusions (cowdry type A) in multinuclear squamous giant cells at ulcer margins-latent virus cause reinfection/symptoms- punched out ulcers volcano like appearance
HSV ESOPHAGITIS
Insular (nesting) masses of small round cells with peripheral palisading , granular cytoplasm, small nucleus and salt and pepper chromatin.
Electron microscopy: dense core granule contain bradykinin, serotonin and histamine and hormones (gastrin)
Carcinoid syndrome
Connective tissue,smooth muscle and disorganised mucosal cells-polyp?
Hemartamous polyps
Small,non mucosal cells that form glands and crypts-poly?
Hyperplastic polyps
Stacked circular oesophageal rings, linear furrows, small scattered whitish papules called eosinophilic microabcesses. Food impaction
Eosinophilic esophagitis
Fibrous replacement of muscularis in lower oesophagus, esophageal smooth muscle atrophy- decrease LES and dysmotility and peristalsis
Crest/ systemic sclerosis
Enlarged but nontender gallbladder-
Courvosier sign-pancreatic adénocarcinoma
Large eosinophilic hyperchromatic squamous cell with scant cytoplasm arranged in islands . Nuclear atypia and prominent keratization or keratin pearls.
