Objectives: To describe cytology patterns in low-grade @entity1962 (LGASCs) of the breast. Study Design: Low-grade @entity1962 of the breast are a recently described rare variant of primary @entity189 characterized by clinical indolence, slow evolution and excellent survival. To date, only 7 cases of LGASC were studied cytologically, and it was demonstrated that LGASC identification was difficult because its cellular components exhibited unspecific and nonsuspicious features. They consisted of irregularly clustered cells without prominent cytonuclear atypia, @entity4498 or @entity39 . The presence of metaplastic cells or keratin debris was helpful in accurate @entity5 typing. We report here 3 additional cases of LGASC that were initially studied by fine-needle aspiration. Results: We have also encountered diagnostic difficulties and misdiagnosed @entity5 , since 2 cases were underdiagnosed as 'suspicious' and only 1 was accurately diagnosed as @entity5 . Conclusion: The review of our cases and the literature confirms that, despite its putative metaplastic origin, LGASC is an entity which is difficult to diagnose using classical cytological methods. Moreover, core-needle biopsy as well as frozen sections may also misdiagnose LGASC as a benign breast lesion.    2014 S. Karger AG, Basel.
