ABSTRACT
Changes of histopathological findings with time were studied after scratching the skin of 37 patients with dermographism. Biopsies were also done in 13 normal healthy controls for comparison with unstroked skin of the patients. 1. Biopsies of unscratched skin of the patients showed no histologic difference from those of the skin from controls. 2. Neutrophils increased in number with time after scratching and maximum neutrophil count (mean 16.08+/-24.17/HPF) was observed at 90 minutes after scratching 3. Eosinophilic infiltration was also similar to that of neutrophils. Maximum eosinophil count (mean 324+/-4.76/HPF) was found at 60 minutes after scratching. 4. L ymphohistiocytic infiltration showed a similar tendency to that of neutrophils, but the degree of change was not so prorninent. 5. Before scratching, mast cell count in patients with dermographism showed no difference in number when compared with norrnal controls. In patients with dermographism, mast; cell count inclined to decrease after scratching. 6. Edema and lymphatic dilatation in the upper dermis were most prominent at 5 minutes after scratching and disappeared slowly thereafter.
