Abstract
Pediatric odontogenic cysts and tumors are rare and often associated with developing or impacted teeth. Odontogenic cysts are broadly categorized as inflammatory or developmental while odontogenic tumors are classified histologically as epithelial, mesenchymal, or mixed tumors. This article will discuss the presentation, diagnosis, and treatment of odontogenic cysts and tumors in the pediatric population.

[PMID: 37046571 PMCID: PMC10093759 DOI: 10.3390/diagnostics13071353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2023] [Revised: 03/25/2023] [Accepted: 04/03/2023] [Indexed: 04/08/2023] Open
Abstract
Cancer is a problematic global health issue with an extremely high fatality rate throughout the world. The application of various machine learning techniques that have appeared in the field of cancer diagnosis in recent years has provided meaningful insights into efficient and precise treatment decision-making. Due to rapid advancements in sequencing technologies, the detection of cancer based on gene expression data has improved over the years. Different types of cancer affect different parts of the body in different ways. Cancer that affects the mouth, lip, and upper throat is known as oral cancer, which is the sixth most prevalent form of cancer worldwide. India, Bangladesh, China, the United States, and Pakistan are the top five countries with the highest rates of oral cavity disease and lip cancer. The major causes of oral cancer are excessive use of tobacco and cigarette smoking. Many people’s lives can be saved if oral cancer (OC) can be detected early. Early identification and diagnosis could assist doctors in providing better patient care and effective treatment. OC screening may advance with the implementation of artificial intelligence (AI) techniques. AI can provide assistance to the oncology sector by accurately analyzing a large dataset from several imaging modalities. This review deals with the implementation of AI during the early stages of cancer for the proper detection and treatment of OC. Furthermore, performance evaluations of several DL and ML models have been carried out to show that the DL model can overcome the difficult challenges associated with early cancerous lesions in the mouth. For this review, we have followed the rules recommended for the extension of scoping reviews and meta-analyses (PRISMA-ScR). Examining the reference lists for the chosen articles helped us gather more details on the subject. Additionally, we discussed AI’s drawbacks and its potential use in research on oral cancer. There are methods for reducing risk factors, such as reducing the use of tobacco and alcohol, as well as immunization against HPV infection to avoid oral cancer, or to lessen the burden of the disease. Additionally, officious methods for preventing oral diseases include training programs for doctors and patients as well as facilitating early diagnosis via screening high-risk populations for the disease.

Abstract
BACKGROUND Ameloblastic fibromas and ameloblastic fibrosarcomas are rare odontogenic tumors, and controversy exists in the classification of cases presenting hard-tissue production: Ameloblastic fibrodentinoma (AFD) and ameloblastic fibro-odontoma (AFO). These cases are currently considered “developing odontomas” (hamartomatous lesions).
AIM To analyze the clinicopathologic features of these lesions and discuss the changes in the 2017 World Health Organization classification.
METHODS An electronic literature search was performed in the PubMed/MEDLINE database. An electronic search of the English language literature was performed and last updated in September 2020 in the PubMed/MEDLINE database using the following terms: “ameloblastic fibroma”, “ameloblastic fibrodentinoma”, “ameloblastic fibro-odontoma”, “ameloblastic sarcoma”, “ameloblastic fibrosarcoma”, “ameloblastic fibrodentinosarcoma”, “ameloblastic fibroodontosarcoma” and “odontogenic carcinosarcoma”. The inclusion criteria were odontogenic tumor series, case reports and systematic reviews that provided sufficient clinical, radiological and microscopic documentation to confirm the diagnosis.
RESULTS The database search strategy resulted in 947 papers. Articles focusing on other topics, articles that were not in English, duplicate articles, and articles without fulfilling the inclusion criteria were excluded. Finally, 96 publications were included in this review to describe and discuss the main features of the searched entities. Several aspects of AFO and AFD, such as biological behavior, age of occurrence, amount of hard tissue, and potential for malignant transformation into odontogenic sarcomas, support the neoplastic nature in most of the reported cases. Considering the clinical, radiographic, histopathological and molecular characteristics of odontogenic lesions with hard tissue production, we suggest that these types of lesions should continue to be recognized as odontogenic tumors by maintaining the classically used terms.
CONCLUSION This recommendation will be relevant for future clinical, microscopic, and molecular studies to better understand the biology of these interesting odontogenic tumors.

