Uterine Teratoma (Dermoid cyst) Presenting as an Endometrial Polyp.

Abstract

On the initial diagnostic hysteroscopy, the lesion appeared as an endometrial polyp [Figure 1]; however, on resection of the lesion, fatty tissue was identified in its core [Figures 2 and 3 and Supplementary Video 1]. There was no evidence of uterine perforation. Histology was reported to be a mature benign uterine teratoma. There were areas of adipose tissue, neural tissue, bone and cartilage, as well as hair-bearing squamous epithelium.
