Ameloblastic fibro-odontoma is a benign epithelial odontogenic tumor.
5) Deposition of hard tissue like dystrophic calcification or cartilage in the cyst wall of OKC is rare, and the presence of dentinlike tissue (Figure 2), even more rare, (7) can mimic other dentinoid-forming odontogenic cysts and tumors like calcifying epithelial odontogenic tumor, odontoma, ameloblastic fibro-odontoma and adenomatoid odontogenic tumor.
The present study is focused on the same, assessing the presence of stromal myofibroblasts in odontogenic tumors namely follicular ameloblastoma (FA), ameloblastic fibro-odontoma (AFO), adenomatoid odontogenic tumor (AOT), calcifying epithelial odontogenic tumor (CEOT) and odontogenic myxoma (OM), by expressing [alpha]SMA Immunohistochemically and correlate it to their aggressive biological behavior.
Lesions included adnexal neoplasm, ameloblastic fibro-odontoma, basal cell carcinoma, benign fibrous histiocytoma, blue nevus, chondrosarcoma, compound nevus, epithelioma adenoides cysticum, esthesioneuroblastoma, Ewing sarcoma, fibrosarcoma, giant cell granuloma, granulocytic sarcoma, hemangioma, hemangiopericytoma, Langerhans cell histiocytosis, lymphangioma, lymphoma, melanoma, neuroblastoma, neurofibroma, ossifying osteofibroma, osteochondroma, osteosarcoma, port wine stain, rhabdomyosarcoma, Spitz nevus, and xanthogranuloma.
The ameloblastic fibro-odontoma has the general features of an ameloblastic fibroma but also contains enamel and dentin.
In addition, less likely consideration included locally aggressive odontogenic lesions, such as ameloblastic fibro-odontoma, as well as other entities consisting of calcifying odontogenic cyst (Gorlin cyst), adenomatoid odontogenic tumor, and primordial cysts (keratocyst).
