Figure 3
Immunoreactivity of metaplastic carcinoma. (a) Strong immunoreactivity for vimentin in the sarcomatous component. (b) Immunoreactivity for cytokeratin AE1/AE3 is present in few cells of the sarcomatous component. (c) Reactivity for smooth muscle actin in focal area. (d) Immunoreactivity for CD68 in osteoclast-like cells. (e) Nuclear immunoreactivity for Ki-67. (f) Expression of p53 (polymer-HRP detection system, biotin-free).
