Uterine adenolipoleiomyoma: a rare hamartomatous lesion.

An apparently unique intramural uterine lesion is described for which we propose the name adenolipoleiomyoma. On gross examination, a well-circumscribed white intramural mass contained focal fatty areas. Histology showed the mass to be composed of smooth muscle, adipose tissue, and endometrial, endocervical, and tubal type glands. The endometrial glands were surrounded by typical endometrial stroma. There was no evidence of adenomyosis in the uterus outside the lesion. This is only the second report of such a lesion within the uterus and the first with an intramural location. We believe it to be a benign hamartomatous lesion.
