ABSTRACT
Background and

purpose:

MMMT is known as a rare malignancy in gynecological tumor. Because of its difficulty in diagnosis and treatment, the prognosis is extremely poor. This study was to discuss the clinicopathologic feature and PRA,PRB expressions of uterine MMMT.

Methods:

We analysed clinicopathologic data and the expressions of PRA,PRB by immunohistochemical staining on 17 cases of uterine MMMT, and 11 patients were followed up.

Results:

①The patients usually presented with abnormal vaginal bleeding with no specifi city clinically. ②The morphological changes were various and complicated, including epithelial and mesenchymal components and a variety of inter-permeated and transitional tissue elements.③The positive rate of PRA in stageⅠ and stageⅡ were 66.7% and 40%, and PRB in stage Ⅰ and stageⅡwere 55.6% and 20%, respectively. ④The mean survival time in stageⅠ,Ⅱ and Ⅲ were 43.8 months (32-59), 34.25 months (19~41) and 5 months, respectively.

Conclusion:

The diagnosis of uterine MMMT was mainly based on tissue morphology; the development of uterine MMMT might be related with the loss of PRA and PRB ; the clinical stage and the expression of PRA and PRB might be the prognostic factors for uterine MMMT.
