Urticaria pigmentosa

Alternative names:

mastocytoma; mastocytosis; systemic mastocytosis

Treatment:

Antihistamines may relieve some of the histamine-induced symptoms such as itching and flushing. Discuss the choice of antihistamine with your child's health care provider.

Expectations (prognosis):

Urticaria pigmentosa may resolve in 50% of affected children by puberty. Symptoms usually decrease in the other 50% as they grow into adulthood.

Complications:

Discomfort from itching, and possible self-consciousness about the "spots", are the primary complications. Other problems such as diarrhea, fainting, and so on are rare.

Calling your health care provider:

Call for an appointment with your health care provider if your child has symptoms suggesting urticaria pigmentosa.
