This report describes a case of a patient with a large solid gallbladder
adenocarcinoma that was completely resected through aggressive surgery. The patient was a 57-year-old woman who had been diagnosed with advanced
gallbladder cancer, had no indications for surgical resection and was scheduled to undergo systemic
chemotherapy. She presented to our hospital for a second opinion. At the time of assessment, her
tumor was large but was well-localized and had not invaded into the surrounding tissues, indicating that surgical resection was a reasonable option. Subsequently, the
tumor was completely extracted via right
hepatectomy with en bloc resection of the caudate lobe and extrahepatic bile duct. Histopathologically, the
tumor was a solid
adenocarcinoma. Although there are relatively few reports in the literature regarding solid gallbladder
adenocarcinoma, well-localized growth appears to be a characteristic feature. On the basis of a
tumor's progression behavior, aggressive surgical treatment might be indicated even when the
tumor has grown to a considerable size.
