Hamartoma is …….
not a malignant tumor, grows at the same rate as the surrounding tissues.
* composed of tissue elements normally found at that site, but which are growing in a disorganized mass
Herpangina (p. 150)
vesicular lesions typically in the pharynx

Hemochromatosis (p. 163)
- autosomal recessive
- Deposition of iron in the liver (cirrhosis), pancreas (DM), heart, adrenal, thyroid, parathyroid, skin, and anterior pituitary, resulting in organ dysfunction
- Note that Hemosidrosis is iron overload for any cause
Wilson’s Disease (p. 163)
- Autosomal recessive
- Also called hepatolenticular degeneration
- copper accumulates in tissue
- There is abnormality of hepatic excretion of copper
- There is deposition of green pigment
in periphera of cornea.
Hepatorenal disease (p. 163)
decreased renal function due to liver cirrhosis (in particular alcoholic hepatitis) or fulminant hepatic failure
