Adenoma malignum (AM), also referred to as "minimal deviation adenocarcinoma", is an extremely uncommon variant of highly-differentiated adenocarcinoma of the uterine cervix. The study presented herein describes a case of uterine AM found out after hysteroscopy. An early-stage, well-differentiated mucinous uterine adenocarcinoma was diagnosed post-operatively. A subsequent immunohistochemical assessment of a panel of antibodies was applied, in order to distinguish between female genital tract malignancies.
