Rare tumors of the gallbladder: Clear cell carcinoma

IntroductionGallbladder cancer is a rare tumor in the gastrointestinal tract has poor prognosis, low survival and is difficult to diagnose. The most common type of gallbladder cancer is adenocarcinoma, and the incidence of clear cell carcinoma is low. Mostly, it is difficult to determine whether the isolated tumor is a primary tumor in the gallbladder or a metastatic tumor from another region. Before accepting a clear cell carcinoma as a primary gallbladder tumor, the kidneys and other possible secondary focuses are clinically considered in terms of metastases.Presentation of caseHere, we present a rarely seen case of gallbladder clear cell carcinoma, which was diagnosed by pathological examination after the surgery.DiscussionPrior to establishing that clear cell carcinoma is a primary gallbladder cancer, it is appropriate to clinically investigate possible secondary focuses, in particular the kidneys in terms of metastasis.ConclusionOur goal in presenting this case was to emphasize the importance of taking an accurate medical history in patients with clear cell carcinoma, a rarely seen gallbladder cancer.
