Abstract

Primary ductal adenocarcinoma of the lacrimal gland is a neoplasm morphologically similar to ductal carcinoma of the salivary gland and breast. The tumor is very rare and has not been previously reported in Korea. We report a primary ductal adenocarcinoma of the lacrimal gland in a 75-year-old man. Computerized tomography showed a 1.5 cm-sized poorly demarcated nodule in the left upper eyelid. Microscopically, the tumor showed features similar to those of intraductal and invasive ductal carcinoma of the breast, including comedonecrosis. Therefore, ductal carcinoma rather than ductal adenocarcinoma appears to be a more appropriate term for these tumors.
