A proportional score of basaloid cells showing the expression of androgen receptors reached 2.33 ± 0.56 in the adenoma group, 2.08 ± 0.66 in the epithelioma group and 1.40 ± 0.89 in the carcinoma group and the differences between the groups were not significant (p > 0.05). The gene discussed is AR; the disease is adenoma.
