[A case of atypical polypoid adenomyoma with intramural myoma-like growth].

We encountered a case of a large atypical polypoid adenomyoma (APA) which showed characteristic intramural appearance. As many cases of APA of the uterus have been reported in recent years, macro- and microscopic findings of the lesion and its clinical characteristics have been investigated. However the pathogenesis and the natural history of the lesion remained to be solved owing to still limited number of the cases. We report this case to discuss the macroscopic findings and clinicopathologic characteristics of the lesion.
