Resumen

LAGUNA OLMOS, Mariano et al. Ovarian and endometrial synchronous endometrioid carcinoma. Rev. chil. obstet. ginecol. [online]. 2020, vol.85, n.3, pp.263-269. ISSN 0048-766X.  http://dx.doi.org/10.4067/S0717-75262020000300263.

Background:

there is a demonstrated association between endometriosis and some epithelial ovarian carcinoma histologies. On the other hand, it has been observed that up to 30% of ovarian neoplasms present concomitantly with endometrial neoplasms. To consider synchronicity between these neoplasms, they must meet strict pathological criteria such as those described by scully.

Objective:

to introduce a case of an ovarian and endometrial synchronous endometrioid carcinoma implanted on endometriosis sites, as well as its diagnosis and management.

Clinical case:

a 27-year-old patient who consulted because of an intermenstrual spotting. The ultrasound image showed an endometrial polyp. Furthermore, a 42 mm left adnexal trilobal tumor with a 17×15mm solid pole was described. She underwent a hysteroscopic polypectomy and laparoscopic ovarian cystectomy. Likewise, resection of a suspicious implant in the posterior vaginal fornix was done. The pathological result of the surgical pieces was: endometrial polyp with complex hyperplasia with atypia and focal points of grade I endometrioid adenocarcinoma; the left ovarian cystectomy: endometriotic cyst with focal points of endometrioid adenocarcinoma. The peritoneal lesion corresponded to a grade I endometrioid adenocarcinoma implant.

The study of the pathological characteristics and the presence of the peritoneal implant suggest the diagnosis of endometrioid ovarian carcinoma originated in a synchronous endometriotic lesion with endometrial endometrioid carcinoma.

Conclusion:

differential diagnosis between the synchronicity or spread of ovarian and endometrial endometrioid cell line carcinomas, is a great challenge and it is essential for the correct management of these neoplasms
