  • Carcinomas derived from ameloblastomas have been designated by a variety of terms, including malignant ameloblastoma, ameloblastic carcinoma, metastatic ameloblastoma, and primary intra-alveolar epidermoid carcinoma. The term of ameloblastic carcinoma is differentiated from the term of malignant amelblastoma and is defined as an ameloblastoma in which there is histologic evidence of malignancy in the primary tumor or the recurrent tumor(or metastasis), regardless of whether it has metastasized. The well-documented and adequately followed cases are currently lacking and this report described an instance of ameloblastic carcinoma with good result after treatment and review of literature.

  • The authors diagnosed a 54-year-old male as central mucoepidennoid carcinoma after undergoing clinical, radiological and histopathological examinations. The characteristics were as followed : 1. Clinically, the patient complained of the painless unilateral swelling of the left mandibular molar region and had a pus discharge through the fistula. Painful nodule was palpated on the scalp of the left frontal area and it was regarded as a metastatic lesion. 2. Plain radiographs showed the ill-defined permeative radiolucent lesion. The osteolytic lesions were also detected in the cranial bone, number 9 and 11 ribs, scapula, and vertebral bodies. 3. The mandibular CT and PNS MRI showed the swelling of the left mandible and the enlargement of the several lymph nodes of 1.5 cm in size. 4. Histopathologically, many solid epidermoid type cells were mixed with mucus-secreting cells and they were arranged in duct-like structure. Most of them were epidermoid type, which indicates a high grade tumor. Mucins could be found in mucicamrine staining.

  • Sophora flavescens AITON (Leguminosae) is a typical traditional Korean medical herb considered to exhibit antibacterial, anti-inflammatory, and antipyretic effects, and is also used for the treatment of skin and mucosal ulcers, sores, diarrhea, gastrointestinal hemorrhage, arrhythmia, and eczema. In this study, the compound sophoraflavanone G was isolated from the dried roots of S. flavescens by bioassay-guided fractionation. We then investigated the effects of various concentrations of sophoraflavanone G on cell viability and the induction of apoptosis in KB cells after an incubation of 24 hr. The results were determined by the following methods: 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-terazolium bromide (MTT) assay, Hoechst-33258 dye staining, flow cytometry (cell cycle), and Western blotting for caspase-3 and poly (ADP-ribose) polymerase (PARP). We found sophoraflavanone G induced the apoptosis of KB cells in a dose-dependent manner that was verified by DNA fragmentation, apoptotic bodies, the sub-G1 ratio, caspase-3 activity, and cleavage of PARP. These results suggest that sophoraflavanone G has potent anti-proliferative effects on human oral epidermoid carcinoma cells, with the induction of apoptosis.

  • The mucoepidermoid carcinoma of the bronchus is very rare neoplasm. The histological appearance is an intimate mixture of mucous-producing cell and epidermoid cell. The malignant potency of the tumor was determined by histologic pattern. Bronchoplasty techniques represent the ideal form of excisional therapy for benign endobronchial tumor as well as tumors of low-grade malignant potential, such as bronchial adenoma, and for repair of traumatic airway injuries and benign stricture and selected group of patients with carcinoma of the lung. We experienced a case of-low-grade mucoepidermoid carcinoma in a patient of 21-year old male who has been suffered from hemoptysis episodes for several years. The sleeve resection of left main bronchus and left lower lobectomy due to bronchiectatic change were carried out. The patient are being followed up without specific problem.

  • Mucoepidermoid carcinoma occurs more freguently than any other in the major sacivary glands. It is relatively more common in parotid than in submandibular gland. Stewart at al published the first large series of these tumors in 1945 and suggested the name "Mocoepidermoid tumor". Now it is divided three categories : low-grade, intermediate-grade, high-grade. And Mucoepidermoid carcinomas are composed of mucous cells, epidermoid cells, and intermediate cells. We freated low-grade mucoepidermoid carcinoma patient with induction chemotherapy, surpery, and adjuvomt chemotherapy.

  • Background: Parathyroid hormone-related protein(PTHrp) was first identified as the cause of hypercalcemia in malignancy. Hypercalcemia can be found in malignancy, especially in the epidermoid carcinoma of the lung, even without extensive metastases to the bones. The application of sensitive assays for PTHrp may help in the early diagnosis of lung cancer, in the monitoring of treatment and in the detection of recurrence. Method: Serum PTHrp was measured by radioimmunoassay detecting the N-terminal 1~34 peptide of human PTHrp(PTHrp 1-34) in 63 histologically confirmed lung cancer patients and 22 healthy controls. Result: Serum PTHrp(mean$\pm$S.E.) was $312{\pm}68.9pg/ml$ in 63 lung cancer patients and $158{\pm}38.2pg/ml$ in 22 controls(p>0.05). PTHrp was $356{\pm}103.9pg/ml$ in 34 epidermoid carcinoma patients, $281{\pm}148.7pg/ml$ in 15 adenocarcinoma patients and $316{\pm}140.8pg/ml$ in 9 small cell carcinoma patients. In epidermoid carcinoma patients, PTHrp was $570{\pm}472.3pg/ml$ in stage II(n=3; p<0.05 vs controls), $166{\pm}22.4pg/ml$ in stage IIIa(n=9), $282{\pm}113.3pg/ml$ in stage IIIb(n=12) and $668{\pm}367.9pg/ml$ in stage IV(n=9; p<0.05 vs controls). PTHrp was significantly increased in 8 epidermoid carcinoma patients with bone metastases($1526{\pm}811.2\;pg/ml$; p<0.0005 vs controls). Hypercalcemia was observed in an epidermoid carcinoma patient whose PTHrp value was 244 pg/ml. Conclusion: The serum PTHrp was increased in advanced epidermoid carcinoma patients even without hypercalcemia. The measurement of PTHrp may be not helpful in the early diagnosis of lung cancer. But the lung cancer should be suspected in the marked elevation of PTHrp. It may be of value in detecting patients of advanced diseases with bone metastases or patients who might develop the malignancy associated hypercalcemia.

  • Authors experienced a case of intermediate grade mucoepidermoid carcinoma in 29-year-old female. The origin of this tumor might be mucus secreting cells of palatal mucous gland. The characteristic features were as follows: 1. In clinical examination, exopytic mass was observed in left hard palate and similar to pleomorphic adenoma. 2. In radiographic findings, destructive changes of left hard palate, nasal septum, nasal inferior turbinate and floor of maxillary sinus and soft tissue mass were observed. 3. Histopathologically, mucus-secreting cells, epidermoid cells and intermediate cells were observed and diagnosed as intermediate grade mucoepidermoid carcinoma.
