Abstract
In a case of urticaria pigmentosa, histopathological and electron microscopical observation of skin lesions before and after dermatographism were compared. The results showed that the shape, membranes, nuclei and granules of mast cells in the lesions before and after dermatographism are different. The prognosis, the clinical significance of dermatographism test and the pattern of degranulation in urticaria pigmentosa are discussed.
