It is very important to be aware of the existence of these mimickers and to recognize their histological features. The differential diagnosis should be based on a comprehensive evaluation of clinical history, histological structure, cytological morphology and the results of immunohistochemistry （IHC） straining, rather than on single criteria （e.g., the presence of prominent nueleoli or basal cell layer）.展开更多
