Kimura Disease

Kimura disease is a rare, noncancerous, chronic condition that causes the tissue under the skin of the head or neck to become swollen. Masses generally appear in a person's mid-20s and the disease mainly affects Asian men. Kimura disease is diagnosed by a surgical biopsy and the cause of the disease is unknown. Treatment includes surgery, medication, or a combination of the two.  However, the masses tend to develop again after treatment. Because this condition rarely causes health problems, people with Kimura disease have a good outcome.
