Abstract
Infiltrating myoepithelial carcinoma remains an exceptional entity. Spindle cell morphology seems to be more prominent. However, rhabdoid, epithelioid and plasmacytoid morphologies may be seen. In some cases, this tumor may appear as poor differentiated intraductal carcinoma. Immunohistochemistry is very useful to confirm the diagnosis. Local recurrence and distant metastases are common but treatment is not consensual.We report a case of a 40-year-old woman with an unusual myoepithelial carcinoma. The diagnosis was canceled by the histopathological and immunohistochemical examination of the resected specimen.We discuss clinical and pathological features of myoepithelial carcinoma, which are very important to know by young pathologists.
