Polypoid endocervical adenomyoma of the uterus; A case report with MR imaging and pathological analyses

摘要

Abstract A case of polypoid endocervical adenomyoma in the uterine cervix was encountered in a 56-year-old woman. A well-circumscribed polypoid tumour was observed protruding from the uterine cervix. Based on the findings of MR imaging, the patient was assumed to have an adenoma malignum in the uterine cervix. The tumour was composed of a mixture of endocervical type proliferating glands and fascicles of smooth muscle. No distinct nuclear anapla-sia, architectural abnormality, or evidence of destructive stromal invasion was observed. In our case, the tumour was a well-circumscribed polypoid lesion, with no cytologic abnormality, thus suggesting polypoid endocervical adenomyoma. The result of ancillary diagnostic modalities should be interpreted with caution and combined with gross and light microscopic findings.
