Gallbladder cancer is generally diagnosed at an advanced stage. The liver is the most commonly invaded organ by direct extension and/or metastasis, followed by regional lymph nodes. Oral soft tissue metastasis is extremely unusual. This report describes the case of a 62-year-old woman diagnosed with advanced metastatic gallbladder cancer, who initially presented with abdominal pain. Diagnosis of gallbladder cancer was made about 3 months after her symptoms developed, when a laparoscopic cholecystectomy was performed because of the suspicion of gallstones. Liver metastasis was also discovered during surgery. A postoperative investigation revealed additional lung and bone metastases. A visible left gingival tumor was found on physical examination and was confirmed as gallbladder cancer metastasis by compatible histopathology 1 month after surgery. The patient responded poorly to chemotherapy and unfortunately died 5 months after the diagnosis. The clinical presentation of gallbladder cancer was relatively typical, apart from the unusual gingival metastasis. The medical literature contains quite a few examples of metastatic lesions located strictly in the oral soft tissue, however no case of gallbladder cancer metastasizing to the oral soft tissue has been previously reported.

Gallbladder carcinoma is the 5th most common gastrointestinal cancer. Gallbladder cancer preferentially metastasizes to regional lymph nodes and liver parenchyma. Bone metastases from gallbladder carcinoma are rare presentation. We report a case of gallbladder carcinoma with solitary metastasis to femur bone with surrounding soft tissue involvement, mimicking as soft tissue tumour involving bone.

Signet ring gallbladder carcinoma is a rare aggressive variant of mucinous adenocarcinoma with poor prognosis. Positron emission tomography/computed tomography (PET/CT) with Fluor18 deoxyglucose (F18-FDG) is a useful tool in the staging of gallbladder cancer. We report a 68 years old man with a surgically resected acute cholecystitis, whose biopsy was positive for signet ring cell gallbladder carcinoma. During surgery, locoregional lymph nodes, liver or peritoneal involvement were not detected. A PET/CT was performed for staging, finding multiple hypermetabolic lytic bone lesions. Percutaneous biopsy of a pelvis bone lesion, confirmed a metastasis of the tumor. In this case, the staging with PET/CT allowed the diagnosis of unsuspected bone metastases and was a useful tool for deciding the best site of biopsy for histologic confirmation.
