• Synchronous multiple primary tumors are those that are diagnosed simultaneously, among other criteria. Synchronous appearance of a carcinoma localized in the endometrium and ovary is controversial from a therapeutic and diagnostic point of view. These entities are rare; synchronous primary cancers of the endometrium and ovary are found in 10% of women with ovarian cancer and in 5% of women with endometrial cancer.

  We present a case of synchronous endometrioid adenocarcinoma with serous papillary cystadenocarcinoma of the ovary that, according to the classification established by Eifel et al., would be included in group C (composed of carcinomas of the endometrium and ovary of different histological types). The etiology is unclear and, in 45% of patients in group C, there is myometrial invasion, compared with 10% of the patients in group A (concordant endometrioid tumors of the uterus and ovary, which constitute the most frequent histological group).
