case_images: The histopathological photomicrography of the tumor. A - Solid lesion composed by sheets of uniform cells. Small blood vessels are uniformly distributed within the tumor but may not be apparent (H&E, 2X); B - Solid glomus tumor showing monomorphic round cells with eosinophilic cytoplasm and central punched-out nuclei. (H&E, 40X).

case_images: No ulceration, nor vascular and/or perineural invasion (Figure 1A) was found. The vascular structures showed positivity with CD34. Therefore, the histopathology confirmed the diagnosis of glomus tumor of the stomach (Figure 1B).
case_images: Photomicrography of the tumor. A - Negative reaction for CD117 (40X); B - Positive reaction for actin (40X).

case_images: In the gastrointestinal tract, CD117 is a highly specific marker of gastrointestinal stromal tumors; it is not expressed by tumors in the differential diagnosis of a glomus tumor (Figure 2A). These glomus cells may show intense positivity for actin antibodies (Figure 2B).
