ABSTRACT
Objective:To investigate the clinicopathological features of metastatic ovarian tumors from digestive system.Methods:The clinicopathological and follow-up data of 21 patients with metastatic ovarian tumor from digestive system were collected from April 2006 to January 2020 in the Maternity Hospital of Dalian Women and Children′s Medical Group. The pathological slides were reviewed, immunostained by EnVision method, and the clinicopathological features were summarized.Results:Twenty-one cases, aging from 26 to 66 years (average 41.5 years), were treated with chief complaint of abdominal pain, menstrual disorder or pelvic mass. The incidence of bilateral ovarian tumor was 81.0% (17/21), with a diameter of 0.2 to 20.0 cm. Most of tumors were solid and cystic, nodular or lobulated. Microscopically, tumor cells diffusely infiltrated ovarian stroma, accompanied with stromal proliferation and luteinization obviously. Metastatic gastric cancers were mainly signet-ring cell carcinomas, with cytokeratin 7 (CK7) positive, tail homeobox transcription factor 2 (CDX2) and cytokeratin 20 (CK20) partially positive, paired-box gene 8 (PAX8) and special AT-rich sequence binding protein 2 (SATB2) negative; metastatic colorectal cancers were mainly characterized by atypical glands, forming single cells or cribriform structure; metastatic appendix tumors were mostly low-grade tumor cells similar to ovarian borderline tumors and abundant extracellular mucinous, accompanied by peritoneal pseudomyxoma. The CK7 and PAX8 were negative, while the CK20, CDX2 and SATB2 were positive in patients with metastatic ovarian tumor from colorectal cancer and appendix tumor. The average follow-up time was 36 months, 18 patients relapsed within 5 years, 15 patients died; 3 patients were lost to follow-up.Conclusions:The ovarian metastatic tumors from digestive system are mostly bilateral, mainly solid and cystic. Microscopically, they show diffuse interstitial infiltration of tumor cells. The diagnosis should be combined with medical history, clinical symptoms, gross and histological features of tumor and immunohistochemistry, which should be mainly differentiated from primary mucinous ovarian tumor. The overall prognosis is poor.
