Atypical polypoid adenomyoma and hysteroscopic endometrial ablation.

A 49-year-old woman presenting with menometrorrhagia underwent an office endometrial biopsy that indicated features suspicious for atypical polypoid adenomyoma (APA) but was inconclusive. The woman requested further evaluation prior to consenting to a hysterectomy and bilateral salpingo-oophorectomy. Hysteroscopy demonstrated a fleshy 2 cm to 3 cm sessile polypoid tumour, which was resected with the entire endometrium. The histology confirmed APA. Although amenorrhea was achieved, the gynaecological oncologist recommended the woman undergo hysterectomy, which she did 4 months later. Pathologic examination of the uterus revealed no residual endometrium or APA. As this tumour generally occurs in premenopausal women, and as conserving fertility potential may be an important consideration, hysteroscopic resection of such tumours may be a therapeutic option in women who wish to retain their uterus or who would be at high medical risk for hysterectomy. However, close, intermittent postoperative surveillance is recommended.
