[Fibrocystic disease of breast and pituitary-thyroid axis function]

The aim this study was to report findings on the concentrations of mean triiodothyroxine (T3), thyroxin (T4), thyroid stimulating hormone (TSH) and prolactin (Prl) in patients with benign mastopathy and in control group. All of the examined subjects were clinically euthyroid. The mean T4 concentrations in women with mastopathy (78.25 +/- 15.27 ng/ml) were significantly lower than in control group 88.73 +/- 15.27). The mean TSH and PRL concentration in women with mastopathy were higher, but not significantly, than in control women. This results indicate, that benign mastopathy seems to be connected with thyroid functions.
