Abstract
Gallbladder adenomyoma/adenomyomatous nodule/adenomyomatosis is a benign condition characterized by mucosal invaginations within the gallbladder wall with or without proliferation of smooth muscle fibers. Gallbladder adenomyoma is often asymptomatic and discovered incidentally during imaging studies performed for other unrelated conditions. It can mimic malignancy on radiological findings, creating a diagnostic dilemma. The management and outcome of adenomyoma and malignant lesions of gallbladder are completely different. We present here a rare case of 52-year-old female diagnosed with gallbladder adenomyoma in histopathological examination highlighting the insights into this benign distinctive condition. Therefore, it is essential to completely understand the pathognomonic and histopathological features of gallbladder adenomyoma in order to accurately diagnose this condition.
