遗传性血小板疾病占遗传性出血疾病的首位(36%)。典型病例诊断并不困难,隐匿的和不典型病例诊断困难,常表现在外伤后或手术后引起大量出血。一般的血小板疾病诊断方法(血小板数量、形态、功能检查)常不能作出正确的诊断。作者观察17例6～14岁患出血性疾病患儿,男8例,女9例,其中有遗传性疾病者10例。全部患儿首次发生出血症状均在3岁以后。7例有轻度出血既往 Hereditary platelet disease accounted for the first hereditary bleeding disease (36%).

All children with first symptoms of bleeding are after 3 years of age. 7 cases had mild bleeding in the past
