Photomicrograph showing the results of double-immunostaining of spindle cells. Positive reactivity for α-smooth muscle actin (SMA) is recognized as a blue immunohistochemical signal in the cytoplasm, and for myogenin is recognized as a red immunohistochemical signal in the nucleus. (A) Negative reactivity for both α-SMA and myogenin (× 1000). (B) Positive reactivity for α-SMA alone (× 1000). (C) Positive reactivity for myogenin alone (× 1000). (D) Positive reactivity for both α-SMA and myogenin (× 1000).
