Image Description
Note the benign appearance of the tubal epithelium lining the gland. The differential diagnosis of adenosarcoma includes adenofibroma and endometrial polyp. The presence of moderate to severe cytologic atypia in stromal cells, periglandular cuffing, and at least 2 mitoses/10HPF favor adenosarcoma. Adenosarcoma arising in the cervix has to be differentiated from embryonal rhabdomyosarcoma.
