An abnormal extra band on the short arm of the X chromosome was found in a 7-year-old reared as a female, of mixed gonadal dysgenesis. She had ambiguous external genitalia, scoliosis, short stature, mental retardation and motor paralysis of the limbs. Chromosomal analysis revealed the karyotype of 46,Xp+ Y. An uterus with fallopian tube, a streak gonad on the left side and a testicle on the right side were discovered at exploratory laparotomy. Bilateral gonads and fallopian tube were removed. The chromosomal analysis of her normal mother showed the presence of the same abnormal X chromosome (46, X Xp+). In the literature, we found some cases of intersexuality with Xp+ in karyotype. The relationship between our own case and these Xp+ cases was discussed briefly. Thirty-five cases of mixed gonadal dysgenesis have been reported in Japanese literature, our own case being the 36th case.

Gonadal dysgenesis and Mullerian agenesis both are common causes of primary amenorrhea. Coexistence of gonadal dysgenesis and Mullerian agenesis has been previously described as a rare event. The karyotypes, 45,XO,45,X/46,XX,45,X/46,X,dic(X),46,XX, and 46,XY, have been reported in the literature. A 22-year-old woman presented with primary amenorrhea and normal intelligence. Her physical examination confirmed the absence of breast development and axillary hair. The woman weighed 43 kg and was 150 cm tall. Scoliosis of the thoracic spine was noted on a chest X-ray film. Also, her pelvic examination revealed a vaginal introitus with a vaginal depth of 7 cm, measured by sounding. Her external genitalia were female but lacked pubic hair. The rectal examination failed to reveal a uterus. Pelvic ultrasound disclosed the absence of uterus and ovaries, and her serum gonadotropin levels were in the menopausal range (FSH, 118.59 IU/L; LH, 38.94 IU/L). Estradiol was less than 10 pg/ml. Two mosaic cell lines, 45,X (50%) and 46,X,del(X)(p22.2X50%), were found in the chromosomal study. Laparoscopic evaluation confirmed the absence of uterus and ovaries with normal fallopian tubes. Coexistence of gonadal dysgenesis and Mullerian agenesis is a rare event. The two mosaic cell lines 45,X/46,X,del(X)(p22.2) in this combination have not been reported before. In patients with this condition, estrogen will initiate and sustain maturation and function of secondary sexual characteristics, and lifelong hormone therapy will protect against osteoporosis and cardiovascular disease.
