*  Ghost Cell Differentiation and Calcification in Ameloblastic Fibroma
Ghost cell differentiation within an ameloblastic fibroma is extremely rare. The ghost cells found in an ameloblastic fibroma in previously reported cases were all associated with a typical calcifying odontogenic cyst. Here, we report a case of an ameloblastic fibroma with focal ghost cells and calcifications in some neoplastic epithelial islands, but without other histologic manifestations consistent with a calcifying odontogenic cyst. The patient was a 13-year-old Chinese boy who presented with a bony-hard swelling in the posterior mandibular region over a 6-month period. Radiographs showed a well-defined multilocular radiolucency associated with an unerupted tooth. The lesion was mostly cystic-solid and comprised of odontogenic epithelial strands, islands and myxoid ectomesenchymal component microscopically. Small groups of ghost cells and calcification were noted in the epithelial islands ...

YANEZ M, RICARDO et al. Malignant mandibular ameloblastoma with hepatic and lung metastases: a case report. Rev Chil Cir [online]. 2009, vol.61, n.5, pp.458-462. ISSN 0718-4026. http://dx.doi.org/10.4067/S0718-40262009000500011.. Ameloblastoma is a benign rare tumor, originated in the odontogenic epithelium, is locally invasive and with high tendency to local recurrence, a variety less common is the malignant or metastasizing ameloblastoma, where more frequent sites of deployment are the lung and cervical lymph nodes, being much less frequent sites the liver and skull among others. The surgical treatment is mainly the aggressive surgery of the primary tumor and metastases. We present a case of a patient with malignant mandibular ameloblastoma with metastases in liver and lung, which was subjected to a subtotal mandibulectomy, local radiotherapy and lung and liver metastasectomy in a second time, with late recurrence of the lesion..

*  Soft Tissue Recurrence with a Mucocele of an Intraosseous Ameloblastoma » BLOG - Scientific Research Publishing
Ameloblastoma is an odontogenic tumor of high frequency and usually occurs as an intraosseous growth. Ameloblastomas frequently recur, sometimes undergoing malignant transformation. These tumors are usually characterized as being multilocular, of the follicular type histopathologically, and invading strongly at the border region of the tumor. More than 10% p53-positive tumor cells give a prognostic indication for a tendency to recur. A recurrent ameloblastoma usually occurs in the intraosseous region near the site of the original lesion. In very rare cases, a recurrent tumor proliferates distantly from the original site in the soft tissue only. We report a rare case of recurrent ameloblastoma in the buccal mucosa with a mucocele that originated from the small salivary glands after the extirpation of an intraosseous (mandibular) ameloblastoma. We also performed a p53 immunohistochemical study of this recurrent tumor.. ...
*  Neuroradiology On the Net: agosto 2010
Florid cemento-osseous dysplasia is a slow growing benign lesion which is extremely aggressive and infiltrative. It involves the periapical regions of both the maxilla and mandible with a diffuse distribution of mixed lucent-opaque osseous changes. The lesions are benign fibro-osseous lesions, which histologically, represent normal bone replaced by highly cellular fibrous connective tissue and cementum. Cemento-osseous dysplasia predominantly affects females greater than males (10-14:1) with a predilection for African American patients. Treatment of these lesions should be further radiographic follow-up without surgery unless the lesions become symptomatic, necrotic, or super-infected. Odontoma would also be in the differential as it is a hamartomatous malformation composed of odontogenic tissues. These lesions are usually discovered in the 2nd decade of life and can cause impaction, malpositioning or resorption of adjacent teeth. Ameloblastoma is the most common odontogenic tumor arising ...

Ameloblastic fibrosarcoma (AFS) is a rare malignant odontogenic neoplasm of the jaw. AFS is characteristically composed of a benign odontogenic epithelium and a malignant mesenchymal component. The posterior region of the mandible is the predominantly occupied site. In the present report, a new case of AFS in a 22-year-old male that originated from ameloblastic fibroma was described. Histologically, the tumor showed biphasic components: Benign epithelium and a malignant mesenchymal component. Immunochemical findings revealed that the tumor cells were positive for cluster of differentiation (CD) 34, vimentin, Ki-67 and p53, but negative for smooth muscle actin, S-100, CD68 and desmin ...
*  Maxillary ameloblastomas: a review of the literature and of a 15-year database. - Zurich Open Repository and Archive
INTRODUCTION: Cases of maxillary ameloblastomas from 15-year database (1986-2000) collected in the Department of Cranio-Maxillofacial Surgery of the University Hospital of Zurich were evaluated. PATIENTS: Twenty-six patients suffering from ameloblastoma had been collected. Five of them, had a maxillary ameloblastoma, three females and two males. METHODS: A clinical retrospective study was performed. In addition a review of the literature was undertaken and the findings have been compared and contrasted. PATIENTS: The overall incidence of ameloblastoma within the mandible (21) was four times higher than in the maxilla (5). In 69 per cent of the cases (18) it occurred in men, in 31 percent (8) in women. The sex ratio differed with the maxillary ameloblastomas: 40 percent male (2) and 60 per cent female (3). Although slow growing and nearly painless, it can reach a considerable size within the mid-face involving such highly specialized structures as the orbit, skull-base and brain. Wide ...
*  Ameloblastoma - Wikipedia
Ameloblastoma (from the early English word amel, meaning enamel + the Greek word blastos, meaning germ) is a rare, benign or cancerous tumor of odontogenic epithelium (ameloblasts, or outside portion, of the teeth during development) much more commonly appearing in the lower jaw than the upper jaw. It was recognized in 1827 by Cusack. This type of odontogenic neoplasm was designated as an adamantinoma in 1885 by the French physician Louis-Charles Malassez. It was finally renamed to the modern name ameloblastoma in 1930 by Ivey and Churchill. While these tumors are rarely malignant or metastatic (that is, they rarely spread to other parts of the body), and progress slowly, the resulting lesions can cause severe abnormalities of the face and jaw. Additionally, because abnormal cell growth easily infiltrates and destroys surrounding bony tissues, wide surgical excision is required to treat this disorder. If an aggressive tumor is left untreated, it can obstruct the nasal and oral airways making it ...
