[Synchronous double primary ovarian tumor in situ].

BACKGROUND: Afinding of primary malignancies of different histological nature in each ovary is a particularly interesting condition since the information available about it is scarce and because there is hardly any consensus about its definition, classification and proper diagnostic-therapeutic approach.

CLINICAL CASE: A case of a 49-year-old female patient presenting an abdominal mass with irregular 10 x 10 cm edges that comprises the area between the left illiac fossa and the umbilical scar. An exploratory laparatomy revealed two masses; a 15 cm cystic one in the left ovary, and an 8 cm one in the right ovary. The following histopathological analysis revealed a bilateral papillary carcinoma. A full oncogy-necological surgical protocol for ovarian carcinoma was applied. The last histopathological analysis revealed a clear cell carcinoma in the left ovary, and a moderately differentiated endometrioid carcinoma in the right one.

CONCLUSIONS: A rare case of a synchronous double primary ovarian tumor is reported. Its clinical presentation, diagnosis, treatment and follow-up pose a particular classification issue.
