Papilliferous Keratoameloblastoma: An Extremely Rare Case Report

Abstract

Odontogenic tumors develop in the jaw bones from the odontogenic tissue-oral epithelium in tooth germ, enamel organ, dental papilla, reduced enamel epithelium, remnants of Hertwig's root sheath or dental lamina, and so forth. Hence, a bewildering variety of tumors are encountered in the maxilla and mandible. Ameloblastoma is the second most common odontogenic neoplasm after odontomes, and it has numerous clinical and histologic variants. We report a very rare histologic variant: the papilliferous keratoameloblastoma which is the fifth reported case in the English literature.

Papilliferous Keratoameloblastoma

“…2 – 5 , 8 – 13 Half of the patients (n = 5, 50%) in these reported cases were of Indian origin. 2 , 5 , 11 – 13 The age of patients ranged from 18 to 76 years, with a mean age of 49.7 ± 20.95 years. In their review, Bedi et al .…”

Keratoameloblastoma: a case report and a review of the literature on its radiologic features

“…10 Papilliferous keratoameloblastoma and keratoameloblastoma were defined as separate entities in 1970 by Pindborg et al 2 The histological features of papilliferous keratoameloblastoma, characterized by papillary keratin lining, are different from those of keratoameloblastoma. 15 Therefore, in the current review, cases of papilliferous keratoameloblastoma were excluded.…”

Complex Composite Odontoma: A Cause of Impacted Teeth

“…Odontomas have also been associated with other odontogenic tumours like ameloblastoma [7] adenomatoid odontogenic tumour [8] and calcifying epithelial odontogenic tumour [9] and are then referred to as hybrid tumours. [10] Case Report: A 28-year-old female patient reported with missing upper molar on the right side. History revealed the second molar on the right maxillary arch did not erupt in childhood.…”
