Abstract Chondroma is uncommon in the oral region. It usually occurs in the hard palate, alveolar ridge, condyle, or coronoid process. Only a few cases of oral extraskeletal chondroma have been reported,1–8 the most common site being the tongue. We report an additional case of chondroma involving the tongue and present a brief review of the subject.

This study is based on an analysis of biopsy specimens that were diagnosed histopathologically in the Department of Oral Pathology, Tokushima University School of Dentistry from 1979 to 1983. This paper is presented with special reference to the tumorous lesion in this series.1. The total number of the specimens related to tumorous lesions during these five years were 465 and corresponded to 198 cases. Of the 198 cases, 22 cases represented odontogenic tumors, 148 cases revealed non-odontogenic tumors and 28 cases were diagnosed as salivary gland tumors.2. The most common cases of odontogenic tumors were ameloblastoma (8 cases) followed by odontoma (7 cases). In this series, ameloblastoma was less frequent and older compared with that of other reports.3. In the non-odontogenic tumors, benign tumors showed in 58 cases and malignant tumors showed in 90 cases. The benign epithelial tumors were all in papilloma. In the benign nonepithelial tumors, the most common tumors were hemangioma (25 cases), followed by osteoma (7 cases). About 89% of the malignant tumors were squamous cell carcinoma. The most common site of these were found on the tongue followed by the maxillary sinus and the gingiva.4. As for salivary. gland tumors, there were 19 cases of benign tumors and 9 cases of malignant ones. The most common site was found in the palate and 57% of the salivary gland tumors revealed the pleomorphic adenoma.

This study is based on an analysis of biopsy specimens that were diagnosed histopathologically in Department of Oral Pathology, Tokushima University School of Dentistry from 1979 to 1983.1. The total number of the specimens during this five years were 1, 624 and it corresponded to 1, 248 cases (patients).2. About 66.4% of all the specimens in this series were represented by the 20 different types of common lesions. About 17.5% of the 1, 624 specimens were squamous cell carcinoma, 10.0% were radicular cysts and 6.3% were mucous cysts.3. The most common cases of the 1, 248 patiens were radicular cysts which showed about 12.4% of all the cases, followed by 7.5% of mucous cysts and 6.8% of squamous cell carcinoma.4. Therefore, a number of the specimens per each case were many in the malignant tumors.5. The cystic lesions revealed the largest group in this series, and composed 467 cases (37.5%) of all 1, 248 cases. The tumorous lesions followed with 198 cases (15.9%) of all the cases.