Abstract
Ameloblastic fibrosarcoma (AFS) now designated as odontogenic sarcoma is a malignant odontogenic tumor characteristically composed of a benign epithelium and a malignant mesenchymal component. It can arise de novo without any preexisting lesion or it can result from the malignant transformation of ameloblastic fibroma (AF). Hereby, we report an extremely rare case of odontogenic sarcoma which was transformed from AF over a period of about 2 years. This is the first case to be reported after it has been reclassified as odontogenic sarcoma. A systematic review was also done to evaluate the studies that reported AFS arising de novo and AFS arising from AF. The objective of this study is to systematically review the studies that reported AFS arising de novo and AFS arising from AF. Articles that reported AFS arising de novo and AFS arising from AF were collected from PubMed, Medline, Embase, Cochrane, Google search and manual search. The results of the systematic review showed that six studies (46.1%) reported AFS arised de novo with no previous history of AF. Seven studies (53.84%) reported that amelobastic fibrosarcoma arised from AF. A rare case of odontogenic sarcoma transformed from AF is reported here. This is the first case report to be published on odontogenic sarcoma after the World Health Organization reclassification. AF once diagnosed should be treated immediately without any delay to avoid the chances of its malignant transformation into odontogenic sarcoma.

Abstract
Lack of dental eruption may be accompanied by development of dentigerous cysts and has also been rarely associated with neoplasia. However, little information is available on prevalence of unerupted teeth and associated lesions in dogs and cats. The main objective of this study was to describe the epidemiologic data of canine and feline dental patients with unerupted teeth, and assess the prevalence of associated dentigerous cysts and tumors. Secondary aims included the evaluation of possible factors implicated in cystic development, and description of the histological features of dentigerous cysts. Medical and dental records, intraoral photographs, intraoral radiographs of client-owned dogs and cats with clinically missing teeth examined between 2001 and March 2018 were reviewed. Collected data included signalment, reason for presentation, number, type, depth of inclusion and angulation of unerupted teeth, presence of cystic lesions or tumors, abnormalities affecting involved teeth, histopathological findings, performed treatment and outcome. Seventy-three animals (69 dogs and 4 cats) with 113 unerupted teeth were included. The most frequent unerupted tooth in dogs was the first premolar teeth (78%), followed by the canine and third molar teeth. Dentigerous cysts were diagnosed associated with 48 (44.4%) teeth in dogs and one out of five unerupted teeth in cats. The affected teeth in dogs were predominantly in horizontal inclination (40%) and in soft tissue inclusion (77%). Brachycephalic canine breeds were overrepresented. The only unerupted tooth in boxer dogs was the first premolar tooth (32 teeth). Ninety percentage of boxers with unerupted teeth developed associated lesions (25 dentigerous cysts and one tumor). Two ameloblastomas (one in a dog and one in a cat) and one osteosarcoma (in a dog) were diagnosed in association with three unerupted teeth. Histology was essential in diagnosing two odontogenic cysts not evident on radiographs. In all cases that were followed-up, treatment (i.e., extraction, extraction and surgical curettage, or operculectomy) appeared successful. Untreated dentigerous cysts showed progression at re-examination. None of the unerupted teeth without evidence of cyst at the time of diagnosis showed incipient cystic development. None of the evaluated factors were associated with lack of eruption and/or development of associated lesions.

