[Endometrial adenofibroma]

We report a case of papillary adenofibroma of the uterine corpus in a 31 year-old woman who was initially examined for vaginal bleeding. Pelvic examination showed a large polypoid mass protruding through the cervix canal. A pelvic ultrasound revealed a polypoid cystic mass apparently arising from the uterus. A polypectomy was performed. The tumor was composed histologically by begin epithelial and mesenchymal components. Uterine adenofibroma is a extremely rare tumor which considered to be a mixed tumor of Müllerian origin. This lesion appears to be clinically and histologically benign but must be differentiated from other malignant lesions of the uterus, particularly from the adenosarcoma.
