The prognosis of oral malignant melanoma is poor compared with cutaneous melanoma. It may be related to the difficulty of wide enough resection, the early hematogenous matastases, higher stage at initial diagnosis, and tendency to growth vertically. In the view of histological differences between oral mucosa and skin, it is impossible use Clark's and Breslow's classifications for prognosis. The great problem is that there is still no consensus on the treatment due to rarity. Because data collection from case reports is considered to be the best source of information and should be pooled to analyze key determinants of outcome, We analysed 6 cases of primary malignant melanoma of the oral cavity which were diagnosed and treated in Pusan National University Hospital on recent 7 years and reviewed the literatures. Immunohistochemical study on S 100 Protein, GP 100 (HMB-45) with biopsy was usable to confirm the melanoma. Three patients who were treated by surgery, chemotherapy are alive, but a patients who couldn't received benefit care surgically due to poor condition was died of distant metastasis, and two patients who refused to surgery are still alive. Neck dissection including wide excision is recommended if lymph node involvement is suspected. Additionally, adjuvant chemotherapy could be considered as supporting therapy for malignant melanoma.

Purpose: Angiosarcoma is a tumor of mesenchymal origin with an extremely high rate of metastasis and invasiveness. This tumor is notorious for its very poor prognosis, although surgical excision followed by radiation therapy is considered to be effective by many. The authors experienced three angiosarcoma patients with their tumors removed and wounds covered with split-thickness skin grafts and/or latissimus dorsi free flaps. Methods: Three patients were admitted to our hospital showed plaques of different morphology. Based on their medical records, these patients were classified by sex, age, type of reconstruction, recurrence, and further treatment after surgical removal. Results: All patients were male, with a mean age of 72 years (range, 66 to 77 years). Split-thickness skin grafts with latissimus dorsi free flaps were performed on two cases, and of these two cases, cervical lymph node biopsy was done in one case, and radical neck dissection was done in the other. In all cases, radiation therapy was done within two weeks of tumor removal. Distant metastasis occurred without local recurrence in two of the cases. Lung was the first organ affected by metastasis. In the remaining case, the tumor recurred locally 6 times, and additional excision was necessary. All patients died due to local recurrence and lung metastasis. Conclusion: Irregular margins and high recurrence and metastasis rates cause a poor prognosis in large angiosarcoma of the scalp. Radiotherapy and chemotherapy should be strongly considered in large angiosarcomas.

Tonsil is rich in lymphatics, blood vessels, muscle, nearby nerve fibers and epithelium. All of these are potential sources of malignancy. Malignancy of the tonsils is an uncommon entity that accounts for little more than 0.5% of new malignancies in the United States every year. Approximately, more than 70% of malignancies in this region are squamous cell carcinoma. In this report, I introduce a case of 47 year male patient who has right tonsillar cancer that is squamous cell carcinoma(T4N3M0). After three times chemotherapy, the patient refused to get conventional western medical treatment including chemotherapy and surgical operation. After 8 month of traditional oriental medical treatment using allegen removed Rhus Verniciflua Stokes(ARV), the size of cancer mass decreased and mass showed necrosis at inner portion. The patient improved pain in the neck. More case will be needed in order to determine the effect of ARV on tonsillar cancer.

Objectives : The purpose of this study is to investigate the effect of Gupoongjeseuptang (GPJST) on atopic dermatitis by in vivo experiment using NC/Nga atopic dermatitis mouse, which has histological and clinical similarities to the atopic dermatitis of human. Methods : To investigate the effect of GPJST on atopic dermatifis, we evaluated atopic dermatitis-like skin lesions by clinical skin index and analyzed immunological parameters in peripheral blood mononuclear cells (PBMCs), splenocytes, draining lymph node (DLN) and performed skin histology in ears and dorsal skin of atopic dermatitis-like skin NC/Nga mouse in vivo. Results : In vivo, clinical skin severity score were significantly lower in GPJST group than control group. IgE, IL-6, $TNF-{\alpha}$, IgG1, IgM, IgG2a and IgG2b levels in serum decreased remarkably in GPJST group than control group. Also, total absolute number of $CD3^+CD69^+$, and $CCR3^+$ cells recovered as normal in PBMCs and $CD3^+$, $CD3^+CD69^+$ decreased significantly compared with control group in isolated DLN from NC/Nga mouse and total absolute number of $CD11b^+Gr-1^+$, $CCR3^+CD3^+$ in dorsal skin of NC/Nga mouse decreased by GPJST. We analyzed ear and neck-back skin after biopsy and dyeing by hematoxyline/eosin (H&E) and toluidine staining (mast cells marker) and obtained results that GPJST are very effective to histological symptoms (dermal and epidermal thickening, hyperkeratosis and inflammatory cell (CD4, $CCR3^+$) infiltration). Conclusions : This study demonstrates immunological activity of GPJST on atopic dermatitis-like model mice.

Sixty-six patients with squamous cell carcinoma of the supraglottic larynx received irradiation with curative intent between 1979 and 1985 were retrospectively analysed. All patients had a minimum follow-up of 4 years. Of the entire group consisting of $73\%$T3 and T4 lesions and $58\%$ lymph node metastases, a 5-year acturial survival rate was $31.3\%$. A 5-year acturial survival rates for stage II, III and IV were $60.7\%,\;45.7\%\;and\;13.5\%$ respectively (p<0.05). Patients without lymphnode metastases had better survival rate than those with postive lymphnode metastases $(54.8\%\;vs\;12.2\%)$ (p<0.005). Surgical salvage rate w8s 4/7 $(57\%)$. Three patients developed distant metastases. Major complications requiring surgery were seen in $11\%$, Radiation therapy alone with surgical salvage was an effective, voice preserving treatment for stage I, II and selected III carcinoma of the supraglottic carcinoma, however planned combined treatment with surgery and radiation therapy is advised for stage III and IV carcinoma of the supraglottic larynx with resectable neck disease.

