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.

[mī′krō·invā′siv]
Etymology: Gk, mikros + L, in, within, vadere, to go
a squamous epithelial neoplasm that has penetrated the basement membrane, the first stage in invasive cancer. See also carcinoma in situ.

microinvasive carcinoma

A superficially invasive epithelial malignancy; if you must ask, it usually isn't Uterine cervix Stage Ia carcinoma A squamous cell carcinoma–SCC that penetrates < 5 mm from the base of the epithelium or < 7 mm in horizontal spread; anything larger is Stage Ib; cervical MC has > 95% 5-yr survival; lymph nodes are involved in ±1% of MCs Vulva A SCC measuring < 2 cm in diameter, and < 5 mm stromal invasion; 5% have lymph node metastases Treatment Vulvectomy, lymph node excision if involved. See Carcinoma in situ.
