NECROSIS Flashcards
(32 cards)
the sum of the morphologic changes that follow cell death in a living tissue or organ.
necrosis
the major morphological manifestation of cell death.
necrosis
Necrosis may have ____ homogenous appearance as compared to normal cells
glassy
Brought by intercellular enzyme set free on the death
of the cell
COAGULATIVE NECROSIS
most seen in the heart after infarction, as well
as in the kidney and adrenal glands
COAGULATIVE NECROSIS
refers to fairly rapid total enzymatic dissolution of cells with complete destruction of the entire cell
LIQUEFACTIVE NECROSIS
can be seen in foccal bacteria and fungal infections wherein the microbes stimulates the accumulation of leukocytes and the deliberation of enzymes from the cells
LIQUEFACTIVE NECROSIS
Creamy yellow appearance because of the pus
LIQUEFACTIVE NECROSIS
could be seen in hypoxic death of the cells in CNS
LIQUEFACTIVE NECROSIS
encountered most often in the fossi of
tuberculous infection wherein there is a
conversion of a destroyed cell into granular
mass made up of a mixture of coagulated
protein and fats
CASEOUS NECROSIS
Caseous is name that such because of its
friable white appearance making it appear
as a?
cheese-like
Caseous is name that such because of its
friable white appearance making it appear
as a?
cheese-like
often structure less, have this fragmented
amorphous granular debris enclosed with
distinctive inflammatory boarder
CASEOUS NECROSIS
A foccal aggregate of immune cells that
forms in response to a persistent
inflammatory stimulus
CASEOUS NECROSIS
an area of inflammation in which the tissue has already died.
Necrotizing granuloma
A non-specific form of necrosis that refers
to a massive death of a tissue cause by a
combination of ischemia and super impose
by bacterial infection
GANGRENOUS NECROSIS
most likely because of venous occlusion
wet gangrene; moist tissue (mouth, lung, cervix, and lymph)
Dry Gangrene is often associated with?
arterial occlusion; seen in toes and feet due to arteriosclerosis
A wet gangrene cause by
a gram positive anaerobic bacteria
Gas Gangrene
a non-specific pattern of
necrosis, a vocal area of fat destruction.
Fat Necrosis
Usually occurs in a calamitous abdominal
emergency known as ______________ where there’s activated lipase that later on
causes fat necrosis.
acute pancreatitis
, fat necrosis is __________- to
the pancreas and there are remaining
steatocytes
adjacent
special from of necrosis visible by light
microscopy and usually an immune
reaction by in which complexes of antigen
and antibodies are deposited into the walls
of arteries
Fibrinoid Necrosis
The deposited immune complexes together
with fibrin that has leak-out of the vessel
produces a?
bright pink and amorphous
appearance
