It is defined as a lesion composed of smooth muscle-like stromal cells with a central cavity lined with endometrial type epithelium. There are three theories on the pathogenesis of ULMs which we discuss along with clinical presentation, diagnostic features, treatment options and potential oncological implications of this type of tumour, based on our case, and the review of the literature.
