Abstract
Introduction and importance
Gallbladder cancer has a poor prognosis. Therefore, an accurate diagnosis is required, for which various tests are performed. However, in some cases, it is difficult to distinguish between benign and malignant diseases before surgery. Papillary hyperplasia of the gallbladder is known for its secondary changes. Papillary hyperplasia of the gallbladder, which is known for its secondary changes, is a benign disease. We encountered papillary hyperplasia of the gallbladder with morphological changes over the course of 1 year. In addition, the tumor was suggested to be malignant during various examinations. We present a case of papillary hyperplasia of the gallbladder showing an increasing tendency and findings indicative of malignancy on imaging.
Presentation of case
A 70-year-old man underwent routine abdominal ultrasonography every year. We observed that the gallbladder wall was thickened. The tumor size was 24 mm. FDG-PET and other examinations indicated malignancy requiring surgery.
Clinical discussion
Accurate diagnosis of gallbladder tumor is difficult only by diagnostic imaging. There are problems with preoperative cytology and histology. FS can be an important test to avoid extended surgery.
Conclusion
We report a rare case of papillary hyperplasia of the gallbladder, which was difficult to diagnose. Even when morphological changes and imaging findings suggest malignancy, similar findings could appear in papillary hyperplasia of the gallbladder owing to chronic inflammation.
Gallbladder cancer has a poor prognosis.
It is difficult to distinguish between benign diseases before surgery.
Papillary hyperplasia of the gallbladder shows secondary changes.
Papillary hyperplasia of the gallbladder can be confused for a malignancy.
