A term that has been used to describe abnormal cells that come from glands in the walls of the cervix (the lower, narrow end of the uterus). These abnormal cells are found in a small number of Pap smears (a procedure used to detect cervical cancer) and may be a sign of more serious lesions or cancer. The term used now is atypical glandular cells. Also called atypical glandular cells of uncertain significance and atypical glandular cells of undetermined significance.
