Objective To study the clinical features and TCM syndrome distributions of pediatric allergic purpura.Methods The clinical data including gender

age

sign

duration

inducement

past medical history

history of allergy

and seasonal incidence in 100 children with allergic purpura was collected

and all the cases were divided into 5 TCM syndromes such as wind-heat damaging vessels syndrome

blood heat moving overly syndrome

stomachspleen damp heat syndrome

yin deficiency fire hyperactivity syndrome and qi failing to control blood syndrome.The syndrome distributions were analyzed according to age

season

symptom

duration and inducement.Results There were 17 patients with wind-heat damaging vessels syndrome

49 patients with blood heat moving overly syndrome

8 patients with stomach-spleen damp heat syndrome

10 patients with yin deficiency fire hyperactivity syndrome

and 16 patients with qi failing to control blood syndrome.The peak of prevalence aged from 6 to 9 years old

and the onsets occurred mainly in autumn and winter.All children had skin symptoms and 93 children had simple skin symptoms or symptoms in the skin

gastrointestinal tract and joints.There were significant differences in the TCM syndrome distributions between age

season and duration（ P < 0.05）.Conclusion The common TCM syndrome of pediatric allergic purpura is blood heat moving overly syndrome.The TCM syndrome distribution is related to age

season and duration.