Abstract
Ameloblastic fibrosarcoma (AFS) is a rare malignant odontogenic tumour classified by the WHO (1992) as an odontogenic sarcoma and defined as “a neoplasm with a similar structure to ameloblastic fibroma (AF) but in which the ectomesenchymal component shows the features of a sarcoma.” The first report of AFS was published by Heath in 1887. AFS and related lesions are less frequently diagnosed than odontogenic carcinomas. Approximately two-thirds of AFSs seem to arise de novo, but others have developed in recurrent AF, in which the ectomesenchymal cells retain their embryonic appearance and develop malignant characteristics. We report a rare case of an aggressive odontogenic neoplasm, the incisional biopsy of which showed the features of AF, while the excisional biopsy revealed the features of malignancy, suggestive of AFS. The purpose of this report is to discuss the diagnostic difficulties, whether AFS is truly an extremely rare tumour as reported earlier and, lastly, should the treatment protocols of AFs be revised, as 44% of AFSs arise from recurrent AFs.

Abstract
A data set has been developed for the reporting of excisional biopsies and resection specimens for malignant odontogenic tumors by members of an expert panel working on behalf of the International Collaboration on Cancer Reporting, an international organization established to unify and standardize reporting of cancers. Odontogenic tumors are rare, which limits evidence-based support for designing a scientifically sound data set for reporting them. Thus, the selection of reportable elements within the data set and considering them as either core or noncore is principally based on evidence from malignancies affecting other organ systems, limited case series, expert opinions, and/or anecdotal reports. Nevertheless, this data set serves as the initial step toward standardized reporting on malignant odontogenic tumors that should evolve over time as more evidence becomes available and functions as a prompt for further research to provide such evidence.

Abstract
Here is described a case of ameloblastic fibrosarcoma (AFS) affecting the posterior mandible of a woman who was treated surgically and recovered without signs of recurrence or metastasis after 12 years of follow-up. Tumor sections were immunostained for cell cycle, epithelial and mesenchymal markers. Immunohistochemical analysis evidenced high Ki-67 positivity in stromal cells (mean of 20.9 cells/High power field). Epithelial cells displayed strong positivity for p53, p63 and cytokeratin 19. In addition to the case report, a systematic review of current knowledge is presented on the AFS's clinical-demographic features and prognostic factors. Based on the review, 88/99 cases were diagnosed as AFS, 9/99 as ameloblastic fibro-odontosarcoma and 2/99 as ameloblastic fibrodentinosarcoma. All these lesions displayed very similar clinical-demographic and prognostic features. Moreover, the review provided evidence that first treatment, regional metastasis, distant metastasis and local recurrence were significant prognostic values for malignant odontogenic mesenchymal lesions. Based on the findings, segregation among ameloblastic fibrosarcoma, ameloblastic fibrodentinosarcoma and ameloblastic fibro-odontosarcoma seems illogical, considering all these lesions have similar predilections and outcomes.

Abstract
Ameloblastic fibro-odontosarcoma (AFOS) is an extremely rare malignant mixed odontogenic tumor. The ectomesenchymal part of the neoplasm shows malignancy, whereas the epithelial component is rather benign. In addition, small areas with deposition of enamel matrix and dentine material are seen. The rarity of this neoplasm and microscopic similarities with other malignant and benign tumors can lead to diagnostic problems. Here, we describe the histopathologic features of a new case of AFOS of the mandible in a 34-year-old female patient. It is essential for oral pathologists to be familiar with the microscopic features of this rare neoplasm to have a proper diagnosis. This is also the first reported case of AFOS that closely resembles osteosarcoma in some areas.

Abstract
INTRODUCTION Ameloblastic fibro-odontosarcoma is an extremely rare subtype of odontogenic sarcoma, with only 13 cases reported in the literature. CASE REPORT A 4-year-old male presented with a painless mandibular swelling, which appeared 4months previously. Cone beam computed tomography revealed an extensive, ill-circumscribed, multilocular radiolucency of the right mandible extending from the first deciduous molar to the ramus with slightly dense opacities. Histological examination of the incisional biopsy specimen revealed a biphasic tumor with sarcomatous mesenchyme and benign ameloblastic epithelial component compatible with a diagnosis of ameloblastic fibrosarcoma. A right hemimandibular resection was performed. Areas of deposition of dentinoid and enamel material closely adjacent to ameloblastic epithelium were noted in the excised specimen. A final diagnosis of ameloblastic fibro-odontosarcoma was made. After four years of close follow-up, there is no sign of recurrence or metastasis. CONCLUSION Although rare, ameloblastic fibro-odontosarcoma should be considered in the differential diagnosis of jaw lesions with radiographic radiolucencies exhibiting poorly circumscribed outlines and containing radiopaque material. Definite diagnosis depends on histopathological examination. Complete surgical excision is the treatment of choice.

