Ghost cell differentiation within an ameloblastic fibroma is extremely rare. The ghost cells found in an ameloblastic fibroma in previously reported cases were all associated with a typical calcifying odontogenic cyst. Here, we report a case of an ameloblastic fibroma with focal ghost cells and calcifications in some neoplastic epithelial islands, but without other histologic manifestations consistent with a calcifying odontogenic cyst. The patient was a 13-year-old Chinese boy who presented with a bony-hard swelling in the posterior mandibular region over a 6-month period. Radiographs showed a well-defined multilocular radiolucency associated with an unerupted tooth. The lesion was mostly cystic-solid and comprised of odontogenic epithelial strands, islands and myxoid ectomesenchymal component microscopically. Small groups of ghost cells and calcification were noted in the epithelial islands.
