Sclerosing odontogenic carcinoma (SOC) was first described by Koutlas . in 2008. Despite its inclusion in the World Health Organization (WHO) as a distinct entity, it is a tumour that remains poorly defined in the literature, with only 10 reported cases to date. The mandibular premolar and molar region is more commonly affected compared to the maxilla. In the maxilla, the anterior and the molar regions are most commonly affected. This article describes a case report of a Sclerosing Odontogenic Carcinoma in a 50 year old male patient in the mandibular region. The radiograph showed a well-defined radiolucency extending from the left ramus of the mandible to the right lower molar region. SOC is low grade with mild atypia and frequent mitosis and diffused infiltrative and perineural spread.

Peripheral odontogenic fibroma (POF) is described as a relatively rare, benign, extraosseous odontogenic tumor derived from odontogenic ectomesenchyme. It is characterized by a mature fibrous stroma with embedded inactive resting islands of odontogenic epithelium. In the category of peripheral/extraosseous neoplasms, odontogenic fibroma (OF) is one of the most prevalent tumors. The radiographic examination shows minimum bone loss in the alveolar crest area. It poses a diagnostic challenge for clinicians and pathologists because its clinical and radiological aspects are similar to other peripheral odontogenic as well as non-odontogenic tumors, and the differential diagnosis is predicated on histological assessment. Histopathological examination is the key to a final confirmed diagnosis. This article presents a case report of a 53-year-old male who reported a painless, pale pink mass in the maxillary anterior region. We emphasize the clinicopathological, radiographical, and histopathological aspects of the rare entity of POF.

Sturge-Weber syndrome (SWS) is a neurocutaneous syndrome with vascular lesions of the cerebral meninges, port wine spots on the face, and glaucoma of the eyes; it is a congenital, non-genetic disease whose etiology and mechanisms are unknown. In this report, we describe a rare case of SWS with unilateral large odontogenic tumors in the maxilla and mandible. The histopathological diagnosis of the maxillary bone lesion on biopsy was juvenile psammomatoid ossifying fibroma, which is considered a type of ossifying fibroma of craniofacial bone origin. However, the final pathological diagnosis of the excision was cemento-ossifying fibroma derived from periodontal ligament cells, and we discuss the histopathology in detail. In addition, the mandibular lesion was one of the largest odontomas reported to date. Furthermore, in this case, we suggest the possibility that the maxillary and mandibular bone lesions are not separate lesions, but a series of lesions related to SWS.

Cemento-ossifying fibroma (COF) is a mesenchymal benign odontogenic tumor, which may lead to impacted or ectopic permanent teeth. Autotransplantation of teeth is a surgical process, in which a tooth is transplanted from one position to another in the same individual. This method can effectively restore the patient's mastication and aesthetics and is feasible in replacing missing teeth. This study reports a case of simultaneous COF resection combined with heterotopic canine autotransplantation to repair dentition defect, which effectively promotes the restoration of bone continuity and stability and achieves immediate and long-term aesthetic function requirements.

Ossifying fibroma (OF) is a slow-growing benign fibro-osseous neoplasm. It is mostly odontogenic in origin, and it arises in the jaws, particularly the mandible. OF is characterized by the production of bone and cementum-like calcifications in a fibrous stroma. OF reports of the bone of the maxilla are uncommon. Diagnosing OF can be challenging due to the considerable overlap of clinico-pathological characteristics with those of other neoplasms. Herein, the authors describe a case report OF in a 26-year-old male who presented with a huge fibro-osseous tumor of the maxilla. Histopathology established the diagnosis of maxillary OF. The tumor was surgically removed via a Weber-erguson approach with satisfactory functional and cosmetic results. No recurrence has been found after one year of follow-up. Clinical, radiological, and pathological characteristics, as well as surgical treatment approaches, are further discussed. This is one of a few documented cases of maxillary OF in our setting.

Fibro-osseous lesions (FOLs) of the craniomaxillofacial region comprise a group of developmental, dysplastic, and neoplastic alterations. FOLs include ossifying fibromas (OF), cemento-ossifying fibroma (COF), familial gigantiform cementoma (FGC), fibrous dysplasia (FD), and cemento-osseous dysplasia (COD). Evidence suggests that some FOL, especially FD and OF may have a risk of spontaneous malignant transformation. This report documents a rare case of malignant transformation of ossifying fibromas of the jaw and the probable cause for same. Although it is rare, the clinician should have a complete follow up to observe such changes among the patients having FOLs.

