Urticaria Pigmentosa is a benign type of cutaneous mastocytosis that I occasionally encounter in both my The Woodlands dermatology and Conroe dermatology offices.  Urticaria Pigmentosa accounts for the majority of childhood mastocytosis cases.  Clinically, Urticaria Pigmentosa appears as multiple red/brown indurated papules and nodules.  Blistering can occur in the lesions especially when they are rubbed as this causes a local histamine release.  Most cases last for a few years and then spontaneously resolve prior to puberty.