Abstract
Objective Determine survival and factors affecting survival for patients with malignant tumors of odontogenic origin. Study Design Retrospective analysis of the National Cancer Institute’s SEER database (Surveillance, Epidemiology, and End Results). Setting Tertiary medical center. Subjects and Methods All cases of malignant tumors of odontogenic origin were extracted from the SEER database for the period of 1973 to 2011. Demographic, tumor-specific, and survival data were tabulated and Kaplan-Meier survival analysis conducted according to histopathologic results. Cox regression analysis stratified for histopathology was conducted to determine factors that influenced survival. Results A total of 308 cases of malignant tumors with odontogenic origin were analyzed. Malignant ameloblastoma accounted for 59.7% of cases, followed by malignant odontogenic tumor (35.4%; including odontogenic carcinoma, odontogenic sarcoma, primary intraosseous carcinoma, and ameloblastic carcinoma) and ameloblastic fibrosarcoma (2.9%). The overall mean and median were 229 and 227 months, respectively, while the 5-year survival rate was 81% for the entire cohort. Malignant ameloblastoma exhibited the best mean survival (237 months), whereas malignant odontogenic tumor (139 months) and ameloblastic fibrosarcoma (42 months) had lower mean survival rates. Younger age, surgery with adjuvant radiation, and smaller tumor size were found to improve survival. Conclusions Significantly different survival can be expected depending on individual tumor histopathology, tumor size, age at diagnosis, and treatment modality.

Abstract
BACKGROUND Odontogenic tumors such as ameloblastic fibro-odontoma (AFO) are rare conditions in children and are often asymptomatic. AFOs are found by routine clinical and radiological examination or when they cause obvious intra- or extra-oral swelling. MATERIALS AND METHODS A case of an AFO in a 7-year-old girl is described, and 107 cases from the literature and this report are analyzed. RESULTS The total of 108 cases revealed the average age at presentation of AFO to be 6.3 years in boys and 9.6 years in girls. There was a slight male predilection and AFO lesions most often occurred in the posterior mandible. AFO was almost always associated with an unerupted tooth or teeth. CONCLUSIONS While the recurrence rate of AFO was found to be 5.5%, long-term postoperative clinical and radiological follow-up is advised to ensure no future signs of aggressive recurrence.

Abstract
Ameloblastic fibro-odontosarcoma (AFOS) is an extremely rare malignant odontogenic tumor. Complete surgical excision is the treatment of choice. Deaths due to disease recurrence and/or progression are documented. Here, we report the case of a 15-year-old female with multiple recurrent AFOS. She responded to chemotherapy with ifosfamide and doxorubicin consolidated by stereotactic reirradiation using cyberknife and remained in complete remission 14 months from the end of reirradiation therapy. Chemotherapy with ifosfamide and doxorubicin should be considered in advanced cases of AFOS.

Abstract
Ameloblastic fibrosarcoma is an uncommon odontogenic tumor composed of a benign epithelial component and a malignant ectomesenchymal component most frequently seen in the third and fourth decades of life. It mainly presents as a painful maxillary or mandibular swelling. Radiographs show a radiolucent mass with ill-defined borders. Radical surgical excision and long-term follow-up are the suggested treatment. We report the case of a 22-year-old female with a 2-month history of an asymptomatic swelling in her left mandible. Examination revealed an exophytic growth measuring 3 × 3 cm extending from the mandibular left first premolar to the second molar. The patient underwent a left hemimandibular resection. Histopathological examination revealed a biphasic tumor composed of inconspicuous islands of benign odontogenic epithelium and an abundant malignant mesenchymal component with marked cellularity, nuclear pleomorphism, hyperchromatism, and moderate mitotic figures with clear margins; one year after the surgical procedure, the patient is clinically and radiologically disease-free.

