A Peripheral Ameloblastic Fibro-Odontoma in a 3-Year-Old Girl: Case Report, Immunohistochemical Analysis, and Literature Review
Immunohistochemistry for amelogenin, β-catenin, CD31, and CD44. The stainings showed that amelogenin, β-catenin, and CD44 were strongly expressed in the enamel epithelial cells. Some of the stromal cells, leukocytes, and endothelial cells were also positive for CD44 staining. CD31 staining appeared in the endothelial cells of the tumor stroma, especially in the area adjacent to the enamel epithelium. Scale bar = 100 μm for all panels but the bottom right (25 μm).
