Mucoepidermoid carcinoma (MEC) is a malignant epithelial neoplasm composed of varying proportions of mucous, epidermoid, intermediate, columnar, and clear cells and often demonstrates prominent cystic growth. MEC is usually subclassified as low, intermediate, or high grade on the basis of its histologic features, including the presence of cystic spaces, cellular differentiation, proportion of m...

Histologic grading schemes for canine inflammatory conditions are sparse, and in the case of the canine pancreas, have not been previously described. In a previous study, we determined that histologic lesions of the exocrine pancreas occurred much more frequently than gross lesions. The intention of the current study was to develop a histologic grading scheme for nonneoplastic lesions following...

e13607 Background: The Nottingham histologic grade (NHG) is a strong prognostic factor in early-stage breast cancer. It consists of nuclear pleomorphism, tubular formation, and mitotic count. We recently developed an artificial intelligence (AI) based automatic grading system. Methods: In this study, we have retrospectively evaluated 179,651 hematoxylin eosin-stained patches extracted from 402 ...
