Katona et al. [S34] and Izikson et al. [S35] reported AR expression in 65% (20/31) and 78% (25/32), respectively, of basal cell carcinoma cases; they suggested that the expression was high enough to help distinguish basal cell carcinoma from other skin conditions with low or negative AR expression, such as benign trichoblastic tumors and desmoplastic trichoepithelioma. The gene discussed is AR; the disease is basal cell carcinoma.
