Plexiform ameloblastoma of mandible - case report

Abstract

Ameloblastoma, a benign epithelial odontogenic tumor, is locally aggressive. This tumor comprises about 1% of tumors and cysts arising in the jaws. It appears most commonly in the third to fifth decades and with equal frequency between sexes. Ameloblastoma prevalently occurs in the mandibular molar and the ramus areas. Recurrence frequently appears after inadequate treatment. They are usually benign in growth pattern but frequently invade locally and occasionally metastasize. In the present study, a case of unusually large plexiform ameloblastoma was presented with its clinical, radiological, histological features and treatment modalities, and this is the addition of one more case in the literature.

Ameloblastoma: an aggressive lesion of the mandible

“…Although ameloblastomas occur with equal frequency in both genders they are found slightly in higher frequency in women than men4 as seen in our case.…”

“…In the ameloblastoma of the mandible, the majority (70%) are located in the molar ramus region and 10–15% are found in association with an unerupted tooth 4. In the present case also ameloblastoma was found in the molar ramus region and was not associated with any unerupted tooth.…”

“…Ameloblastoma is a benign epithelial odontogenic tumour often aggressive and destructive with the capacity to erode bone and invade adjacent structures 4. Ameloblastoma of the lower jaw can progress to variable sizes (1–16 cm) and cause facial asymmetry, displacement of teeth, malocclusion and pathological fractures 1.…”

Acanthomatous ameloblastoma of mandible crossing the midline: A rare case report

“…[5,6] Acanthomatous ameloblastoma mostly occurs in older patients rather than younger ones. The mean age of occurrence (±standard deviation) was 61.3 ± 1.2 range 60-62 years with a peak incidence in the 7 th decade of life.…”

“…14, January-March, 2015 Annals of African Medicine the first detailed description of this lesion was by Falkson in 1879. [5,6] It is the most common odontogenic tumor although it represents only about 1% of tumors and cysts of the jaws and 11% of the odontogenic tumors. In the mandible (80% of ameloblastomas), 70% are located in the area of the molars or the ascending ramus, 20% in the premolar region and 10% in the anterior region.…”
