Extrauterine adenomyoma with atypical (symplastic) smooth muscle cells: a report of 2 cases.
Adenomyomas are circumscribed tumorlike masses most often involving the uterus and consisting of endometrioid glands, stroma, and smooth muscle tissue. They are uncommon in extrauterine sites and in this situation it may be unclear whether such lesions represent foci of endometriosis with marked smooth muscle hyperplasia/metaplasia, uteruslike mass lesions, or leiomyomas with entrapped endometriotic glandular and stromal elements. In this report 2 cases of extrauterine adenomyoma are presented in which the smooth muscle component showed focal atypical (symplastic) cytologic appearances.