Abstract
BACKGROUND Odontogenic tumours are a heterogeneous group of lesions formed from tissues that give rise to the tooth. DNA methylation, a covalent addition of a methyl group to the 5-carbon position of a cytosine nucleotide, is considered an important regulator of gene expression. The addition of the methyl radical is catalysed by DNA methyltransferases (DNMTs). Although some epigenetic studies have been conducted in odontogenic tumours, a study with the three types of DNMTs in several different members of this group is missing. This study analyses the expression of DNMTs in odontogenic tumours. METHODS Formalin-fixed and paraffin-embedded tissue samples of 20 ameloblastomas, 10 calcifying cystic odontogenic tumours, 10 calcifying epithelial tumours, 10 adenomatoid odontogenic tumours, 10 keratocystic odontogenic tumours, five ameloblastic fibromas, two ameloblastic fibro-odontomas, four central odontogenic fibromas, seven peripheral odontogenic fibromas and 10 odontogenic myxomas were included. Immunohistochemical expression of DNMT1, 3A and 3B was assessed using a semi-quantitative analysis, and also a correlation with p21, p27 and E-cadherin immunoexpression was made. RESULTS DNMT1, 3A and 3B were expressed in the nucleus and/or cytoplasm of all odontogenic tumours. DNMT1 expression was directly correlated with p27 expression in ameloblastomas. CONCLUSION The high expression of DNMTs in odontogenic tumour cells suggests methylation as an important mechanism for this group of tumours.

Abstract
Ameloblastic fibroma (AF) is a benign tumor of mixed odontogenic origin, which affects predominantly young individuals. AF appearing as a mixed radiographic image is very rare. This report describes a case of AF in a 12-year-old male identified during a routine radiographic exam for orthodontic treatment planning. The panoramic radiography revealed a well-defined multilocular mixed image located in the mandible between the roots of the left mandibular second premolar and first molar. The lesion was excised under local anesthesia. Histopathological analysis revealed islands of epithelial cells and columnar peripheral cells showing a nucleus in inverted polarization, interspersed with spindle-shaped cells and abundant extracellular matrix deposition. No atypia was observed. The diagnosis of AF was established. No tumor recurred up to 30 months after treatment. Although rare, AF should be also considered in the differential diagnosis of mixed radiographic images of the jaws in young patients.

Abstract
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. The clinical presentation, radiographic appearances and treatment measures were additionally described and reviewed.

Abstract
Ameloblastic fibrosarcoma (AFS) is a rare malignant mixed odontogenic tumor which is usually considered as the malignant counterpart of ameloblastic fibroma. Only mesenchymal component represents sarcomatous alterations and ameloblast-like epithelial nest remains bland in AFS. Here, we report a case of AFS in a 26-year-old man in the maxilla, which was regarded as an uncommon location for this tumor. After 2 years follow up, no evidence of recurrence was noted. We also emphasize on comprehensive clinical, radiographic, and histopathologic evaluation of such patients rather than immunohistochemical staining to make an accurate diagnosis.

