This paper reports a basal cell ameloblastoma affecting a 66-year-old man whose chief complaint was swelling of the left maxillogingival region.<BR>Buccal cavity examination showed an edentulous jaw with an elastic soft bulge and a tiny round ulcer in the left maxillary tubercle. X-ray examination indicated comparatively clear-cut bone resorption in the left maxillary tubercle. Exploratory excision resulted in a histopathological diagnosis of ameloblastoma, which prompted us to perform left partial maxillectomy. One year and 7 months after the operation, relapse occurred across the pterygoplatine fossa towards the proper nasal cavity. Under these conditions, maxillectomy was reperformed.<BR>Histopathological examination of the removed portion of the maxilla showed the presence cells which principally resembled basal cells. These basal-like cells were partly continuous with the mucous epithelium and became increasingly diffuse with increasing depth.
