Abstract
Ameloblastomas frequently occur in relatively young people, but are rarely seen in people aged 80 years or older. We report a case of mandibular ameloblastoma in an elderly patient with a review of the literature. The patient was a 82-year-old man who noticed swelling of the gingiva approximately 2 weeks prior to his initial visit. Computed tomography showed a radiolucent area with little radiopacity. Internal uniformity was observed at the site, with thinning of cortical bone which lacked continuity in some areas. The excision and curettage were performed under general anaesthesia. No recurrence has been observed 14 months after surgery.

Abstract
The present profile of the peripheral ameloblastoma (PA) is based on a literature survey of 160 published tumour cases. The PA is an exophytic growth localized to the soft tissues overlying the tooth-bearing areas of the jaws, the initial diagnosis often being fibrous epulis. In most cases there is no radiological evidence of bone involvement, but a superficial bone erosion--known as cupping or saucerization--may be detected at operation. The PA accounts for 2-10% of all ameloblastomas. The overall average age is 52.1 years, slightly higher for males (52.9 years) than for females (50.6 years). Thus, the PA occurs at a significantly higher age than the intraosseous ameloblastoma (IA; 37.4 years). The male/female ratio amounts to 1.9:1, as opposed to 1.2:1 for the IA. The male/female ratio for the Japanese cases included in this survey is 2.5:1 as opposed to that of non-Japanese cases 1.4:1. As to the location of PA, the maxilla/mandible ratio is 1:2.6. The mandibular premolar region accounts for 32.6% of all sites. Five extra-gingival lesions have been reported under the term PA. As these cases most likely represent salivary gland tumours, they are not accepted under the diagnosis of PA. The odontogenic gingival epithelial hamartoma shows clinical, histological and behavioural features almost identical to the PA, and it is discussed whether this lesion and the PA should be considered one and the same entity. Pathogenetically, two major sources are discussed: remnants of the dental lamina and the oral surface epithelium. Histologically, the PA consists of proliferating odontogenic epithelium exhibiting the same histomorphological cell types and patterns as seen in the IA. The stroma is that of a mature, fibrous connective tissue. The indolent biological behaviour dictates a conservative therapeutical approach. It is discussed whether PA is a true neoplastic counterpart of the IA or rather an odontogenic hamartomatous lesion. Six cases of malignant PA have been reported.

Abstract
Available literature on ameloblastoma of the jaw was reviewed, including publications from 1960 to 1993, and compared to the latest larger review, published by Small and Waldron in 1955. The average age of patients with ameloblastoma is 36 years. In developing countries ameloblastomas occur in younger patients. Men and women are equally affected. Women are 4 years younger than men when ameloblastomas first occur, and the tumours appear to be larger in females. Dominant clinical symptoms such as painless swelling and slow growth are non-characteristic. The ratio of ameloblastoma of the mandible to maxilla is 5 to 1. Ameloblastomas of the mandible occur 12 years earlier than those of the maxilla. Ameloblastomas occur most frequently in the molar region of the mandible. In Blacks, ameloblastomas occur more frequently in the anterior region of the jaws. Radiologically, 50% of ameloblastomas appear as multilocular radiolucent lesions with sharp delineation. Histologically, one-third are plexiform, one-third follicular; other variants such as acanthomatous ameloblastoma occur in older patients. Two percent of ameloblastomas are peripheral tumours. Unicystic ameloblastomas occurring in younger patients have been found in 6%. Detailed data on 345 patients with ameloblastoma were evaluated for clarification of therapeutic approaches. Chemotherapy and radiation seem to be contraindicated. Ameloblastomas of the maxilla should be treated as radically as possible, ameloblastomas of the mandible should also be treated radically. However, ameloblastomas which radiologically appear as unilocular lesions may be treated conservatively (enucleation, curettage), whenever all areas of the cystic lumen are controllable intraoperatively. Unicystic ameloblastomas occurring in patients 15 years younger than those with multisystic ameloblastoma may be treated conservatively except in cases with invasion of epithelium into the cyst wall. Different recurrence rates have been found for histological variants of the ameloblastoma. Follicular ameloblastomas appear to recur more often than the plexiform type. Unicystic ameloblastomas reveal lower recurrence rates than "non-unicystic" ameloblastomas. The peripheral type of ameloblastoma may be excised, since conservative therapy results in low recurrence rates. Postoperative follow-up is most important in the therapy of ameloblastoma, because more than 50% of all recurrences occur within 5 years postoperatively.

