MET immunohistochemical overexpression preferentially detected in myxofibrosarcomas of higher grades. Histological features of one each representative myxofibrosarcoma classified as FNCLCC grade 1 (a), grade 2 (b), and grade 3 (c). The grade 1 lesion showed no staining of MET (d), whereas overexpression of MET was readily found in grade 2 (e) and grade 3 (f) lesions.
