granuloma, calcified
A granuloma that contains
calcium deposits. Because it usually takes time for
calcium to be deposited in a granuloma, a calcified
granuloma is generally assumed to be an old gran-
uloma.
granuloma, fishbowl
Localized nodular skin
inflammation (small, reddish, raised areas of skin)
that is caused by the bacterium Mycobacterium
marinum (M. marinum). Fishbowl granuloma is
typically acquired by occupational or recreational
exposure to salt or fresh water; often it is the result
of scratches or scrapes of the skin during the care
of aquariums. The diagnosis is confirmed through a
culture of tissue specimens that yield M. marinum.
The infection can be treated with a variety of antibi-
otics. Also known as swimming pool granuloma.

granuloma annulare
A benign, chronic skin
condition characterized by raised, reddish bumps
arranged in a circular or ring pattern. Usually, there
are no other symptoms. Granuloma annulare is
most common in children, predominantly girls. Its
cause is unknown. Granuloma annulare typically
disappears on its own within several years.
Treatment is generally unnecessary except for cos-
metic reasons.

granulomatosis, Wegener
An inflammatory
disease of small arteries and veins (vasculitis) that
can involve any organ but classically involves vessels
supplying the tissues of the lungs, nasal passages
(sinuses), and kidneys. Symptoms include fatigue,
weight loss, fever, shortness of breath, bloody spu-
tum, joint pains, and sinus inflammation, some-
times with nasal ulcerations and bloody nasal
discharge. Wegener granulomatosis most com-
monly affects young or middle-aged adults. The
diagnosis of Wegener granulomatosis is confirmed
by finding evidence of vasculitis and granulomas on
biopsy of tissue that is inflamed. Treatment is
directed toward stopping the inflammation process
by suppressing the immune system.
