Testicular seminoma after the complete remission of extragonadal yolk sac tumor : a case report
BACKGROUND: Between 2% and 5% of malignant germ-cell tumors in men arise at extragonadal sites. Of extragonadal germ cell tumors, testicular carcinoma in situ (CIS) are present in 31–42% of cases, and CIS are reported to have low sensitivity to chemotherapy in spite of the various morphology and to have a high likelihood of developing into testicular tumors. A testicular biopsy may thus be highly advisable when evaluating an extragonadal germ cell tumor. CASE PRESENTATION: A 36-year-old man was diagnosed as having an extragonadal non-seminomatous germ cell tumor, that was treated by cisplatin-based chemotherapy, leading to a complete remission. In the meantime, testicular tumors were not detected by means of ultrasonography. About 4 years later, a right testicular tumor was found, and orchiectomy was carried out. Microscopically, the tumor was composed of seminoma. CONCLUSIONS: We herein report a case of metachronous occurrence of an extragonadal and gonadal germ cell tumor. In the evaluation of an extragonadal germ cell tumor, a histological examination should be included since ultrasonography is not sufficient to detect CIS or minute lesions of the testis

Leiomyoma in Retzius’ space: An unusual location
We report the case of a 54-year-old woman who presented to our hospital with microscopic hematuria. An imaging study revealed a tumour in the Retzius’ space. The tumour was surgically removed by an abdominal approach. Pathological examination revealed aleiomyoma. This case demonstrates a leiomyoma in an unusual location.</jats:p
