Incidental finding of adenocarcinoma in a gallbladder lumen with no wall involvement.

Gallbladder cancer (GBC) is a rare disease characterized by its aggressiveness. Resection with free tumour margins is the sole curative treatment and, in incidental findings, surgical reapproach is recommended for segmentectomy IVb and V or wedge resection of the gallbladder fossa and lymphadenectomy. Here we report a case of gallbladder adenocarcinoma as an incidental finding in a fragment in its lumen with no wall involvement evidentiated. The patient was reoperated for resection of the gallbladder bed with hepatic hilum and cystic duct lymphadenectomy, later evidentiated as free of residual disease. The normality of the bile ducts evidenced by imaging studies, in addition to signs of chronic cholecystitis corroborate to GBC diagnosis. We suspect that the fragment was detached gallbladder polypoid neoplastic lesion. Despite the lack of clinical manifestations, the fast surgical interventions and the histopathological analysis of the material was probably a prognostic determinant for the patient.
