Abstract
We studied the relationship between steroid receptors (SR) and various stromal parameters in 100 breast cancers. Each specimen was submitted to SR determination by the dextran-coated charcoal assay and to histologic examination. No relationship was found between the presence of SR and necrosis or fibroblastic cell content. There was an inverse correlation between SR positivity and the extent of lymphocyte infiltration (p < 0.05). ER + PR + status was strongly correlated with marked productive fibrosis (PF) (p < 0.005). When SR were separately assayed, only the presence of PR was correlated with PF (p < 0.005); similar results were obtained for PR levels (p < 0.01). PF was also associated with a higher nuclear grade (p < 0.001). In conclusion, in this study a strong correlation between PR positivity or concentration and extent of PF was demonstrated in breast cancer. Since PR synthesis is an expression of an intact regulatory pathway, our data suggest that stromal production in breast cancer is related to the degree of differentiation of malignant epithelial cells.

Abstract
Two hundred human breasts removed for clinical cancer by radical mastectomy were analyzed to determine whether apocrine metaplasia and apocrine cysts have predilective sites in the four mammary quadrants. One block of tissue randomly removed for each quadrant was examined in one or more histologic sections. The results showed a concentration of apocrine metaplasia and apocrine cysts in the lower mammary quadrants (17.5% versus 8.2%), which is highly significant (x2 = 15.25; P < 0.001). The different distribution between breast cancer (showing predilection for the upper quadrants) and apocrine metaplasia is emphasized, together with the higly significant association between apocrine metaplasia and breast cancer. Based on these data, the usefulness of the clinical detection of cysts in the lower mammary quadrants and needle aspiration of their fluid for the morphologic or biochemical diagnosis of apocrine metaplasia in the screening and management of women at risk is suggested.
