Occult Gallbladder Carcinoma Presenting as a Primary Ovarian Tumour: a Case Report and Review of Literature.

The ovary is a common site of metastasis from various organs. However, little is known about gallbladder carcinoma metastasising to the ovaries and presenting as a primary ovarian tumour. We report a case of a metastatic gallbladder carcinoma which mimicked a primary ovarian tumour in a 31-year-old woman who presented with menstrual symptoms and an ovarian mass without obvious signs and symptoms related to gallbladder carcinoma. Postoperatively histopathological examination diagnosed primary ovarian germ cell tumour for further chemotherapy. However, postoperative re-evaluation with radiology suggested the possibility of a primary gallbladder carcinoma. Exact diagnosis could only be made after repeat histopathological evaluation of the ovarian mass.