Even though maxillary cancer is usually discovered in advanced stage, its regional lymph node or distant metastases are not common comparing to other head and neck cancer. So the result of treatment depends upon local control of the tumor. Because maxillary sinus is anatomically located adjacent to orbit and skull base, it is difficult to remove the tumor completely with sufficient safety margin like in other malignant tumor. Traditionally, surgery including aggressive resection, radiotherapy or both combined therapy have been widely accepted in many institutes, but their results are not still satisfactory. Sixteen cases of maxillary cancer( all squamous cancer, T2 1 case, T3 6 cases, T4 9 cases, mean age 57.2 years) were treated by intraarterial chemotherapy, raditherapy and surgery and followed up retrospectively. 5 year survival rate by Kaplan-Meier method was 51.95%, and orbit, palate or cheek skin could be preserved in many cases and their functional result was good.

Fifty seven patients with differentiated thyroid carcinoma were performed radioactive iodine-131 whole body scans after administration of diagnostic dose $(2\sim10\;mCi)$ and therapeutic dose $(30\sim150\;mCi)$ within three months. We evaluated the state of radioactive iodine-131 uptakes in whole body scan to detect correct metastasis of thyroid carcinoma. The results are as follows: 1) In 20 of the 57 patients (35%), the therapeutic scan showed the additional uptakes that were not seen in the diagnostic scan. 2) In 9 (64.2%) of the 14 patients who had been received the thyroid ablation theraphy with I-131 previously, new additional lesions were found in the therapeutic scan but only 11 (25%) of the 32 patients who had not been received the thyroid ablation theraphy disclosed new uptake lesions (p < 0.01). 3) The additional uptake lesions of therapeutic scan were significantly more common in the bony metastatic foci (55.7%) than other areas (p < 0.01). In 11 (55%) of 20 patients, additional uptake regions were anterior neck areas (thyroid bed or regional lymph node). We conclude that diagnostic scan with $2\sim5$ mCi I-131 is inadequate in evaluating residual iodine avid tissues of patients with thyroid carcinoma. Also post-theraphy I-131 whole body scan would be important to evaluate the correct staging and prognosis of thyroid carcinoma, and to follow-up patients.

Squamous cell carcinoma (SCC) of the retromolar trigone (RMT) is a rare but potentially fatal disease that carries a poor prognosis due to its unique anatomic position. RMT SCCs tend to spread to vital nearby structures, including the tonsillar pillar, masticatory muscles, and underlying mandibular bone, even in their early stages, and aggressive treatment is often warranted. This systematic review appraises and qualitatively analyzes all available literature regarding the survival outcomes and prognosis of RMT SCC. Four databases were searched to identify all eligible articles published since January 1980. Of the 1,248 studies, a total of 15 studies representing 4,838 cases met the inclusion criteria. The evaluated patients had a high rate of advanced tumor stage (T3 or T4: 61.4%), lymph node metastasis (38.8%), and mandibular bone invasion (24%) at the time of diagnosis. Aggressive surgical treatments such as lip-splitting (92%), segmental mandibulectomy (61.1%), radical neck dissection (44.1%), and reconstruction using free flaps (49.5%) was undertaken for 92% of the pooled patient population. The mean rates for local, regional, and systemic recurrence were 23.40%, 8.40%, and 8.50%, respectively. The mean 5-year overall survival rate was 38.90%. Osteonecrosis was noted in 11.6% of the 328 patients who received radiotherapy. In conclusion, RMT SCC is generally associated with high recurrence, low survival, and high postoperative complication rates. Early diagnosis and aggressive treatment are thus warranted. However, significant methodological problems hamper current knowledge. Future studies of this topic that use randomized or cohort designs are thus needed.

A retrospective analysis was performed to assess the relationship between the treatment modalities and treatment results in patients with adenoid cystic carcinoma of the maxillary sinus. From Feb. 1977 to March 1994, 10 patients with the disease were treated at the Department of Radiation Oncology, Yonsei Cancer Center, Yonsei University College of Medicine. Six men and 4 women were presented with median age of 57 years. According to AJCC TNM system, all patients except one had advanced T3 and T4 disease. Only one patient had the regional metastasis to lymph node but none of them had hematogenous metastasis on initial admission. One patient(Group 1) was treated with surgery alone, 3 patients(Group 2) were treated with definitive radiotherapy and 6 patients(Group 3) were treated with combination of surgery and radiotherapy. One patient who was treated with surgery alone had experienced a locoregional recurrence 9 months later and 3 patients who were treated with radiation therapy alone had PRs(partial response) followed by the subsequent progression of the local disease. Whereas all patients who were treated with combination of surgery and radiation therapy had CRs(complete response). Among them, only one patient was recurred in the primary site, who was salvaged by reoperation and reirradiation therapy. In conclusion, combination of surgery and radiotherapy resulted in the best treatment modality for adenoid cystic carcinoma of the maxillary sinus. Improved radiotherapy technique and development of multimodality treatment are needed to improve the local control and the survival rate in patients with advanced adenoid cystic carcinoma of the maxillary sinus.
