ESR1 and neoplasm: The expression of ER and PR in EMRCs was heterogeneous; the percentage of cases with a weak/negative ER expression (score 1–2) did not significantly differ between EMRCs (8/20, 40%) and associated neoplasia (6/20, 30%) (p = 0.741); PR showed a score 1–2 in 14/20 EMRCs (70%) and 9/20 associated neoplasia (45%), with no significant difference (p = 0.200).
