In addition, ectopic adrenal tissue must be differentiated from urogenital tumors, in particular its mimickers, such as renal cell carcinoma and Sertoli Leydig cell tumor, that also partially share the immunophenotypic markers of the adrenal cortex (Melan-A, SF-1, inhibin). The gene discussed is SF1; the disease is Sertoli-Leydig cell tumor.
