Hepatic estrogen and progesterone receptors in an estrogen-associated hepatic neoplasm.
Słowa kluczowe
Abstrakcyjny
A patient with a benign hepatic neoplasm developing after treatment with estrogenic hormones is described. After excision, the neoplastic tissue was analyzed for the presence of cytosol estrogen and progesterone binding proteins. The neoplasm was classified as focal nodular hyperplasia of the liver and was demonstrated to contain high-affinity cytosol estrogen and progesterone hormone receptors. The estrogen-binding affinity of the neoplasm was three times greater than that of normal liver. Further investigation of cytosol hormone receptors in estrogen associated hepatic neoplasms will be required to define the role of these binding proteins in the possible etiology of certain liver tumors.
