UNASSIGNED: @entity20372 of breast are rare @entity5 . We report for the first time a case of an @entity0 . A 53-year-old @entity1 had an annual screening mammogram, which identified areas of asymmetry in her left breast at 4-5-o'clock position. Resection of the masses revealed a well-circumscribed, gray-white, firm discrete nodule (0.8 * 0.4 * 0.3 cm). The @entity5 was composed of both @entity1373 and focal @entity1137 . The 2 cell populations had some overlapping histologic features. Immunohistochemical analysis demonstrated a biphasic proliferation with approximately equal parts of luminal epithelial cells with clear and rounded appearance and myoepithelial cells. The myoepithelial component of the proliferation expressed @entity3999 , @entity4206 , @entity4205 , S-100, and dimly expressed @entity5962 . The epithelial component of the proliferation strongly expressed @entity5962 . In the areas of @entity1137 , there was distinct loss @entity5962 expression. Awareness of this association is highly important to provide these @entity1 adequate follow-up and treatment.