Abstract
INTRODUCTION Ameloblastic fibrosarcoma (AFS) is a rare malignant odontogenic tumor. It can arise de novo, however one-third of cases may arise from a recurrent ameloblastic fibroma, in which case they appear to present at an older age. CASE REPORT A 16-year-old female presented with one month history of right mandibular mass. Computerized tomography (CT) scan showed a large destructive mass. A biopsy of the mass was performed. Histologically, it consisted of a mixed epithelial-mesenchymal odontogenic neoplasm composed of benign islands of well-differentiated ameloblastic epithelium within a malignant fibrous stroma consisting of spindle cells or fibroblasts with a brisk mitotic activity. The malignant spindle cell proliferation showed positive staining with p-53 and a high proliferation index with ki-67. A diagnosis of AFS was rendered. CONCLUSION The differential diagnosis includes other odontogenic sarcomas, ameloblastic carcinosarcoma and spindle cell carcinoma. Treatment of choice is wide surgical excision, with long-term follow-up. Postoperative chemotherapy and radiotherapy has been used successfully in a few reported cases. AFS is a locally aggressive malignant tumor, with regional and distant metastases being uncommon.

Abstract
OBJECTIVE The aim of this study was to show the epidemiological features of 25 malignant odontogenic tumors (MOT) in Latin America. MATERIALS AND METHODS We retrieved 25 cases of MOT out of 2142 odontogenic tumors, from four oral diagnostic centers in Latin America, and described the main clinical and pathological characteristics. RESULTS A total of 19 cases were carcinomas, including eight ameloblastic carcinomas, five primary intra-osseous squamous cell carcinomas, three clear cell odontogenic carcinomas and three ghost cell odontogenic carcinomas. All six sarcomas corresponded to ameloblastic fibrosarcoma. Thirteen cases occurred in men and 12 in women, age ranged from 7 to 77 years old, with a mean of 41.4 years. The average age of patients with carcinomas and sarcomas were 48.53 and 19 years old, respectively. CONCLUSION As malignant odontogenic tumors are very rare, this series helps to better clarify their relative frequency, predominant subtypes, and clinical characteristics in Latin America.

Abstract
Ameloblastic fibrosarcoma (AFS) is a rare malignant odontogenic tumor. We report 2 pediatric cases of AFS from 2 different centers but reviewed by the same pathologist, which were unusual in that they were chemosensitive. Management was wide surgical resection, chemotherapy, and adjuvant radiotherapy. One case was a local AFS recurrence after incomplete surgery and the other was an AFS that was overlooked during earlier diagnosis of an ameloblastic fibroma. Both tumors responded very well to preoperative chemotherapy, with a reduction in tumor size and histologically proven decrease in viable tumor cell number. Both patients are well after 13 and 14 months of follow-up.

Abstract
Ameloblastic fibrosarcoma or ameloblastic sarcoma is an extremely rare odontogenic neoplasm. We report a case of an ameloblastic fibrosarcoma arising from thyroid gland in a 44 year-old woman. Following total thyroidectomy, a histopathologic, immunohistologic, and genotypic examination revealed ameloblastic fibrosarcoma. The tumor was composed of odontogenic epithelium, resembling that of ameloblastoma, and a mesenchymal part exhibiting features of fibrosarcoma. To our review, our case represents the first report of ameloblastic fibrosarcoma of the thyroid gland. Ameloblastic fibrosarcoma may arise from thyroid gland.

Abstract
Ameloblastic fibrosarcoma is a malignant odontogenic tumor that rarely affects the skull base and surrounding regions. We present a case of a 48-year-old man with histologically confirmed malignant transformation of a benign ameloblastic fibroma 10 years after initial presentation of a localized facial mass. The ameloblastic fibrosarcoma extended from the facial region to the orbit, anterior and middle fossa skull base, the infratemporal fossa, and the cavernous sinus. Progressive proptosis with complete monocular vision loss was the presenting symptom. To our review, our case represents the first report of intradural extension of ameloblastic fibrosarcoma. Using a multidisciplinary skull base approach, resection of all tumors except that in the cavernous sinus was achieved with the resulting defect reconstructed with an anterolateral thigh free flap. The patient had no new neurologic deficits after surgery and underwent adjuvant fractionated radiation therapy. Malignant transformation of ameloblastic fibroma into ameloblastic fibrosarcoma can occur many years after initial presentation. Thus, vigilant long-term follow-up is essential despite the benign nature of the initial pathologic lesion. Use of a multidisciplinary approach is critical in obtaining the optimal outcome in these complex cases.

