Ameloblastoma arising within a globulomaxillary cyst

Unsuspected small ameloblastoma in the alveolar bone: a collaborative study of 14 cases with discussion of their cellular sources

“…Unsuspected small IA in the alveolar region have been well recognized for many years (1, 11, 15–23), with at least 60 well‐documented cases in the English and Japanese literature [(2, 11, 24–46); see Refs (3, 47, 48) for an additional list of references]. Twelve lesions have been reported as peripheral counterparts (2, 28, 32), but it is eminently clear that they are a superficially located IA which penetrated through the alveolar bone cortex into the gingiva (47, 48).…”

“…Twelve lesions have been reported as peripheral counterparts (2, 28, 32), but it is eminently clear that they are a superficially located IA which penetrated through the alveolar bone cortex into the gingiva (47, 48). There were 33 interradicular (2, 11, 24–36), nine residual (2, 37–39), seven periapical (40–42), five paradental (43–45), four pericoronal (2), and two periradicular (46) types. Two reports of interradicular IA from Japan have more than a passing interest.…”

“…Although no example in this series, IA of paradental setting that primarily affected the mandibular retromolar alveolar ridge may arise from a distal extension of accessional dental lamina (1, 15, 43–45). With regard to the origin of residual form of IA, much debate stems (2, 15, 18, 37–39). Of note is that in five patients (37–39; cases 13 and 14), related teeth had been removed many years previously, prior to the onset of IA.…”

Globulomaxillary cyst: does it still exist? A case report

“…There is a case report presenting a panoramic radiograph which revealed a unique solitary, well-defined, round, unilocular radiolucency with corticated border overlying the displaced roots of 22 and 23 ( Figure 5) 16 . Aisenberg and Inman announced a very rare case of ameloblastoma arising from the epithelium of a nonodontogenic globulomaxillary cyst 17 . Robinson et al noted in a GBC both stratified, squamous, and ciliated columnar epithelium, with clinical, radiographic, and microscopic evidences compatible with a diagnosis of an infected GBC 18 .…”
