Adenoid basal/adenoid cystic carcinomas of the uterine cervix: A rare hybrid tumour

Abstract

Adenoid basal carcinomas (ABCs) and adenoid cystic carcinomas (ACCs) of the uterine cervix are rare epithelial tumours which each account for less than 1% of cervical malignancies.1 The tumours have similar and overlapping morphological features but different biological behaviours: ABC has an indolent clinical course and excellent prognosis, whereas ACC can be aggressive and fatal, making accurate differentiation important. In addition, both tumours have a propensity to be mixed with numerous other malignancies, further complicating diagnosis, and have also been described as occurring as an overlap tumour.
