Odontogenic tumor is a lesion originated from epithelium, ectomesenchymal, or mesenchymal component which still retain part of dental-forming element.A female 20 years old had complaint a mass in the oral cavity and obtructed nasal. Physical examination showed a mass on molar region of the left axillary bone. Diagnostic imaging by using OPG was suspected ameloblastoma, while CT scan concluded as a dentigerous cyst in left maxillary bone. Both of the lesions were cystic  abnormalities, that sometimes very difcult to di?erentiate due to their similarity. Pathological fndings was clear cell odontogenic tumor or clear cell odontogenic carcinoma of tissue mass after resection had been conducted. This case report is proposed because there is a discordance from imaging examination in both OPG and CT Scan with the fnal histopathological examination. CCOC di?erential diagnosis will be outlined here so we can understand the feature of CCOC better in imaging examination to prevent misdiagnosis which can infere further treatment.

ABSTRACT A 20-year-old female reported with chief complaint of pain in the left mandibular third molar region. Intraoral examination revealed inflamed area was notice near the retromolar area. Radiological examination showed impacted left third molar with pericoronal radiolucency of about 2.5 mm. Surgically, a very small cystic cavity was noticed surrounding the crown of the impacted third molar. Histopathological examination revealed a small cystic space lined by epithelium of two to three cell layers thick. The final diagnosis of dentigerous cyst was made. Thus, odontogenic lesion may be found in radiographically normal follicular space. How to cite this article Sarode GS, Sarode SC, Patil S. Expect the Exceptional. World J Dent 2014;5(3):196-197.

Abstract Context.—Odontogenic tumor composed predominantly of clear cells is a rare neoplasm of the jaws that was initially designated as clear cell odontogenic tumor. Subsequent reports in the literature, however, all have indicated that this tumor exhibits an aggressive behavior characterized by infiltrative local growth, recurrence, or metastases. Objective.—To ascertain the clinicomorphologic features and biologic behavior of this tumor group, we present 5 additional cases using the term clear cell odontogenic carcinoma. Design.—Histologic and immunohistochemical examinations were performed on clear cell odontogenic carcinomas from 5 patients. Clinical and follow-up data were recorded, and the literature was reviewed. Results.—The patients were 1 man and 4 women with an average age of 42.4 years at diagnosis. Three tumors occurred in the mandible and the other 2 in the maxilla. Four of the 5 cases occurred in the anterior or premolar areas of the jaws, appearing as poorly marginated radiolucencies. All cases consisted of islands and sheets of large clear cells and small basaloid cells with scanty eosinophilic cytoplasm, which were separated by thin, mature, fibrous septae. The tumors were unencapsulated and showed aggressive infiltration of the surrounding muscle and perineural tissues. Most of the clear cells contained cytoplasmic glycogen. Immunocytochemically, the tumor cells were positive for pan-keratin, cytokeratin 19, and epithelial membrane antigen, but were negative for vimentin, S100 protein, desmin, smooth muscle actin, human melanoma antigen (HMB-45), and α1-antichymotrypsin. Follow-up data showed 4 of 5 patients to have multiple local recurrences, and 1 of these 4 had submandibular lymph node metastasis and a fatal outcome due to uncontrollable tumor growth. Conclusion.—These results suggest that odontogenic clear cell neoplasms are at least low-grade malignancies and should be classified as carcinomas.

Clear Cell Odontogenic Carcinoma (CCOC) is a slow-growing, locally invasive odontogenic tumor affecting the jaws. It usually has confusing clinical characteristics, radiographical and histological features, making its recognition more challenging. In (2005), the WHO has reclassified CCOC as a malignant odontogenic tumor due to its aggressive behavior. This case report is about a woman who aged 42 years old, experienced swelling of the lower jaw and complained of paresthesia of the lips for two years. Radiographic findings showed an extensive, large, multilocular radiolucency lesion associated with scalloping, non-sclerotic border, and crossing the midline of the mandible. Histopathologically, the high-power view illustrated lobules of clear epithelial cells with clear cytoplasm. A review of English literature in PubMed Medline revealed few similar cases of CCOC affecting the mandible. The definitive diagnosis was consistent with CCOC; therefore, the patient was admitted to the hospital and surgical resection of the mandibular tumor was performed under general anesthesia. Long-term follow-up visits showed no signs of recurrence or post-surgical complications. We explain the signs and symptoms of CCOC such as symptomatic or asymptomatic jaw swelling, teeth loosening, displacement and mobility of teeth, and thinning of the mandible. Also, differential diagnosis and the nature of CCOC under the microscope were discussed and explained. The presentation of clear cell tumors is challenging, and it needs a meticulous investigation to determine the type of the tumor for proper diagnosis and management. CCOC should be included in the differential diagnosis list of jaw swelling that associated with slow-growing mass and paresthesia in the affected jaw.

Clear cell odontogenic carcinoma (CCOC) is a rare odontogenic tumor associated with aggressive clinical behavior, metastasis and low survival. We report a case of CCOC affecting the maxilla of 62 year-old woman. It was first described as a clinicopathological entity in 1985 and to date only 67 cases were described in the English literature. We are understanding of the behavior of this carcinomas was depend on limited case reports. For these reason we found important to report this case of CCOC in the maxilla.

Primordial odontogenic tumor (POT) is a rare odontogenic tumor characterized by a variably cellular loose fibrous tissue with areas similar to the dental papilla and covered by cuboidal to columnar epithelium. We herein report a case of POT in a 14-year-old boy. Computed tomography (CT) exhibited a round cavity with a defined cortical border circumscribing the tooth of the second molar. However, the gross finding was a solid mass, not a cyst. Histologically, the tumor consisted of dental papillalike myxoid connective tissue covered by columnar epithelium. Therefore, although the clinical diagnosis was dentigerous cyst (DC), we diagnosed POT based on histologic findings. Clinical findings of POT resemble DC, but the clinical behavior of POT is different to DC, such as cortical expansion and root resorption of teeth. Therefore, histological differentiation of POT from DC is critical for accurate diagnosis.