Abstract
A rare case of a multicentric peripheral ameloblastoma of the gingiva in a 54-year-old male patient is described along with a light and electron microscopic study of the excised tumors. The peripheral ameloblastoma is considered to be the gingival counterpart of the more common intraosseous ameloblastoma. Although both tumors have similar histomorphologic characteristics, their clinical appearance and behavior are completely different. The peripheral ameloblastoma is slow growing and non-invasive, and recurrence is uncommon following excision. The more common central ameloblastoma, is locally invasive and can destroy large segments of the jaw. The histogenesis of the peripheral ameloblastoma and several other odontogenic tumors of the gingiva serves to illustrate the proliferative potential of the basal cell layer of gingival epithelium.

Abstract
Peripheral ameloblastoma is a benign odontogenic tumor with the same histological characteristics as the centrally located ameloblastoma, but appearing in the gingiva and mucosa of the tooth-bearing area of the jaws. A review is presented of 53 cases: 45 being reported as peripheral ameloblastoma and 8 as basal cell carcinoma of the gingiva, including the case presented. Based on the review it is recommended to treat this lesion by local excision including a small margin of healthy tissue. Local recurrence is unlikely, unless incomplete removal is performed.

Abstract
A case of peripheral ameloblastoma, a rare intraoral neoplasm, has been presented. The lesion appears most commonly as a mass on the mandibular lingual gingiva of patients in their fifth and sixth decades of life. The peripheral ameloblastoma does not share the aggressive nature of the intraosseous variant. The lesion has been overtreated in the past and warrants only a local supraperiosteal excision.

Abstract
Reports of gingival peripheral ameloblastoma are extremely rare and have been sporadic. This paper reports a pertinent case of a 40-year-old woman who for 2 years had a progressively enlarging asymptomatic firm mass in the buccal gingival region of the lower premolars. Cupping of the underlying bone was radiographically demonstrated. The lesion was excised surgically together with extraction of the first premolar, and no evidence of recurrence was seen 5 years later. The clinical, radiological, and histopathological characteristics of gingival peripheral ameloblastoma were analyzed in the 33 previously reported cases. The differential diagnosis and treatment of this case report are discussed.

Abstract
Peripheral (extraosseous or soft tissue) odontogenic tumors are rare lesions that occur in the soft tissue overlying the tooth-bearing areas of the mandible and the maxilla. A review of the English-language literature revealed only 48 well-documented cases of peripheral epithelial odontogenic tumors. Thirty-two were peripheral ameloblastomas; six were peripheral adenomatoid odontogenic tumors; nine were peripheral calcifying epithelial odontogenic tumors; and one was a peripheral squamous odontogenic tumor. An additional four cases were reported as peripheral ameloblastomas in extragingival locations, but their odontogenic origin is debatable. Although the peripheral ameloblastoma is histologically similar to its central counterpart, it differs in its clinical features and biologic behavior. It does not exhibit an aggressive, destructive behavior and does not invade the underlying bone. Conservative excision of the tumor with minimal but adequate margins is the treatment of choice and recurrences are uncommon. This benign biologic behavior appears to be true also for lesions diagnosed as peripheral calcifying epithelial odontogenic tumors and undoubtedly is true for the peripheral adenomatoid odontogenic tumors.

Abstract
The peripheral or extraosseous ameloblastoma is a rare tumour of the oral cavity. Only a few well-documented cases have been reported. One additional case of this infrequent tumour in a 70-year-old edentulous man is described. The tumour arose on the mucosa of the lower alveolar crest. It was asymptomatic tender, with a raised and red appearance. The tumour was excised and no evidence of recurrence was seen five years later. Peripheral ameloblastoma probably arises from oral mucosa or from cell rests. It is less invasive than its intraosseous counterpart, and surgical excision with adequate margins is the treatment of choice.
