Abstract
Relationships between certain histopathologic features of tumor specimens and estrogen receptor (ER) status were investigaetd. Lobular and ductal carcinomas were richer in ER than other histologic types. Well-differentiated carcinomas were more often hormone receptor positive than poorly differentiated tumors. Lymphocytic and plasmatocytic infiltration in and around the tumor as well as elastosis also appeared to be related positively to ER status. [Therapeutic implication is considered.].
