“…Historically, glandular and pseudoglandular (adenoid) features have been described as being part of the histologic spectrum of AME. 67,68 However, these early reports do not comment on the clinical, behavioral, and therapeutic significance of identifying the glandular and pseudoglandular elements within AME.

“…[20][21][22][23][24][25][26][27][28][29][30] The presence of glandlike structures within AME has, in the past, been referred to as "pseudoglandular AME" or "adenoameloblastoma." 67,68 It is conceivable that AAD is at the extreme end of the spectrum of behavior of AME in relation to local infiltration and recurrence and where pseudoglandular differentiation and dentinoid maybe a prominent feature. At present, data and characterization of AAD are insufficient, and this warrants its recognition as a separate entity from AME.…”

Two cases of melanotic neuroectodermal tumor of infancy were examined by electron microscopy and an extensive review of the literature was performed. Ultrastructural examination revealed several features not previously described for this lesion. Three different types of melanin granule formation were observed, many cells had a single cilium, and cell junctions of the "close" or "modified-tight" type were seen, but no desmosomes were found. The morphologic data were consistent with the concept that the tumor arises from neural crest cells. The review of the literature indicated that there have been 158 reported cases of this lesion, including the two reported here. There were five cases of malignant tumor reported for a rate of 3.2%. This rate of malignancy is very high in view of the fact that the tumor has been described as universally benign. The significance of this finding is discussed with regard to melanin-producing lesions of the oral cavity.

“…[14][15][16][17][18] Squamous epithelium of the oral mucosa is thought to have the potential to differentiate into ameloblastic cells. 1,15,17,18 Some of the peripheral ameloblastoma show continuity with the surface epithelium and elongation of basal or parabasal cells of the squamous epithelium.…”

Peripheral ameloblastic carcinoma is an extremely rare odontogenic tumor derived from the remnants of dental lamina and/or mucosal epithelium of the oral mucosa. We present a case of secondary peripheral ameloblastic carcinoma of the mandibular gingiva. The patient was a 71-year-old man with gingival swelling and persistent bleeding. Exfoliative cytology revealed cohesive clusters composed of basaloid cells with nuclear atypia and various forms of keratinized cells of dysplastic squamous appearance. Some cell groups had a peripheral palisade. Histology of the biopsy and surgically removed specimens revealed characteristic features resembling squamous cell carcinoma, basal cell carcinoma, and benign follicles of ameloblastoma. These neoplastic structures, as well as proliferation and elongation of the mucosal epithelium, comprised an extensive network. The varied cytopathologic findings may be related to proliferation and transformation of basal cells of the mucosal epithelium toward ameloblastic carcinoma and variable squamous differentiation.
