Adenoid basal carcinoma of the uterine cervix is rare and its cell origin
is still obscure. We report a case of adenoid basal carcinoma of the
uterine cervix discovered incidentally in a 69-year-old woman who had been
hysterectomized due to endometrial adenocarcinoma of the uterine corpus.
Histologically, small round-to-oval cancer cell nests with peripheral cell
palisading were seen budding from the basal cell layer of the uterine
cervix showing carcinoma in situ. Immunohistochemically, the basaloid cells
of the adenoid basal carcinoma were positive for keratins 14, 17 and 19 and
resembled reserve cells of the cervical epithelium. The results of this
study clearly demonstrated that adenoid basal carcinoma shows a phenotype
similar to reserve cells of the uterine cervix. A review of the literature
indicated that this tumor has a favorable prognosis and should be clearly
separated from adenoid cystic carcinoma, which has a much poorer outcome.
