Figure 6. (A) Microscopic image of the gastrointestinal stromal tumor (GIST). The tumor is composed of subepithelial interlacing spindle cell proliferation. Genetic testing of the tumor confirmed a PDGFRA gene alteration with wild-type KIT. (B) Higher-magnification microscopic image of the low-grade (G1) GIST. The tumor is composed of interlacing, essentially spindle cell proliferation with dilated vessels. No necrosis is evident. The tumor has 1 mitosis per 50 high-power fields, and thus, very low risk/low malignant potential. (C) Microscopic image of immunostaining of the GIST. The strong positivity for DOG-1 underscores the mesenchymal origin of the tumor.
