[Value of steroid receptors assessment in atypical endometrial hyperplasia].
To evaluate if the immunohistochemical assessment of steroid receptors is helpful in distinguishing Atypical Hyperplasia from Well Differentiated Endometrial Carcinoma, the morphological and immunohistochemical features for steroid receptors were studied in 46 cases of atypical hyperplasia alone or associated with other degrees of hyperplasia or adenocarcinoma. The estrogen and progesterone receptors were determined by the avidin-biotin complex technique using monoclonal antibodies on paraffin embedded tissue. The diagnosis of atypical hyperplasia was based on the observation of epithelial atypias and the absence of the stromal invasion. The positive reaction for steroid receptors was moderate, very variable from case to case, heterogeneous and quite similar to that observed in carcinoma. The morphological identification of the stromal invasion is the most reliable criterion in differentiating endometrial carcinoma from atypical hyperplasia. The steroid receptors assessment is not valuable in this purpose but may be useful in cases in which a hormonal therapy is recommended.
