Hepatoid Carcinoma of the Ovary: Case Report, Clinical Management, and Insights From Literature Review

open access: yesClinical Case Reports, Volume 13, Issue 12, December 2025.
ABSTRACT Hepatoid carcinoma of the ovary (HCO) is an exceedingly rare epithelial ovarian malignancy demonstrating hepatocellular differentiation and marked serum AFP elevation. Due to its rarity, existing literature remains limited, and optimal management strategies remain undefined. Emerging evidence highlights the urgent need for improved recognition
