fibroma
A benign tumor consisting of a mass of
connective tisue cells that have a spindle shape.
fibroma, cemento-ossifying
A reactive lesion
of the gingiva that may grow to very large size,
unless treated. Abbreviated COF. A COF has a hard,
fibrous consistency. Treatment is surgery. Also
known as ossifying fibroma.
fibroma, collagenous
See 
fibroma, desmo-
plastic.
fibroma, desmoplastic
A rare type of primary
bone tumor that is characteristically composed of
well-differentiated cells that produce collagen.
Desmoplastic fibromas are discovered most often in
the first three decades of life, in the mandible (the
femur and pelvis are also favored sites). Although
benign, these tumors infiltrate locally and may
cause pain and swelling or fluid accumulation.
Treatment is surgical removal, but desmoplastic
fibromas may recur. Also known as collagenous
fibroma.
fibroma, ossifying
See 
fibroma, cemento-
ossifying.
fibromatosis
A condition characterized by mul-
tiple fibromas. See also 
fibroma.
fibromyalgia
A disease characterized by chronic
pain, stiffness, and tenderness of muscles, tendons,
and joints, without detectable inflammation.
Fibromyalgia does not cause body damage or defor-
mity. However, undue fatigue plagues 90 percent of
patients with fibromyalgia. Sleep disorder is also
common in patients with fibromyalgia. Fibromyalgia
can be associated with other rheumatic conditions,
and irritable bowel syndrome (IBS) can occur with
fibromyalgia. There is no definitive medical test for
the diagnosis of fibromyalgia, so diagnosis is made
by eliminating other possible causes of the symp-
toms. The most effective treatment is a combination
of education, stress reduction, exercise, and med-
ication. Formerly known as fibrositis.
fibrosarcoma
A malignant tumor consisting of
fibroblasts (connective tissue cells that produce the
collagen found in scar tissue) Fibrosarcoma may
occur as a mass in the soft tissues or may be found
in bone. An infantile form of fibrosarcoma which
occurs in children less than one year of age has an
excellent prognosis when appropriately treated.
Symptoms may include a lump or mass with or with-
out associated pain and soreness.
