Metastatic Gallbladder Carcinoma to Pleura with Gallbladder Tuberculosis – Case Report with Literature Review

Gallbladder carcinoma (GBC) is the most common malignant tumor of the biliary system and presents with frequent locoregional lymphadenopathy and distant metastasis. Gallbladder tuberculosis (GT) is rare abdominal tuberculosis (TB). GBC and GT mimic each other. The clinical examinations and radiographic investigations sometimes fail to exhibit the difference between these two which are confirmed only after postoperative histopathological assessment. Herein, we report a patient of GBC with coexistent GT with pleural metastasis and pleural effusion. We emphasize the importance of differential diagnosis of the two conditions, with similar signs and symptoms. The pleura is an extremely rare site of spread of GBC as seen in our patient.
