Purpose Exogenic adenomyoma of the cervix is very rare. To date, very few cases have been reported, and the presentation and diagnosis are not clear. The aim of this study was to present 2 cases of exogenic adenomyoma of the cervix and summarize what is known about this disease by conducting a literature review of reported findings. Methods The clinical data from 2 cases of women with exogenic adenomyoma of the cervix admitted to Peking University First Hospital were analyzed retrospectively, and a systematic literature review was carried out. Results In our cases, exogenic adenomyoma of the cervix presented as a mass with mixed solid and cystic lesions in the pelvis and could not be separated from the cervix. Postoperative examination of the surgical specimen using pathological tests confirmed the tumors were composed of a proliferation of endocervical glands and smooth muscle, based on which exogenic adenomyoma of the cervix was confirmed. Conclusions Exogenic adenomyoma of the cervix should be considered in the diagnosis, in cases of mixed solid and cystic pelvic masses found in close relationship with the cervix.
