Recurrent ameloblastoma?--An historic case report and a review of the literature

Abstract

A case is described in which a patient who was originally treated by radical mandibular surgery including rib grafting, having been told that she had a dentigerous cyst, presented 49 years later with a follicular ameloblastoma. The case is discussed in an attempt to determine whether the initial diagnosis could have been ameloblastoma (if so, this demonstrates a long-term recurrence), whether this is a follicular ameloblastoma arising from remnants of an original dentigerous cyst, or whether this is an ameloblastoma, developing subsequently and coincidentally from adjacent dental lamina. This report is of historical interest, not only because of the long period of time that has elapsed between initial treatment and the present ameloblastoma, but also because of the eminent surgeons involved and the advanced techniques that they so proficiently carried out in 1942-1943.

Recurrent Ameloblastoma in the Free Fibula Flap: Review of Literature and an Unusual Case Report

“…Tumoral excision and mandibular reconstruction with bone graft is the preferred choice for recurrent cases by most maxillofacial surgeons. Some recurrences of ameloblastoma over bone grafts have been reported in the medical literature [22]. In these cases one should ask himself ''whether a more radical excision could have been done'' to prevent the recurrence.…”

“…The second factor is the anatomic localization of the tumor. The most common anatomic location for ameloblastoma is the mandible; which has a dense cortical bone structure that prevents spreading for several years [22]. The tumor can however extend beyond the radiological margin by spreading through the central cancellous bone [23].…”

Adenomatoid Ameloblastoma in the Mandible and Maxilla: Report of a Case

“…Clinically, it is painless and slow growing lesion, but behaves as invasive recurring tumours in spite of its benign histological appearance [1,2]. There are three different types of adenomatoid ameloblastoma: solid/multicystic, unicystic, and peripheral [7,8].…”

“…Ameloblastoma, a locally aggressive tumour of odontogenic origin, constitutes only 1% of all oral tumours [1][2][3][4][5][6]. Clinically, it is painless and slow growing lesion, but behaves as invasive recurring tumours in spite of its benign histological appearance [1,2].…”

Outcome of surgically resected mandibular ameloblastoma

“…3 Radiologically, it is a well-circumscribed unicystic or multicystic radiolucency and shows soap-bubble and honey-comb appearance. 4 Multicystic ameloblastoma can grow enormously sometimes and has a tendency to infiltrate into adjacent structures. It has the propensity to recur because numerous micro extensions projecting into the bone.…”
