Ameloblastic fibroma with ghost cell differentiation and calcification: A unique case report.

The ameloblastic fibroma (AF) is an uncommon odontogenic tumor that may present an aggressive behavior and may have potential for malignant transformation. Ghost cell differentiation within AF is extremely rare. There are only seven cases in English literature in which ghost cells are found in AF but all these previously reported cases were associated with typical calcifying odontogenic cyst. Here, we present a unique case in 3(1/2)-year-old child with solid lesion which comprised odontogenic epithelium strands, islands, and myxoid ectomesenchyme with focal areas of ghost cell differentiation and calcification associated with neoplastic epithelium.
