The risk of a gonadal tumor is high in testicular disorder of sexual development (DSD) with the Y chromosome, but cases of DSD without the Y chromosome are extremely rare. We reported a gonadal tumor in a phenotypically male individual with 46, XX testicular DSD. A testicular tumor was incidentally found in a 32-year-old phenotypic male who was presented to the hospital with male infertility. A diagnosis of 46, XX testicular DSD was made by the presentation of karyotype analysis of 46, XX with the sex-determining region of the Y chromosome (SRY) positive and gonadal tissue without female gonads. Surgery was performed due to a gradually growing tumor. The partial orchidectomy was performed with the diagnosis of a benign Leydig cell tumor in frozen biopsy.
