We report a 20 year old case of partial androgen insensitivity syndrome, referred to our clinic with complaints concerning external genital organs and left undescended testicle. The phenotypically male case was first evaluated for secondary sex development. Axillary hair was scanty and no pubic hair was found. There was no breast development. In the gynecological examination, the clitoris was hypertrophic (4.6 cm) and a blind vagina with intact hymen was seen. Abdominopelvic ultrasonography revealed the absence of an uterus and adnexes which was supported by magnetic resonance imaging (MRI). There was a palpable mass in the left inguinal canal (cryptorchism), seen as atrophic tissue under the skin in MRI. Although the other testis was in the labioscrotal fold, it was atrophic. The Karyotype was 46 XY after genetic investigation.
