None, Conflict of Interest: A previous study suggests that desmoplasia within the stromal connective tissue in DA represents a change that occurs during the maturation of xmeloblastoma ameloblastomas suggesting that the follicular component arises on a desmoplastic background in hybrid ameloblastoma lesions [ 16 ].

On palpation, the swelling was non-tender and the desoplastic findings were confirmed. Unlike with the conventional ameloblastomas, a strong positive reaction for collagen type VI has been observed in DA indicating active production of connective tissue within the stroma of DA [ 2 ].

Therefore, block excision is the most widely used treatment to avoid recurrence. In the immunoprofile, the tumor cells exhibit variable expression of S protein and desmin, similar to other types of solid multicystic a meloblastoma SMA.

Hybrid odontogenic tumors might result from the diverse differentiation potentials of odontogenic epithelial cells, whose multipotentiality is demonstrated by the number of different histopathological varieties of odontogenic tumors.
