Primary malignant tumors in the retrovesical region are extremely rare and are scarcely any in childhood. In the vast majority of the reported cases designated as primary malignant tumors of the seminal vesicles, Lazarus agreed with Young in view of the point that, in general, sarcomas should be regarded as primary malignant tumors of the retrovesical region involving the vesicles rather than as primary intrinsic of the vesicles, since in most cases it is impossible clinically, autoptically, or histologically to determine the exact point of origin, for these cases are usually advanced at first sight, with involvement of the vesicles, prostate and surrounding tissues. And they regarded it to start in the retrovesical connective tissue above the prostate and between the seminal vesicles Mesonephroma was reported in several articles concerning of a certain type in ovarian lesion by Schiller that he believed it originated from the remnants of mesonephric duct Later Saphir reported a few cases of clear cell adenocarcinoma of the ovary which he believed to be identical to renal tumors. This report is based upon such cases of a large liposarcoma(7 X 6 X 6 cm) in a 6-month-old male and mesonephroma in a 1-year-old female arising from retrovesical region.

A female patient with ages of 16 hospitalized due to the pain in the right of inferior costal region and the tumor in the posterior peritonium determined by ultrasound and CT scanner. The results of position AFP allowed to diagnose the preoperative germ cell tumor in the posterior peritoneum. The results of microscopy allowed concluding that this was yolk sac tumor. This study suggested that it should test the markers of tumor such as AFT and HCG to diagnose the nature of germ cell tumors. The disease can respond to radiation and chemotherapy.

Yolk sac tumor is the second most common subtype of ovarian germ cell tumors and is rare in postmenopausal women. The few cases in literature have found that in this age group, yolk sac tumors more commonly present as a mixed component, combined with epithelial tumors. We report a case of a 60-year-old female who presented with an enlarging abdominopelvic mass. Imaging pointed to an ovarian new growth. Total abdominal hysterectomy with bilateral salpingo-oophorectomy revealed a tumor with three populations composed of carcinomatous, sarcomatous, and germ cell components, which was ultimately diagnosed as an ovarian carcinosarcoma with concurrent yolk sac tumor based on histomorphology and immunohistochemical staining. This report also discusses the proposed pathogenesis, treatment, and prognosis of this uncommon entity.
