case_images: A CT scan performed about 1 month after resection revealed an osteolytic lesion of 30 x 35 mm of the upper maxilla (Figure 2); MRI was not performed because the patient was claustrophobic.
case_images: (a) Hematoxylin eosin stain of the specimen (2x HPF). (b) Hematoxylin eosin stain of the specimen (10x HPF). (c) Immunohistochemistry showing positivity to a-smooth muscle actin (a-SMA) (2x HPF). (d) Immunohistochemistry showing positivity to a-smooth muscle actin (a-SMA) (10x HPF). ((e) and (f)) Immunohistochemistry revealing a mitotic index (Ki-67) of 90% positivity (2x HPF and 10x HPF).
