1) Finally, immunoreactivity for smooth muscle actin and desmin and negativity for CD117 and CD 34 ruled out GISTs.
Right: A strong desmin reaction is seen in the cytoplasm of the primitive cells.
They are stained positively for vimentin, desmin and SMA (5).

Schwannomas are S100 positive, GIST are CD 117 and DOG1 positive, leiomyoma and leiomyasarcoma shows positivity for Smooth muscle actin and desmin.
Staining for desmin is less reliable because it is positive in about two -thirds of cases.
A), myogenin (B), and desmin (C) are expressed relative to [beta]-actin expression.
Strong and diffuse expression of CD117 is very limited in soft tissue sarcomas other than GISTs; 30-40% of cases are positive for CD34 and SMA, while very few are reactive for desmin and S-100 (13).
It is sometimes stained positively for CD34; however, its infiltrative growth pattern, fibromatosis-like histology, and strong staining for desmin and muscle actins allow differential diagnosis.
1,2) Typically, the lesional cells of MFB are immuno-reactive for muscle markers, including desmin and smooth muscle actin due to their myofibroblastic origin.
Desmin is rarely expressed, and S-100 and CK are negative, different from neural and epithelial lesions.
On immunohistochemistry, the neoplastic cells of leiomyomas are characterized by SMA and desmin positivity (Figure 4, A and B) and are negative for S100, CD117, DOG-1, bcl-2, [beta]-catenin, and ALK.
