Endocrine Flashcards
Conn Disease
Primary aldosterone elevation
Monckeberg Medial Sclerosis
- is degenerative calcification of the media of large-to-medium-size muscular arteries
- usually in the extremities of older persons, or in advanced chronic kidney disease
- osseous metaplasia may be seen, but usually no clinical impairment
Fibromuscular dysplasia
• is a rare, noninflammatory thickening of large-to-medium-size arteries (NO INFLAMM OR NECROSIS)
- -women of reproductive age mostly
- -can lead to renal artery stenosis
Fusiform anurysm
along axis of vessel. usually abdominal are fusiform.
Types of DVT
- deep venous thrombosis refers to both phlebothrombosis and thrombophlebitis
- thrombophlebitis - inflammation and secondary thrombosis of smaller veins, often as a reaction to bacterial infection
- phlebothrombosis - venous thrombosis not caused by infection or inflammation
- usually associated with prolonged best rest or reduced cardiac output
- anticoagulant (ex. protein C, antithrombin) deficiencies also increase risk
- major problem is pulmonary embolism
Hemangiomas
common, benign vascular channel tumors. Look like birthmarks (capillary hemangiomas are birthmarks). Cherry red spots.
Juvenile / Strawberry Hemangioma
- congenital lesions that grow rapidly in newborns and then regress by 3-5 years
- have packed masses of capillaries that are usually filled with blood and separated by connective tissue stroma
Hemangioendothelioma
is a vascular tumor of endothelial cells
• intermediate between benign hemangiomas and malignant angiosarcomas
Angiosarcoma
a rare, highly malignant tumor of endothelial cells
• small, painless, demarcated red nodules —> larger, fleshy, unencapsulated, pale gray masses —> central necrosis, softening, and hemorrhage
–stains for CD31
Cystic lymphangioma
benign, soft, large, spongy, pink lesion in the neck and axilla
Marantic endocarditis
Non-bacterial endocarditis
• associated with cancer, DIC, or nonneoplastic wasting diseases
Rheumatic heart disease
Group A strep (pyrogenes)
Mitral valve tropism – fusing of leaflets (commissural fusing)
Carcinoid syndrome
uniquely affects right-sided valves
• arises in patients with carcinoid tumors, usually of the small intestine, that have metastasized to the liver
• hypothesized cause: too much serotonin and other vasoactive amine and peptides, which travel through the R. heart before they can be metabolized in the lung
• non-inflammatory plaques of dense, fibrous gray tissue —> leaflet deformation and shrinkage —> tricuspid regurgitation or stenosis, pulmonary stenosis
Myxoma
is the most common primary cardiac tumor
• glistening, gelatinous, polypoid masses mostly in the L. atrium
• causes mitral valve dysfunction, embolization to the brain
AV Canal
ASD and VSD often in Down’s syndrome
