Caseous necrosis is a distinctive form of coagulative necrosis, is encountered most often in foci of tuberculous infection.
The term caseous is derived from the cheesy white gross appearance of the area of necrosis.
On microscopic examination, the necrotic focus appears as amorphous granular debris seemingly composed of fragmented, coagulated cells and amorphous granular debris enclosed within a distinctive inflammatory border known as a granulomatous reaction. Unlike coagulative (...)

polyps
17 November 2004polyp. Adj. polypous, polypoid WKP
Definition: A polyp is an abnormal growth of tissue projecting from a mucous membrane.
If it is attached to the surface by a narrow elongated stalk, it is said to be pedunculated. If no stalk is present, it is said to be sessile.
Polyps are commonly found in the colon, stomach, nose, ear, sinus(es), urinary bladder, and uterus.
They may also occur elsewhere in the body where mucous membranes exist like the cervix, vocal folds, and small intestine. (...)
