"Polyarteritis affects small to
medium-sized arteries.
-
Associated with hepatitis B, and
circulating immune complexes are thought
to play a role, although, like many
immunologic diseases, this remains
speculative.
-
Clinically, any artery can be
affected, and thrombosis may occur.
-
Symptoms are related to the organ
involved, although patients also have
constitutional symptoms, like malaise,
fever, and weight loss.
-
Histologically, fibrinoid
necrosis is prominent, with a variable
perivascular infiltrate of lymphocytes
and polymorphs. "
