The association of Ewing's sarcoma/peripheral neuroectodermal tumor and endometrioid type endometrial carcinoma has been reported relatively recently. We have recently identified Ewing's sarcoma/peripheral neuroectodermal tumor differentiation in uterine serous carcinomas and undertook this study to evaluate the frequency of both serous and endometrioid carcinomas expressing Ewing's sarcoma/peripheral neuroectodermal tumor differentiation. Seventy cases of uterine serous carcinoma were retrieved from the archival files and stained with antibodies to CD99. Positive and negative control slides were run with each staining batch. Perinuclear dot-like and/or membranous staining was regarded as positive. The frequency of Ewing's sarcoma/peripheral neuroectodermal tumor differentiation in 56 FIGO grade 3 endometrioid carcinomas was also determined and 7% uterine serous and 12.5% of FIGO grade 3 endometrioid endometrial carcinomas showed Ewing's sarcoma/peripheral neuroectodermal tumor differentiation. Given the worse prognosis associated with Ewing's sarcoma/peripheral neuroectodermal tumor differentiation, even in neoplasms already at high risk for recurrence and metastasis, a high index of suspicion for Ewing's sarcoma/peripheral neuroectodermal tumor should be maintained in high-grade uterine serous carcinomas.

BACKGROUND The risk of recurrent oncological disease due to the reintroduction of cancer cells via autotransplantation of cryopreserved ovarian tissue is unknown. METHODS A systematic review of literature derived from MEDLINE, EMBASE and the Cochrane Library was conducted. Studies on follow-up after autotransplantation; detection of cancer cells in ovarian tissue from oncological patients by histology, polymerase chain reaction or xenotransplantation; and epidemiological data on ovarian metastases were included. RESULTS A total of 289 studies were included. Metastases were repeatedly detected in ovarian tissue obtained for cryopreservation purposes from patients with leukaemia, as well as in one patient with Ewing sarcoma. No metastases were detected in ovarian tissue from lymphoma and breast cancer patients who had their ovarian tissue cryopreserved. Clinical studies indicated that one should be concerned about autotransplantation safety in patients with colorectal, gastric and endometrial cancer. For patients with low-stage cervical carcinoma, clinical data were relatively reassuring, but studies focused on the detection of metastases were scarce. Oncological recurrence has been described in one survivor of cervical cancer and one survivor of breast cancer who had their ovarian tissue autotransplanted, although these recurrences may not be related to the transplantation. CONCLUSIONS It is advisable to refrain from ovarian tissue autotransplantation in survivors of leukaemia. With survivors of all other malignancies, current knowledge regarding the safety of autotransplantation should be discussed. The most reassuring data regarding autotransplantation safety were found for lymphoma patients.
