Abstract:
Objective To explore the clinicopathological characteristics,immunohistochemical phenotype and differential diagnosis of ovarian seromucinous borderline tumor.Methods Fifteen cases of ovarian seromucinous borderline tumor in Shanxi Provincial People's Hospital from January 2013 to May 2017 were collected.The surgical specimens were observed after HE and immunohistochemical staining,the patients were followed-up,and the relevant literature was reviewed.Results The age of 15 cases of ovarian seromucinous borderline tumor ranged from 26 to 56 years(mean 37 years).Eight cases occurred in the right,5 cases occurred in the left,only 2 cases were bilateral tumors.The complaint of most patients was abdominal distention,3 cases was ascites.The maximum diameter of these tumors ranged from 4 to 13 cm(mean 9.3 cm).Grossly,15 cases mainly showed cystic performance,varying amounts of papillae inside wall of the cysts.Small region of 2 cases were solid.Microscopically,9 tumors were composed of endocervical-like mucinous epithelium,4 tumors were endocervical-like mucinous epithelium and serous epithelium.2 cases were accompanied with endometriosis.Tumor cells mainly expressed estrogen receptor(ER),progesterone receptor(PR),paired box gene protein 8(PAX-8),cytokeratin 7(CK7),these markers were immunophenotypes of Mullerian tumors.Followed up for 3 to 24 months(mean 16.7 months),2 cases showed bilateral tumors,1 case was peritoneal implantation.No tumor recurrence was found in the remaining 12 cases.Conclusions Different from mucinous borderline tumor,ovarian seromucinous borderline tumor possesses relative special clinicopathological features,morphological and immunohistochemical phenotypes,with better prognosis.Combination of immunohistochemical markers ER,PR,PAX-8,CK7,CK20,Vimentin,CDX-2 and WT-1 can make an accurate diagnosis of this tumor.
