Mature teratoma of the uterine corpus: A case report.

We report a case of a 37-year old female with a mature teratoma of the uterine corpus presented by metrorrhagia. Grossly, the tumor was polypoid without apparent invasion into the myometrium. Microscopically, the tumor consisted of disorganized mature neural tissue intermingled with nodular foci of cartilaginous tissue, groups of seromucionous glands and ciliated columnar respiratory epithelium. Fifteen months after the diagnosis, the patient showed no signs of tumor relapse. Then she was lost for a follow-up. Teratoma of the uterine corpus is rare; to the best of our knowledge only about 20 cases have been reported to date.
