Figure 3.

Three distinct CD117-immunocytochemistry staining patterns ((a) to (c)) have been presented in the study. (a) is the staining pattern 1 (perimembrane or membrane associated) which is highly distributed in low-grade MCT. (b) depicts the staining pattern 2 (paranuclear) and (c) exhibits the staining pattern 3 (diffuse), respectively. These last two staining patterns are almost present in high-grade MCT (bar = 10 μm).
