Adenomyomatous Polyp of the Endometrium With Prominent Epithelioid Smooth Muscle Differentiation: Report of Two Cases of a Hitherto Undescribed Lesion.
A minor component of smooth muscle may be present in the stroma of benign endometrial polyps and 2 distinctive endometrial polypoid lesions, atypical polypoid adenomyoma and adenomyoma, are characterized by stroma with a predominant smooth muscle component. In this report, we describe 2 unusual endometrial polyps in 43- and 60-year-old women in which the stromal component was predominantly composed of smooth muscle with an epithelioid appearance, a phenomenon which, as far as we are aware, has not been previously reported.
