Slide 1 (medium power, H&E). This field shows a moderately cellular lesion with a lightly staining myxoid background. The cells appear slender and contain deeply staining nuclei.
Slide 2 (high power, H&E). The cells contain deeply basophilic ovoid nuclei and exhibit slender elongated cytoplasmic extensions.
Diagnosis: Odontogenic Myxoma
