  • The peripheral odontogenic fibroma (WHO type) is a relatively rare and characteristically benign and unencapsulated, exophytic gingival mass of fibrous connective. Odontogenic epithelium is found within the gingival mass, but usually appears to playa minor role when compared to the fibrous component. The connective tissue is ranged from markedly cellular to relatively acellular and well collagenized. but the connective tissue in this case report appears less cellular. Peripheral odontogenic fibroma must be differentiated histologically from peripheral ossifying fibroma, Peripheral cemental epithelial odontogenic tumor and Peripheral ameloblastoma. The author reports the following conclusions after clinical and radiological examination, excisional biopsy and reviewing literatures. 1. Peripheral odontogenic fibroma is rare lesion and frequently occurs in interdental papila as a form of fibroblastic connective tissue including odontogenic epithelium within the lesion. 2. Peripheral odontogenic fibroma must be differentially diagnosed with Peripheral ossifying fibroma by including less cellular connective tissue, odontogenic epithelium and dysplastic dentin 3. Treatment consists of surgical excision including removal of alveolar bone which is eroded under the lesion

  • The animal in this case report was a 10-year-old male Taiwanese monkey (Macaca cyclopis) kept at a zoo of South Korea. Over the last three years, a cauliflower-shaped masses have been noted on the gingiva near the incisor and molar teeth on right maxilla. Consequently, this monkey have undergone surgical removal of the mass annually. Grossly masses showed pinkish color. Histopathological findings, typical spindle cell tumor composed of collagen fibers. Infiltration by plasma cells and lymphocytes is found unrelated to ulceration of the surface epithelium. This is the first report of peripheral odontogenic fibroma in a Formosan rock macaque.

  • The authors experienced one case of peripheral giant cell granuloma occurred at the gingiva of right maxillary molar in a 12-year-old male patient. The lesion showed amorphous calcification within soft tissue mass which made difficult to differentiate this lesion from peripheral ossifying fibroma and peripheral odontogenic fibroma clinically and radiographically. The final diagnosis was made histologically.

  • Purpose : 1. Retrospectively evaluate the accuracy of tentative diagnosis or impression from the clinico-radio-graphic materials of jaw lesions which showed mixed lesions associated with teeth. 2. To observe the diagnostic importance of the calcified part of the lesions which appear as radiopaque areas. Materials and Methods: 14 cases of jaw lesions which showed mixed lesions associated with teeth were reviewed. These lesions were mostly diagnosed as adenomatoid odontogenic tumors (6 cases) or calcifying odontogenic cysts with (4 cases) or without odontomas (4 cases). The calcified elements of the lesions which demonstrated various sizes and patterns of radiopaque shadows resembled odontoid tissues in some cases but could not be defined in some other cases radiographically. Results : The final histopathologic diagnosis confirmed adenomatoid odontogenic tumors in 4 of the 6 cases. The remaining 2 cases turned out to be odontoma and ameloblastic fibroodontoma. The 4 cases of calcifying odontogenic cysts with odontomas were correct in 3 cases but remaining 1 case was just odontoma. The 4 cases of calcifying odontogenic cysts were proved to be odontogenic keratocyst, calcified peripheral fibroma, unicystic ameloblastoma and squamous cell carcinoma. Conclusion : The diagnostic accuracy of the adenomatoid odontogenic tumors and calcifying odontogenic cysts were high when the lesions show typical appearance. The calcifications which show radiopaque areas could be odontomas or dystrophic calficifations or remnants of bone fragments from resorption.
