Non neoplastic lesions that may mimic epithelial malignancies of the endometrium: Morphological and immunohistochemical analysis

In this paper the author describes the morphological and immunohistochemical features of the most common benign epithelial lesions of the endometrium, which can be mistaken for neoplastic malignancies (pseudoneoplastic lesions). In addition, here it was demonstrated that both morphologic clinical data and immunohistochemical features are useful for an accurate differential pathological diagnosis from non-neoplastic lesions and epithelial malignancies.
