“…The occurrence of heterologous differentiation, as seen in our case, has been about 69% and mostly as cartilage, bone and skeletal muscle. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Such heterologous elements, usually cartilaginous, as seen in this case, may also be seen in adenofibroma, carcinosarcoma and embryonal rhabdomyosarcoma (ERMS). Like ERMS MAs may show cambium-like disposition but phyllodes-like histology seen in MA is not present in ERMS.…”
