Ameloblastoma is a benign but locally aggressive odontogenic tumor. Worldwide, maxillary ameloblastoma is rare, but its late detection renders adequate treatment difficult. Majority occur in the mandible with about 5-20% occurring in the maxillary bone. Here we report a case of plexiform ameloblastoma of the left maxilla in a 30-year-old male. The tumor was presented as a radiographically solid mass filling the left maxillary sinus and clinically as a maxillary swelling. The radio-pathological features of this tumor and the possibility of its sinonasal epithelium origin are discussed.
