• Summary: Estrogen receptor–negative (ER-negative) endometrial carcinomas represent a biologically aggressive and heterogeneous subset of endometrial cancers. Although ER testing has long been used in endometrial carcinoma, it has historically been applied mainly for therapeutic decision-making rather than as a diagnostic tool. Loss of ER expression is associated with poor prognosis but, by itself, is insufficient for accurate tumor classification. In this commentary, we review the evolving diagnostic significance of ER negativity using an integrated framework that incorporates tumor morphology, immunophenotypic features, and molecular heterogeneity. We highlight several high-grade ER-negative tumor types—including gastrointestinal-type adenocarcinoma, pilomatrix-like carcinoma, mesonephric-like adenocarcinoma, clear cell carcinoma, and other high-grade ER-negative carcinomas—that show distinct clinicopathologic characteristics. We propose that ER negativity should be regarded as a diagnostic signal that prompts careful subclassification, with important implications for accurate diagnosis and clinical management.
