Metastatic Gallbladder Adenocarcinoma to the Endometrium: A Case Report and Review of Literature.

Gallbladder carcinoma (GBC) metastasis to the uterine cervix is very rare, accounting for less than 10 reported cases. GBC is an uncommon neoplasm with a poor prognosis. Many patients remain asymptomatic until it reaches an advanced stage or discovered incidentally. Most metastatic diseases occur in the lung, liver, and bones. We report a case of a patient treated for GBC with a good clinical response, who presented with metastasis in the uterine cervix. Uterine cervix metastasis from any extragenital primary is rare and poses a radiologic, pathologic, and clinical diagnostic challenge. Here, we review and discuss the published literature on uterine cervix metastasis from extragenital sources. Gynecologic clinicians should be wary of these rare presentations of metastatic disease, as the diagnosis can alter the management.
