Atypical ductal hyperplasia Encapsulated papillary Adenomyoepithelial adenosis can be well circumscribed or consist of multiple foci of randomly arranged ductules with luminal secretion, similar to microglandular adenosis. +/- snouts. Microglandular adenosis can mimic breast carcinoma; attention to key features, including morphologic-immunophenotypic correlation, is essential in establishing the diagnosis. Occasional eosinophilic luminal secretions are noted.
