ABSTRACT Aim To report a small intaalveolar ameloblastoma which resembled cystic lesion, and to emphasize the value of Computed tomography (CT) in radiographic examination. Background Ameloblastoma is a slow-growing, locally invasive odontogenic neoplasm that accounts for approximately 10% of all tumors detected in the jaws. Radiographically, those tumors are usually well-defined. Computerized tomography is highly recommended to confirm the diagnosis. Case description A 48-year-old female attended with a chief complaint of painless swelling in the left anterior of mandible, 1 month duration. In intraoral examination, non-fluctuant, immobile, approximately 1 × 1 cm in dimension, painless, swelling which had a bone-like hardness and located in the mandibular canine region was detected. Panoramic radiography revealed a well circumscribed unilocular radiolucent lesion located in the inter-radicular area of left mandibular lateral and canine teeth. In CT examination it was realized that the lesion was multilocular. Histopathological examination of the biopsy specimen was reported as ameloblastoma. Clinical significance It is extremely difficult to find such an ameloblastoma in small dimension in alvolar bone. How to cite this article Canger EM, Çelenk P, Bulut E, Günhan Ö.

Ameloblastoma is the only odontogenic tumor that displays diversified histomorphological features with subtypes like follicular, plexiform, acanthomatous, granular cell, clear cell, desmoplastic etc. In this paper we presented an extremely unusual presentation of ameloblastoma, which is characterized by desmolysis or acantholysis of stellate reticulum-like cells caused due to keratinocyte dissociation. A 35-year-old male patient presented with a painless hard 3cm x 3cm swelling in the mandibular right posterior region since 4-5 months. Radiographic examination reveled a multi-locular radiolucent lesion in the body of mandible with resorption of the roots. Histopathological examination revealed ameloblastic follicles with central cells showing keratinocyte dissociation leading to desmolysis/acantholysis. Desmolytic cells were seen as an isolated entity in the follicular space with round to polygonal shaped morphology. Future retrospective studies on archival samples of ameloblastoma are recommended to relook into identification of such rare phenomenon. This will help in better understanding of the incidence rate and biological behavior of this rare variant of ameloblastoma.

Stafne Bone Defect

SummaryBackround/Aim: Stafne bone cavity which is also known as lingual mandibular bone defect is generally seen in the posterior region of the mandible. Stafne bone defects of the anterior mandible are very rare, with around 50 cases reported in the English literature. They are generally asymptomatic and incidental lesion findings may be diagnosed during a radiographic examination.Case Report: A 59 year-old female patient was examined for dental complaints. Panoramic radiography revealed a unilocular lesion at the left incisor- premolar area. Dental volumetric tomography scans showed a concavity at the lingual side of the related area. Magnetic resonance imaging was suggested for possible soft tissue pathology and, depending on MRI finding, the cavity was initially diagnosed as Stafne bone defect.Conclusion: The aim of this case report is to describe an unusually located Stafne bone cavity with special emphasis to the need of using special imaging modalities.

Introduction. We report a rare case of unicystic ameloblastoma (UA) of mandible which showed multilocular radiolucency on the left side of mandible on radiographic examination which is very unusual, and the majority of the cases of UAs till date has been reported of unilocular radiolucency. On histopathological examination, an odontogenic cystic lining that proliferates that intraluminally resembling ameloblastomatous epithelium was observed, leading to a definitive diagnosis of unicystic ameloblastoma.Case Presentation. A 42-year-old male patient presented with a swelling on the left side of the mandible extending from 33 to 36. Radiographically, it showed a multilocular radiolucent lesion resembling odontogenic cyst; however, the final diagnosis was made on histopathological ground with the inclusion of radiological and clinical features.Conclusion. It can be concluded that at present, histopathologic examination is the most sensitive tool for differentiating between odontogenic cysts and UAs. However, both clinical and radiologic findings share equal contribution to the final diagnosis.

The article describes an unusual case of an apical lesion at the first premolar with spontaneous pain and swelling around the root and tooth mobility at the maxillary right central and lateral incisors. The patient was a 45-year-old man with a chief complaint of discomfort at the maxillary right central and lateral incisors for one year. Oral examination showed spontaneous pain, swelling, and tooth mobility of the maxillary right central and lateral incisors. Intraoral and panoramic radiographs showed clear apical radiolucency at these sites, although there were no carious incisors. Neither tooth had periodontal pockets, and there was no bleeding on probing sites. A cold thermal examination revealed normal responses of the vital dental pulp. Initial panoramic radiography showed an apical lesion of the maxillary right first premolar, which was root filled and without inflammatory symptoms. A cone beam computed tomography (CBCT) revealed that the apical lesion of the premolar had extensively spread to the anterior through the palatal side, circumventing the palatal side of the adjacent canine, and reached the apical areas of the central and lateral incisors. We treated the apical lesion of the first premolar, and the radiolucent regions had almost disappeared after three years with regard to not only the apical lesion in the first premolar and incisors but also the primary symptoms on the incisors without endodontic treatment. This case shows that CBCT is an effective alternative that allows appropriate treatment to be selected more reliably.

