microinvasive carcinoma

mi·cro·in·va·sive car·ci·no·ma

a variety of carcinoma seen most frequently in the uterine cervix, in which carcinoma in situ of squamous epithelium, on the surface or replacing the lining of glands, is accompanied by small collections of abnormal epithelial cells that infiltrate a very short distance into the stroma; this represents the earliest stage of invasion.
