A case of @entity31936 with ring Y chromosome is reported. The @entity1 was a 3-year-old @entity1 with @entity2650 and @entity246 . Culture of peripheral lymphocytes demonstrated a chromosomal mosaicism of 45 X/46 X, r (Y). Moreover, the chromosomal study with high resolution Q-band method revealed the presence of double ring Y (ring Y and double ring Y with the ratio of 25: 5). A well-developed @entity8376 was discovered by retrograde cystourethrography. @entity5274 were absent at exploratory laparotomy. The gonads existed in the scrotum on the left side and in the inguinal pouch on the right. Both gonads were proved to be testes histologically, but bilateral was deferens were absent and its remnant was found in the retroperitoneal cavity. Plastic surgery for the @entity790 was performed. Only 30 cases of ring Y chromosome have been reported in the world including our case and we briefly reviewed these cases.
