Urticaria Pigmentosa. Presented by Dr. Harold N. Cole and Dr. J. R. Driver.
R. G., a boy aged 19 months within one month after birth had a generalized eruption which has persisted in spite of various forms of therapy. Because of the pigmented character of the eruption and the presence of lesions on the palms and soles, syphilis had been considered as the probable diagnosis by the attending physician. The child is well developed and well nourished.Distributed over the trunk and even on the palms and soles is a generalized macular pigmented (reddish brown) eruption. The primary element seems to be an elongated macule with a slightly irregular shape. Most of the macules are about the size of a split pea. On the back there are some urticarial lesions with reddish halos. Some of the areas show a suggestion of infiltration or edema. The mucosae are normal.Serologic tests
