“…It is an aggressive neoplasm that arises from remnants of the dental lamina and dental organ (odontogenic epithelium) (3). Most ameloblastomas develop in the molar-ramus region of the mandible with 70% of these arising in the molar-ramus area and they are occasionally associated with unerupted third molar teeth (4). Ameloblastoma appears most commonly in the third to fifth decades but the lesion can be found in any age group including children (2,5).…”

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.

RESUMENSe presenta una paciente de sexo femenino con diagnóstico de ameloblastoma folicular que se comportó de manera extraordinariamente agresiva, considerando este tipo histológico, con recidiva extensa que requirió cirugía radical y reconstrucción con doble colgajo libre, y que a pesar de obtener márgenes negativos, presenta una nueva y más extensa recidiva, quedando fuera del alcance quirúrgico y falleciendo 11 meses luego de la última cirugía.PALABRAS CLAVE: Ameloblastoma, tumores odontogénicos. ABSTRACTWe report a female consulting for a lump in the posteroinferior portion of the mouth with a foul smelling discharge. A partial jaw excision is performed and pathology reported a follicular ameloblastoma. A postoperative CAT scan showed a mass in the operated jaw angle. The patient was lost from control and returned three years later with a large mass. A radical excision was performed. There was a tumor relapse and the patient died 11 months after the last surgery.

“…They occur in three different clinicoradiographic situations which deserve separate consideration because of differing therapeutic considerations and prognosis [1,[5][6][7]. These are: conventional solid or multicystic (about 86% of all cases); unicystic (about 13% of all cases); and peripheral (extraosseous; about 1% of all cases) [1,2,9,10]. It is well known that ameloblastoma can be radiologically unilocular or multilocular and that unilocular or multilocular ameloblastoma may be histologically unicystic or multicystic [10].…”

The purpose of this case report is to compare the clinical and histopathologic features of granular cell ameloblastoma with critical review on literature. Data with respect to the histologic types regarding tumor with higher recurrence rates are also investigated. Numerous cases of ameloblastoma have been reported in the literature. However, only a few articles discuss granular cell ameloblastoma and few closely examine their nature and pathogenesis. In this case report, we analyzed the clinical and histopathologic features of granular cell ameloblastoma. a very coarse, granular eosinophilic appearance. Granular cell variety of ameloblastoma appears to be an aggressive lesion with a marked proclivity for recurrence. In addition, several cases of this type have been reported as metastasizing. The lesion have been shown to recur, particularly following inadequate surgical treatment [10]. Case ReportA female patient aged 34 yrs complains of swelling of left side gingiva in the region of canine and premolar since 1 yr. Which was smaller in size and gradually grown to present size, with difficulty in chewing as the growth is interfering in occlusion. On examination the sessile growth originated from left side of gingiva both lingually and buccally in relation to premolars. Which was approximately of 3×4 cm in size and superiorly above the occlusal plane and inferiorly the buccal vestibule. The lesion extends anteriorly from canine and posteriorly till mesial aspect of first molar. It was non tender and no lymphadenopathy felt. After routine blood investigations the patient posted for excisional biopsy. Under general anesthesia peripheral osteotomy performed and specimen sent for histopathology diagnosis.Histopathological report of excisional biopsy taken from right buccal vestibule in relation to 45 & 46 region revealed islands of ameloblastic epithelium in a fibrous connective tissue stroma. The centre of the island shows granular cells with eosinophilic granular cytoplasm and central nucleus. These features are suggestive of granular cell variant of ameloblastoma. DiscussionThe granular cell ameloblastoma is characterized by the presence of large masses of granular cells located within the follicles ( Figure 1). This occurs in 1% -5% of cases [15,16]. The cells are large, round, or polyhedral, and densely packed with eosinophilic granules and frequently demonstrate well-defined borders but, in some instances, form a syncytium. The nuclei are generally pyknotic and eccentrically displaced (Figures 2 and 3). The cells replace all or part of the stellate reticulum and, quite often the peripheral cells as well [15,17]. The granular cells are periodic acid-Schiff-positive and diastase resistant [18]. In our case much similar histopathologic finding of granular cell variant seen clearly.
