A blood lipid profile and other tests may be done to determine the underlying condition responsible for the appearance of xanthomas.
Treating xanthoma consists of treating and controlling the underlying health conditions that cause the fatty deposits to develop. Better control of the metabolic disorders that can lead to xanthoma can reduce their occurrence.
Xanthomas can recur after treatment.
Other treatment options for xanthomas include:
Surgery may be used to remove the fatty deposits. However, even after a xanthoma is surgically removed, it can return.
Laser surgery with CO2 laser, pulse-dye laser, or Erbium-YAG laser can be performed.
Treatment with trichloroacetic acid may also be used to treat xanthomas.
