각화낭성 치성종양은 국소적으로 공격적이고, 높은 재발률을 가지며 뚜렷한 조직학적 특성이 있는 낭성 병소로 다양한 치료 방법이 사용되고 있다. 몇몇 학자들은 공격적인 형태의 치료방법을 주장하지만, 또 다른 학자들은 보존적인 치료를 선호한다. 본 증례들은 미맹출 치아를 가진 소아 환자들에게 보존적 외과적 방법인 조대술과 낭종 적출술을 이용하여 각화낭성치성종양을 치료하였고, 주기적인 검진을 시행중에 있다. 보존적 외과적 치료를 이용하여 각화낭성 치성종양을 치료하는 경우 치아와 해부학적 구조를 보호할 수 있어 소아 청소년 환자의 경우에게 좋은 치료 선택이 될 수 있다.

Pseudoaneurysms are rare complications of orgthognathic surgery, trauma or other surgical procedures in the head and neck regions. Surgical approach is a routine procedure of bleeding control. However, bleeding control using angiography and embolization can also be an excellent method. We experienced pseudoaneurysm of the inferior alveolar artery occurring after surgical curettage of cystic lesion. The 33-year-old man who underwent surgical curettage of keratocystic odontogenic tumor was presented with severe bleeding in the right mandible ramal inner surface 14 days after the surgical curettage. After hemostasis with vaseline gauze packing and pressure, bleeding temporarily stopped. However, bleeding started after 14 days and soon it has been continued. Finally, the patient was diagnosed as pseudoaneurysm of the inferior alveolar artery from the enhanced-computed tomography images, and angiographic embolization was performed successfully. We report a rare case of pseudoaneurysm of the inferior alveolar artery after benign tumor curettage and review of the previewer's literature.

Clear cell odontogenic carcinoma (CCOC) is a rare jaw tumor that was classified as a malignant tumor of odontogenic origin in 2005 by the World Health Organization because of its aggressive and destructive growth capacity and metastasis to the lungs and lymph nodes. We report a case of a 66-year-old female who had swelling, incision and drainage history and a well-defined unicystic radiolucent lesion that was comparable to a cystic lesion. At first, the patient received decompression, and the lesion size decreased. Three months after decompression, cyst enucleation was performed. The pathologic result indicated that the lesion was CCOC. In this report we emphasize that patients with painful cystic lesions in addition to jaw enlargement and loosening teeth should be considered for the possibility of malignancy.

Amyloid-producing odontogenic tumors were described in the gingival masses of two Maltese dogs. Gingival masses were surgically removed and submitted for diagnosis. On histopathology, the masses were poorly demarcated, infiltrative, and consisted of cuboidal and columnar epithelial cells with palisading pattern. Nodular deposit of congophilic amyloid-like material and mineralization were another features of the tumors. Immunohistochemically, the neoplasticd cells were positive to pancytokeratin and neuron-specific enolase but were negative to vimentin. The amorphous homogeneous eosinophilic materials were positive to Congo red stain and showed apple-green color under the polarized microscope. Based on these results, both cases were diagnosed as amyloid-producing odontogenic tumors in dogs.

The auhors have studies clinically and histopathologically on the 6 rare cases of odontogenic myxoma or fibromyxoma of the jaw which were obtained from 72 odontogenic tumor of Biopsy cases during 10 years from 1961 to 1971 at the Dept. of Oral Pathology, college of Dentistry, Seoul National University. The results are are follows; 1. In 72 cases of odontogenic tumor, myxoma or fibromyxoma were 6 cases (8.34%) 2. 4 cases in 6 cases of myxoma (fibromyxoma) were occurred in male and 2 cases were in female, and the median age of 6 cases was 27 and the age range was 4 to 44. In the location, each 3 cases located in upper and lower jaw. 3. All 6 cases were occurred in jaws with central origin by expansive slowly growth, painless. the operation prognosis was almost good without one case. 4. The histopathological findings of 6 cases consists of loosely arranged stellate shaped cells with long, anastomosing cytoplasmic process. The cytoplasm of these cells are basophilic poorly stain and nuclei are avoid and hyperchromic.

Clear cell odontogenic carcinoma (CCOC), a very rare neoplasm located mostly in the mandible, has been regarded as a benign tumor. However, due to the accumulation of case reports, CCOC has been reclassified as a malignant entity by the World Health Organization. Patients with CCOC present with regional swelling and periodontal indications with variable pain, often remaining misdiagnosed for a long period. CCOC has slow growth but aggressive behavior, requiring radical resection. Histologic analysis revealed the monophasic, biphasic, and ameloblastic types of CCOC with clear cells and a mixed combination of polygonal and palisading cells. At the molecular level, CCOC shows the expression of cytokeratin and epithelial membrane antigen, along with markers that assign CCOC to the sarcoma family. At the genetic level, Ewing sarcoma breakpoint region 1-activating transcription factor 1 fusion is regarded as the key feature for identification. Nevertheless, the scarcity of cases and dependence on histological data delay the development of an efficient therapy. Regarding the high recurrence rate and the potential of distant metastasis, further characterization of CCOC is necessary for an early and accurate diagnosis.
