Epithelioid-cell Myofibroblastoma of the Breast: Expanding the Morphologic Spectrum
Magro G - This study emphasizes that epithelioid-cell MFB may be a diagnostic challenge, especially when evaluating needle core biopsies. Immunohistochemistry, revealing a variable coexpression of vimentin, desmin, (alpha)-smooth muscle actin, CD34, bcl-2 protein, CD99, CD10, estrogen/progesterone/androgen receptors, is crucial in confirming the diagnosis. Awareness of epithelioid-cell MFB is important to avoid a misdiagnosis of malignancy. [more...]