Abstract
Ameloblastic fibrosarcoma (AFS) is a rare malignant odontogenic tumour regarded as the malignant counterpart of ameloblastic fibroma. It is characterized by a benign epithelial component within a malignant fibrous stroma. AFS is a locally aggressive neoplasm with extremely low potential for metastasis. We report an extremely rare, rapidly progressive, and fatal case originating in the posterior mandible of a 20-year old female patient. Initially histopathologically diagnosed as a benign lesion, it rapidly recurred with apparent transformation into a high-grade sarcoma over a period of 6 months. Subsequent intracranial and pulmonary metastases were noted, and the patient died within 15 months of initial consultation. This case emphasizes the need for a high element of suspicion about clinically ambiguous lesions. We recommend more extensive or radical, primary excisions in lesions that have a known potential for recurrence or malignancy.

Abstract
This paper reports one case, of an ameloblastic fibro-odontosarcoma (AFOS) affecting the mandible, in a 12-year-old girl. This neoplasm is a rare odontogenic neoplasm. To the authors' knowledge this is the fifteenth case of AFOS reported in English. The patient's chief complaint was a swelling in the face for 6 months. An incisional biopsy was performed diagnosing the case as an ameloblastic fibroma. After radiography ameloblastic fibro-odontoma was diagnosed. Computed tomography was performed and a stereolithography model made to plan the surgical procedures. A hemimandibulectomy followed by a vascularized fibular flap was then proposed. The surgery was uneventful. Microscopic features diagnosed an AFOS. After 23 months of close follow-up there is no sign of recurrence or metastasis. Dental implants were recently placed in the fibular flap.

Abstract
Ameloblastic fibrosarcoma (AFS) or ameloblastic sarcoma is an extremely rare odontogenic neoplasm. The authors report AFS in the maxillary sinus of a 4-month-old boy. The tumor was composed of odontogenic epithelium, resembling that of ameloblastoma, and a mesenchymal part exhibiting features of fibrosarcoma. We also found some areas with deposition of dentinoid material closely adjacent to the ameloblastic epithelium. Although AFS has occurred in a wide age range, this is the first report of this tumor in infancy with long-term follow-up.

Abstract
A rare case of anaplastic ameloblastic fibrosarcoma (AS) arising in an ameloblastic fibroma (AF) of the maxilla of a 48-year-old patient 10 years after the primary excision is presented. The recurrent tumor retained focal areas of AF but manifested heterogeneous malignant features ranging from low-grade spindle to highly pleomorphic sarcomas. Biomarker analysis showed alterations of the p53 and c-KIT genes restricted to the sarcomatous component. The biological implications of these findings in the future management of these tumors are discussed.

Abstract
INTRODUCTION Ameloblastic fibrosarcoma is a rare malignant odontogenic tumour and is regarded as the malignant counterpart of the ameloblastic fibroma. The epithelial component remains benign, but the mesenchymal component becomes malignant. The diagnosis is made by histopathology. PATIENT The case of a 26-year-old man who underwent curettage of an ameloblastic fibroma and died of an ameloblastic fibrosarcoma is presented, and the course of malignant transformation is analysed retrospectively. CONCLUSION One-third of ameloblastic fibrosarcoma cases seem to have developed from recurrent ameloblastic fibromas. Knowledge of the malignant potential in the mesenchymal spindle cells of ameloblastic fibroma will assist in determining the management of these benign tumours, and may prevent malignant transformation to ameloblastic fibrosarcoma.

Abstract
Ameloblastic fibrosarcoma (AFS) is a rare malignant tumor of the jaw. The malignant mesenchymal component of AFS has been described as 'fibroblast-like', although little is known about the immunophenotype, except for vimentin expression. Here, we present a case of AFS in a 62-year-old woman. The mesenchymal component displayed the features of either dermatofibrosarcoma protuberans or fibrosarcoma, and was positive for CD34. This is the first reported case of CD34 expressing AFS in the maxilla.
