Abstract: Calcifying cystic odontogenic tumor (CCOT) is an uncommon benign cystic neoplasm of the jaw that develops from the odontogenic epithelium. It is clinically characterized as a painless—slow-growing tumor that affects the maxilla as well as the mandible, and generally occurs in young adults in the third or fourth decade of life. Herein, we present the case of a 16-year-old Japanese boy who showed a CCOT in the maxillary sinus. Panoramic radiography showed a unilocular lesion in the left maxillary sinus. Computed tomography showed an approximately 5-cm well-defined unilocular expansile lesion with multiple radiopaque calcific specks, arising from the left maxillary alveolar ridge. The lesion was surgically removed, under general anesthesia, and the patient was followed up for 3 years after the surgery, and there have not been any signs of recurrence.

Abstract: The calcifying epithelial odontogenic tumor (CEOT) is a rare and benign odontogenic epithelial neoplasm. This tumor accounts for less than 1% of all odontogenic tumors. It normally affects patients between 30 and 50 years old, and it is typically located in the posterior region of the mandible. Involvement of the maxillary sinus has previously been published only in six cases. This report presents a single case of CEOT that invades the maxillary sinus in a 69-year-old male. We performed a left partial maxillectomy and immediate reconstruction of the defect with a temporalis muscle flap. A comprehensive immunohistochemical study was reported. No recurrences have been found after 8 years of follow-up.

Abstract: Introdution: Pigmented intraosseous odontogenic lesions are rare, with only 47 reported cases inthe English literature. Among them, pigmented calcifying cystic odontogenic tumor, formerly knownas calcifying odontogenic cyst, is the most common lesion with 20 reported cases.Case Report: The patient was a 19-year-old man. He had a bony, tender expansion in anteriorright maxillary region extended to orbital rim with visual complaints and unilateral headache.Considering radiographic appearance, microscopic study, special and immunohistochemicalstaining, a diagnosis of pigmented calcifiying cystic odontogenic tumor associated with odontomawas rendered.Conclusion: Due to the same neural crest origin for melanocytes and dental lamina, the presenceof melanocytes and melanin in this lesion is accountable. However, till now, no biologic behavioraland prognostic role has been considered for it. This case will add to rare reported cases ofpigmented odontogenic lesions.Key words: Pigmented calcifying cystic odontogenic tumor, Odontoma, Melanocyte

Abstract: The Calcifying Cystic Odontogenic Tumor(CCOT) is an uncommon lesion that demonstrates considerable histopathologic diversity and variable clinical behavior. A CCOT is rarely found in everyday practice. According to Kramer and Pindborg as well as majority of other authors’ classification, since 1992 the World Health Organization favored the use of the term calcifying cystic odontogenic tumor, described it as a cystic or neoplastic-like odontogenic pathological lesion of the jaw, and classified it as a benign odontogenic tumor. Ultrasonography(USG) is an inexpensive, non-invasive, and almost an available technique that is well tolerated by patient. In recent years many investigations focused on the use of ultrasonography in maxillofacial region as well as in intra osseous lesions of the jaws. This paper describes a 34 year old female with a painless mild swelling in the left anterior maxillary region associated with an impacted lateral incisor. The Panoramic, lateral occlusal and periapical view findings showed well-defined corticated unilocular mixed lesion with cluster of small pebbles calcifications. USG examination, using linear probe transducer, and also evaluation of location, size, internal echoe and boundary of the tumor were performed and documented. The main USG features of the tumor appeared as anechoic pattern cystic like lesion with some calcifying contents. Pathologic diagnosis was obtained by examining the surgical specimen. Therefore, ultrasonography may be used as an effective supplementary diagnostic tool for maxillofacial lesions.

Abstract: The calcifying odontogenic cyst was first reported by Gorlin et al . in 1962. It had been classified as a neoplasm related to the odontogenic apparatus because of its histological complexity and morphological diversity until it was renamed as a calcifying cystic odontogenic tumor by the WHO, in 2005. Here we describe a case of mandibular calcifying cystic odontogenic tumor in a 75-year-old male, which was present since five years, with a history of occurrence after the extraction of teeth in the involved region. The lesion was surgically removed and a histopathological examination revealed a cystic tumor with predominance of ghost cells and some amount of dentinoid tissue.

Abstract: Objective. We report the first utilisation of transnasal marsupialization to treat a keratocystic odontogenic tumor in the maxillary sinus of a 37-year-old man. Case Report. A 37-year-old man presented with a nasal discharge and right odontalgia. Computed tomography revealed an expanding cystic lesion with a calcificated wall containing an impacted tooth in the right maxillary sinus. The diagnosis was keratocystic odontogenic tumor. Transnasal marsupialization was performed using endoscopic sinus surgery to enlarge the maxillary ostium and remove a portion of the cystic wall. Pathological findings included lining squamous epithelium and inflammation. The remaining tumor shrank, becoming free of infection after surgery, without proliferation. Conclusion. Transnasal marsupialization using endoscopic sinus surgery is effective in treating keratocystic odontogenic tumors. It offers minimal surgical invasion and reductive change, making it advantageous for complete removal with fewer complications in the bones and surrounding tissue in the case of secondary surgery. 1. Introduction Odontogenic keratocysts were first reported by Philipsen in 1956 [1]. Odontogenic keratocysts are dentigerous cysts derived from the proliferation of residues of the dental lamina. Odontogenic keratocysts potentially behave aggressively, and the rate of recurrence is high, varying from 0 to 62% according to the various treatments [2]. In 2005, odontogenic keratocysts were reclassified by the World Health Organization as keratocystic odontogenic tumors and defined as benign unicystic or multicystic intraosseous tumors of odontogenic origin [3]. Many different treatments, ranging from simple curettage to highly invasive en block resection with extension margins, have been used. However, there is no consensus on the most effective method. We attempted a minimally invasive marsupialization procedure via a transnasal approach using endoscopic sinus surgery (ESS) for odontogenic keratocysts of the maxilla as a first stage operation. In this paper, we present the first case of a keratocystic odontogenic tumor in the maxillary sinus treated using ESS and discuss the effectiveness of surgery. 2. Case Report A 37-year-old man presented with a purulent nasal discharge and odontalgia on the right side of his face. The purulent discharge from the right gingiva began two years earlier and persisted despite dental treatment. The right inferior turbinate was swollen, and the lateral nasal wall protruded. Pus discharged from the right gingiva near the second molar. Dental caries were not detected

Abstract: The calcifying cystic odontogenic tumor normally presents as apainless, slow-growing mass, involving both maxilla and mandible,primarily the anterior segment (incisor/canine area). It generallyaffects young adults in the third to fourth decades, with no genderpredilection. Computerized tomography images revealed importantcharacteristics that were not detected by panoramic radiography,such as fenestration, calcification and tooth-like structures. Thetypical microscopic feature of this lesion is the presence of variableamounts of aberrant epithelial cells, without nuclei, which arenamed “ghost cells”. In addition, dysplastic dentine can be foundand occasionally the cyst can be associated with an area of dentalhard tissue formation resembling an odontoma. The treatment forcalcifying cystic odontogenic tumor involves simple enucleationand curettage. The purpose of this article is to present two differentmanifestation of calcifying cystic odontogenic tumor in whichcomputerized tomography, associated to clinical features, servedas an important tool for diagnosis, adequate surgical planning andfollow-up of patients.
