Tyrosine kinase 2 (TYK2) protein expression in malignant peripheral nerve sheath tumors (MPNSTs) and other sarcomas. TYK2 immunoreactivity was observed NF1‐associated and sporadic MPNSTs as well as other sarcomas. (A) Representative images of positive and negative staining for Plexiform Neurofibromas, NF1‐associated MPNSTs, sporadic MPNSTs, and Undifferentiated Pleomorphic Sarcoma (UPS), and fibrosarcoma. (B) Quantification of number of positive and negative cases observed for each type of tumor
