Hepatoid adenocarcinoma (HAC) is a rare extrahepatic malignant tumor that exhibits histological features resembling those of hepatocellular carcinoma. It is typically accompanied by an abnormal elevation in serum alpha - fetoprotein (AFP) levels. HAC can occur in multiple organs, with the stomach being the most common site. It has also been reported in organs such as the esophagus, colon, pancreas, lung, ovary, and uterus. After reviewing the relevant literature, to date, there have been no reports of primary HAC in the vagina. This article presents the first case of primary vaginal hepatoid adenocarcinoma.
