Sex steroid receptors in Hodgkin's disease.

A case report of a dramatic therapeutic response of Hodgkin's disease (HD) to diethylstilbestrol (DES) in a man who was being treated for concurrent prostate cancer suggested that there also may be a role for sex steroids in the pathogenesis of HD (1). High levels of estrogen receptors (ER) comparable to those seen in breast carcinoma cells were detected in that patient's Hodgkin's biopsy specimen. In order to determine whether this patient was unique or whether sex steroid receptors commonly are present in HD specimens, we examined expression of ER and progesterone receptors (PR) in diagnostic tissue from pediatric (n = 14) and adult (n = 41) patients with HD using immunohistochemistry. None of the 55 samples expressed PR. 16/55 (29%) demonstrated weak nuclear ER positivity, which was confined to germinal center and occasional mantle zone lymphocytes and was comparable to that seen in non-malignant control lymph nodes. (4/5)5 (7.3%) samples exhibited moderate positivity in Reed Sternberg cells, which in one case was nuclear. ER commonly are expressed weakly in some HD tumors unrelated to clinical stage or patient sex but are generally limited to germinal center and mantle zone lymphocytes. A rare patient displays moderate cytoplasmic or nuclear ER in Reed-Sternberg cells.
