Clinical and pathological analysis of cellular leiomyoma arising from different parts of the uterus

Objective:To investigate the clinical features of cellular leiomyoma arising from different parts of the uterus and its prognosis.Methods:The cases of uterine leiomyoma treated in our hospital from 2000 to 2005 were reviewed retrospectively,and the incidence rate,clinical manifestation and age of onset of cellular leiomyoma arising from different parts of the uterus were analyzed.Results:Of the 1538 cases of cellular leiomyoma,the incidence of cellular leiomyoma arising from the intervallum accounted for 16.09%,from below the mucous membrane 30.69%,and from the subserosa 9.18%.The difference was significant(P0.01﹚.The median onset-age of cellular leiomyoma was 41,while the median onset-age of common leiomyoma was 47.The prognosis of both groups had no significant difference during the follow-up.Conclusions:The cellular leiomyoma of uterus prone to arise from below the mucous membrane of the uterus and the prognosis is good.
