Peripheral ameloblastoma is a rare tumor, which occurs in the soft tissue overlying alveolar bone.
We represent an unusual case of peripheral ameloblastoma arising in the right pterygomandibular space.
Case: The patient, a 66-year-old woman admitted to our hospital with complain of mass in the right retromandibular region. The tumor was excised under general anesthesia.
The postoperative course was uneventful with no sign of recurrence.
There has been some controversy concerning the relation between peripheral ameloblastoma and basal cell carcinoma.
By the identification of immunohistochemical localization of the human type IV collagen in this tumor, we could get some knowledges of this problem.