Introduction. Osteomas are a slow growing benign neoplasm of unknown etiology very rarely involving the temporal bone. They develop in the external auditory canal on squamous sections, in the mastoid, middle and inner ear. By bone composition they are divided into spongious (osteoma spongiosum) and compact osteomas (osteoma eburnum); by growth direction, into outward-growing (exosteoma) and in inwardgrowing (endosteoma); into unilateral and bilateral; by size, into small and gigantic; by surface structure, into smooth and multilobular; by number, into solitary and multiple; into symmetrical and asymmetrical. The symptoms of intracanalicular osteomas are the result of auditory canal obstruction. Diagnosis is made based on case history, clinical examination, audiological processing and radiography (temporal bone CT scan), and confirmed by histopathological examination of the bone. In terms of differential diagnosis, they must be distinguished from exostoses, bone tissue proliferation and osteoid osteomata. The progress of the disease is prolonged, as they are slow growing, asymptomatic and benign tumours. Therapy is surgical only. Case Outline. The report presents the case of a 70-year old patient with the osteoma of the right external auditory canal. In our patient, the osteoma arose in the auditory canal, the most frequent localization; it was unilateral, solitary, multilobular and compact. It was discovered accidentally, during otoscopic examination. The clinical diagnosis was confirmed by CT scan of the temporal bone. We applied surgical therapy by retroauricular approach. The removed bone change was about 12 mm high, 13-14 mm deep and about 8 mm wide. Histopathological findings confirmed osteoma. Conclusion. Due to their slow growth, the rate of auditory canal osteomas develop asymptomatically for a long time without the characteristic clinical features. In most cases, they are discovered accidentally during otoscopic or radiographic examination. The method of choice in diagnosis is temporal bone CT scan. Therapy is surgical.

Abstract Aim The aim of the present paper is to report a case of benign cementoblastoma (BC) involving multiple maxillary teeth and discuss the importance of its diagnosis in clinical oral practice. Background BC is a rare, benign odontogenic neoplasm of ectomesenchymal origin. This neoplasm has characteristic radiologic and microscopic features, and it is intimately associated with the roots of teeth. Case Report The intra-oral examination in a 21-year-old white man revealed a palatine growth in the premolar-molar region. Dental panoramic and periapical radiographies showed a mixed radiodense/radiolucent lesion closely associated with the roots of three maxillary teeth. A biopsy was undertaken and confirmed the clinical hypothesis. Summary In most cases, initial BC is asymptomatic and early diagnosis can be performed by routine radiographic examination. BC was considered as an indolent lesion for several years. Nevertheless, recent studies have demonstrated that some BCs may exhibit aggressive biological behavior and can affect several teeth. Clinical Significance Because a benign cementoblastoma represents an odontogenic lesion, general practicing professionals must be able to identify the main features of this tumor. This case corroborates some papers that have demonstrated a possible aggressive behavior of BC. Therefore, a brief update concerning the clinical and radiographic features of this unique tumor is also provided.

Ameloblastic fibroma is an uncommon mixed neoplasm of odontogenic origin with a relative frequency between 1.5 – 4.5%. It can occur either in the mandible or maxilla, but predominantly seen in the posterior region of the mandible. It occurs in the first two decades of life. Most of the times it is associated with tooth enclosure, causing a delay in eruption or altering the dental eruption sequence. The common clinical manifestation is a slow growing painless swelling and is detected during routine radiographic examination. There is controversy in the mode of treatment, whether conservative or aggressive. Here we reported a 38 year old male patient referred for evaluation of painless swelling on the right posterior region of the mandible associated with clinically missing 3rd molar. The lesion was completely enucleated under general anesthesia along with the extraction of impacted molar.

Unusual Case Report

Ameloblastoma is a benign odontogenic neoplasm which frequently affects the mandible. The term ameloblastoma includes several clinicoradiological and histological types. Apart from the most commonly encountered clinicopathologic models, there are few variants, whose biological profile is unknown or not elicited. Among these types, unicystic ameloblastoma is the least encountered variant of the ameloblastoma. Unicystic ameloblastoma refers to those cystic lesions that show clinical, radiographic, or gross features of a jaw cyst but on histologic examination show a typical ameloblastomatous epithelium lining the cyst cavity, with or without luminal and/or mural tumor proliferation. Unicystic ameloblastoma is a less encountered variant of the ameloblastoma and is believed to be less aggressive. As this tumor shows considerable similarities with dentigerous cysts, both clinically and radiographically, the biologic behaviour of this tumor group was reviewed. Moreover, recurrence of unicystic ameloblastoma may be long delayed, and a long-term postoperative followup is essential for proper management of these patients. Here we are presenting a case of unicystic ameloblastoma in an 18-year-old female patient.