Fibroma is a benign fibrous tissue growth that develops in response to injury or irritation. It is usually firm, painless, nodular, and merging in color with the surrounding tissue. Commonly located in areas such as the buccal mucosa, tongue, and lip, the usual treatment involves surgical removal. In this case report, we present a rare instance of misdiagnosed extraoral irritational fibroma that emerged following the surgical extractions of the lower left third molar.

OBJECTIVE
Although Gorlin syndrome has rich skin findings, there is limited information about their subtypes, features specific to this genodermatosis, and relationships with each other.
MATERIALS AND METHODS
The demographic characteristics as well as cutaneous and extracutaneous findings of consecutive Gorlin syndrome patients diagnosed during 23 years were evaluated retrospectively. The relationship between palmoplantar pitting and basal cell carcinoma (BCC) in this localization and the relationship between odontogenic keratocysts (OKCs) and epidermoid cysts were investigated.
RESULTS
A total of 30 patients were diagnosed with Gorlin syndrome of whom 36.7% were children. BCC was the most common finding (90%) followed by OKCs (83.3%), skeletal system anomalies (76.7%), and palmoplantar pitting (76.7%). While classical BCC (63.3%) lesions were the predominant clinical subtype among all patients, acrochordon-like or small-sized papular BCCs were seen in 45.4% of pediatric patients. Three patients, 2 of whom were children, had BCC lesions in the palmoplantar region in association with palmoplantar pitting. Epidermoid cysts presenting clinically as solitary (n = 12) or a few nodules (n = 4) without punctum, located more commonly in acral areas (n = 10) were seen in 16 (53.3%) patients of whom 7 were children. Epidermoid cysts were seen in 60% of patients with OKCs, and the relationship between epidermoid cysts and OKCs was not statistically significant (P = .15). Extracutaneous tumors such as medulloblastoma (n = 3), cardiac fibroma (n = 1), and ameloblastoma (n = 1) were also recorded.
CONCLUSION
The awareness of papular or acrochordon-like BCCs, palmoplantar BCCs, and acral epidermoid cysts without punctum may facilitate early diagnosis of Gorlin syndrome in children.

This case report discusses a 28-year-old patient who presented with a large expansile lesion of the right mandible. A maxillofacial CT showed a 6.7 x 9.1 x 7.6 cm right mandibular cystic mass containing an internal matrix of ground glass bone, representing a huge odontogenic keratocyte. Upon biopsy of the lesion, the specimen consisted of non-decalcified irregular fragments of cemento-osseous material, embedded in a minimally hemorrhagic, cellular fibrous tissue stroma, suggestive of central ossifying fibroma. This case presents an ossifying fibroma that far exceeds the average size of these masses, which typically range from 1.0 to 2.5 cm at its greatest dimension. The immense size of the lesion seen in this case is rarely encountered. This case also helps to emphasize the importance of timely diagnosis and complete resection of the lesion to prevent mass recurrence and possible malignant transformation.

BACKGROUND
Since there are many differential diagnoses for cemento-osseous dysplasia (COD), it is very difficult for dentists to avoid misdiagnosis. In particular, if COD is related to an embedded tooth, differential diagnosis is difficult. However, there have been no reports on the characteristics of the imaging findings of COD associated with embedded teeth. The aim of the present study was to investigate the occurrence and imaging characteristics of cemento-osseous dysplasia (COD) associated with embedded teeth, in order to appropriately diagnose COD with embedded teeth.
METHODS
The radiographs with or without histological findings of 225 patients with COD were retrospectively analyzed. A retrospective search through the picture archiving and communication system (PACS) of the Division of Oral and Maxillofacial Radiology of Kyushu Dental University Hospital was performed to identify patients with COD between 2011 and 2022.
RESULTS
Fifteen COD-associated embedded mandibular third molars were identified in 13 patients. All 13 patients were asymptomatic. On imaging, COD associated with embedded mandibular third molars appeared as masses that included calcifications around the apex of the tooth. On panoramic tomography, COD showed inconspicuous internal calcification similar to that of odontogenic cysts or simple bone cysts, especially in patients with COD only around the mandibular third molar region. Those with prominent calcification resembled cemento-ossifying fibroma, calcifying epithelial odontogenic tumor, calcifying odontogenic cyst, adenomatoid odontogenic tumor, and so on, as categories of masses that include calcifications on panoramic tomography and computed tomography.
CONCLUSIONS
The current investigation is the first to report and analyze the imaging characteristics of COD associated with embedded teeth. It is important to consider the differences between COD and other cystic lesions on panoramic tomography, and the differences between COD and masses that include calcifications on CT.
