The association of Sertoli-stromal cell tumor with testicular feminization syndrome (TFS) has been elaborated in the past studies. Here, we described immunohistochemical studies on Sertoli cell tumor of the gonad in a TFS patient and compare with 2 other cases of spontaneous ovarian Sertoli-stromal tumor. [Case 1] The case was a 73 year-old Japanese patient (46XY karyotype), who had had primary amenorrhea. High level of testosterone was noted in laboratory investigation (1900 ng/ml). No ambiguous morphology of external genitalia was present, but atrophy of vagina was noted. The patient was diagnosed as TFS. A left gonadal tumor was identified histologically showing well differentiated Sertoli cell tumor. The tumor cells were positive for anti-vimentin antibody but negative for anti-keratin, EMA and p53 antibodies by immunohistochemistry. The right gonad was an immature testis. [Case 2] The case was a 33 year-old female with ovarian Sertoli-Leydig cell tumor. Immunohistochemically, positive reaction for anti-keratin and p53 antibodies were observed. [Case 3] The case was a 17 year-old female with moderately differentiated Sertoli cell tumor of the ovary. The tumor cells were positive for anti-keratin, EMA and p53 antibodies by immunohistochemistry. Difference in immunohistochemical reactions between Sertoli cell tumor in TFS and Sertoli-stromal cell tumors of the ovaries was probably due to variation in the degree of gonadal development.
