Magnetic Resonance Imaging and Flexible Hysterofiberscopic Findings of a Uterine Adenofibroma: Case Report and Literature Review

Figure 4

Microscopic findings, showing that (a) the tumor resulted from the benign biphasic proliferation of epithelial and mesenchymal components. The epithelial elements were endometrial glands of benign appearance (HE stain, objective magnification ×20). The inset shows that the mesenchymal component consisted of endometrial stroma containing fibroblasts of benign nuclear features and very low mitotic activity (HE stain, objective magnification ×40): (b) the mesenchymal part was strongly positive on Masson’s trichrome staining, confirming the presence of collagen fibers (Masson’s trichrome stain, objective magnification ×10).
