Does urticaria pigmentosa come and go?
Urticaria pigmentosa goes away by puberty in about one half of affected children. Symptoms usually get better in others as they grow into adulthood.
Can adults have cutaneous mastocytosis?
Cutaneous mastocytosis that develops after age 2 or in adults generally does not resolve. Approximately 90% of affected adults also have evidence of systemic mastocytosis at the time of diagnosis. Later onset cases also have a higher risk of malignant (cancerous) forms of mast cell disease.
Is urticaria pigmentosa curable?
No, there is no cure for urticaria pigmentosa. Childhood urticaria pigmentosa resolves by puberty in many cases. If urticaria pigmentosa started after the age of 10, there is a greater chance of progressing to systemic mastocytosis where mast cells may accumulate at sites other than the skin.
How long does urticaria pigmentosa last?
Most children will outgrow urticaria pigmentosa as they get older. There is no treatment to prevent new spots from forming. The spots may fade eventually but will usually last for years. As long as there is no systemic involvement, urticaria pigmentosa doesn’t usually need treatment.
Can urticaria leave scars?
Hives typically do not leave a mark or scar and are not painful. Hives can occur in any location, but if they occur in some areas, such as the eyelid or ear, they can appear to be very swollen. They can also be associated with other areas of swelling, also called angioedema. Hives (urticaria) can be acute or chronic.
How do you test for urticaria pigmentosa?
How Is Urticaria Pigmentosa Diagnosed?
- Blood count, which will provide more information about the types and amounts of different cells in your blood.
- Serum tryptase, which tests for an enzyme that’s released from mast cells.
- Bone density scan, which shows how strong and thick your bones are.
