Cancer of the supernumerary ovary in Mayer-Rokitansty-Kuster-Hauser Syndrome: A case report

초록

Mayer-Rokitansty-Kuster-Hauser (MRKH) syndrome is a Mullerian anomaly that presents with varying degrees of uterovaginal aplasia and is secondarily associated with cervicothoracic, auditory and skeletal anomalies. However, MRKH syndrome patients have normal and functional ovaries. A supernumerary ovary is an extremely rare form of an ectopic ovary and there are no reported cases of MRKH syndrome with cancer of the supernumerary ovary in the current literature. A 31-year-old female with a history of MRKH syndrome that was diagnosed 4 years previously presented with abdominal pain and a suspected malignant pelvic mass was identified. During the staging surgery, both ovaries were separated from the main mass, observed and removed. A third ovary was discovered in the pelvic mass and the diagnosis of primary ovarian cancer from the third ovary was confirmed by immunohistochemistry. We report the first known case of cancer of the supernumerary ovary in a patient with MRKH syndrome. Although both ovaries were confirmed to be normal in the patient with MRKH syndrome, we propose that an ovarian neoplasm should be considered in the diagnosis of a pelvic mass.
