Ameloblastomas are locally aggressive jaw tumors with a high propensity for recurrence that are believed to arise from remnants of odontogenic epithelium, lining of odontogenic cysts, and the basal layer of the overlying oral mucosa. The unusual presenting symptoms, as well as the highly destructive nature of these lesions when arising in the maxilla, make them worthy of consideration in the differential diagnosis of nasal and maxillary masses. We present a rare case of right maxillary ameloblastoma in a 48 year old male patient who presented with the main complaint of loosening of molar teeth. History also revealed unilateral nasal obstruction of long duration about which the patient was least concerned. The computed tomography scan revealed a soft tissue polypoidal mass in the right maxillary sinus involving alveolar arch of the maxilla, with expansion of sinus and erosion of posterolateral wall. Initial biopsy confirmed ameloblastoma, which was followed by excision of the tumor by radical surgery. The case represents an unusual presentation of a rare odontogenic tumor.
