Clinical characteristics and presentation of ameloblastomas: an 8-year retrospective study of 240 cases in Eastern Nigeria

Ameloblastoma: A clinical study of 25 Iraqi patients

“…[2] Historically it is believed that the tumor was described by Cusack in 1827 and detailed by Broca in 1868 and that Malassez was the first to coin the term adamantinoma to this tumor in 1885, and he suggested that it originates from the epithelial remnants of a developing root sheath, while the term ameloblastoma was introduced by Churchill in 1934. [3,[5][6][7] Clinically ameloblastoma accounts for about 1% of all cysts and tumors of the jaws and about 10%-58% of odontogenic tumors. [3,[5][6][7][8] The tumor affects all age groups but the peak incidence is in the third and the fourth decade of life, and mostly involving the mandibular molar ascending ramus region.…”

[3,[5][6][7][8] The tumor affects all age groups but the peak incidence is in the third and the fourth decade of life, and mostly involving the mandibular molar ascending ramus region. [2,9,10] Ameloblastoma can be divided into 3 main subtypes namely; Solid or Multicystic ameloblastoma (SA) which is the most common subtype, Cystic or Unicystic ameloblastoma (UA) which was first described in 1977 by Robinson and Martinez [11] and studied in detail and classified into luminal, intraluminal and mural types by Ackermann et al in 1988.…”

“…[15] Radiographically ameloblastoma appears as a radiolucent lesion of varying size either as a unilocular or multilocular, the latter is described as "soap bubble" appearance. [6,16] Surgical treatment includes conservative approaches involving enucleation and curettage which is associated with high recurrence rates or more radical treatment approaches such as marginal and segmental resection of the affected jaw bones. [1,5] Aims Geographic differences in clinical and pathological aspects of ameloblastoma have been suggested.…”

Acanthomatous Ameloblastoma

“…3,5,6 It has no sex predilection, has a wide age range, and appears as a lytic expansile lesion radiographically. 2,5,7 Depending on the appearance of the central reticulum, the terms spindle cell, granular, basal cell and acanthomatous are used. The term acanthomatous ameloblastoma is used when the central stellate reticulum displays squamous differentiation.…”

“…Ameloblastoma is a benign odontogenic tumor that comprises about 1% of all oral tumors and 9-11% of odontogenic tumors. [1][2][3][4] Over 80% occur in the mandible and 20% in the maxilla. 3,5,6 It has no sex predilection, has a wide age range, and appears as a lytic expansile lesion radiographically.…”
