Purpose : To determine if the tumor intersitial fluid pressure (TIFP) and/or its change in patients with metastatic Iymph node in head and neck area can predict radiotherapy outcome. Materials and Methods : In 26 biopsy Proven metastatic Iymph node Patients in head and neck area with accessible by direct inspection and palpation, and of sufficient thickness (>1 cm) to permit accurate needle placement, we measured TIFP at cervical Iymph node before and during radiotherapy. Tumor size was measured clinically and radiologically. Results : The mean preradiotherapy TIFP was 24.7 mmHg. Preradiotherapy TIFP had marginally significant relationship with tumor size (p=0.06). Preradiotherapy TIFP significantly decreased when tumor size decreased (p=0.009). Preradiotherapy TIFP was not different between complete response group and group with partial or less response (p=0.75). Radiotherapy outcome was not different between group with above and group with below than average TIFP (p=0.229). TIFP decreased 36mmHg in complete response group and 29.7 mmHg in group with partial or less response. Conclusion :The mean TIFP was elevated with 24.7 mmHg. Preradiotherapy TIFP had marginally significant relationship with tumor size (p=0.06). TIFP decreased 36 mmHg in complete response group and 29.7 mmHg in group with partial or less respone but there was no statistically significant relationship in two groups.

Although an association of Kawasaki disease (KD) with infectious agents has been suggested, none have been proven to cause KD. In this case study, we present a case of KD with concurrent onset of influenza and Mycoplasma pneumoniae (MP) infections. A 27-month-old boy presented with prolonged fever, cough, and rhinorrhea. During the initial testing, influenza A infection was identified, and he was treated with oseltamivir. Despite the antiviral therapy, the fever persisted, and he had cervical lymph node enlargement, bilateral conjunctival injection, fissured red lips, strawberry tongue, and erythematous skin lesions on the Bacillus Calmette-$Gu{\acute{e}}rin$ vaccination site. Thus, the patient was diagnosed with KD and was treated with intravenous immunoglobulin (IVIG). The result of the initial antimycoplasma immunoglobulin M (IgM) antibody testing and was positive, and an increased IgM titer from baseline was found in a repeat test. We reviewed the hypotheses on pathogens known to be associated with KD and the etiology of KD. Based on our findings, we suspect that symptoms of KD and coronary artery lesions can occur from various infections besides those caused by Mycoplasma species and influenza viruses.

In spite of recent progress in anticancer chemotherapy, the survival of patients with metastases to the lung treated nonsurgically has been extremely poor. So we adopted more aggressive surgical approaches for the treatment of patients with pulmonary metastases since 1985. We experienced 22 operations of metastatic lung cancer in 19 patients in the department of Thoracic & Cardiovascular Surgery in Kosin Medical College since 1985, so we reviewed the results of treatment retrospectively. The results were as follows: 1. The primary organs of metastatic lung cancer were 4 cases in each of the breast, uterus, and extremities, 3 cases in the rectum, 2 cases in the kidney, 1 case in each of the pelvis and liver, and the pathological findings were 13 cases in carcinoma and 6 cases in sarcoma. 2. The treatments for primary lesions were 15 cases of the operations with anticancer chemotherapy or radiation therapy, 2 cases of choriocarcinoma with anticancer chemotherapy only, 1 cases of uterine cervical carcinoma with chemo-radiation therapy, and 1 case of pelvic synovia sarcoma with intra-arterial anticancer chemotherapy. 3. Disease free intrerval were as follows: 7 cases were in 2 years to 4 years, 4 cases were in 1 year to 2 years, and 5 cases were beyond one year, of them one case was discovered primary lesion and metastatic lung tumor concomittently. 3 cases were above 4 years, of them one case of breast cancer were above 13 years especially. 4. The sites of metastatic lung cancer was 15 lesions in the right lung, and 9 lesions in the left lung, And the lobar sites were 10 lesions in the upper lobe, 2 lesions in the middle lobe, and 12 lesions in the lower lobe. 5. The operative methods of metastatic lung cancer were 7 case of partial resection of lung, 12 cases of pulmonary lobectomy, 1 case of pneumonectomy and 1 case of dissection of mediastinal lymph node. 6. The postoperative complications were 1 case of mild respiratory insufficency, 1 cases of pyothorax, and 1 case of urethral stricture. 7. Postoperative adjuvant therapy were as follows: No adjuvant therapy were 4 cases, anti-cancer chemotherapy were 8 cases, radiation therapy was 1 case, and combined with chemo k radiation therapy were 8 cases. 8. The results of long term follow-up were as follows: The 5 patients were died at 2 months, 22 months, 24 months, 32 months, and 49 months postoperatively, so mean survival period was 32 months postoperatively excluding one patient who was died at 2 months postoperatively. And 14 patients are aliving, of them 3 patients are living in recurred state, and the other 11 patients are living without any evidence of recurrence.

Purpose : Kikuchi-Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis (HNL), is a self-limited disease characterized by cervical lymphadenopathy and fever. The etiology of KFD remains unknown; however, the self-limiting nature of HNL suggests the cause of this disease could be viral infection. For this reason, several viruses have been evaluated as possible etiologies of HNL, including Epstein-Barr virus (EBV), human herpesvirus 6 (HHV6), human herpesvirus 8 (HHV8), and cytomegalovirus (CMV). The aim of this study was to examine the relationship of EBV and HHV6 to HNL. Methods : Data pertaining to 51 cases with biopsy-confirmed HNL were collected between January 1999 and December 2005, from the Department of Pathology, College of Medicine, Pusan National University, Busan, Korea. The clinical records-including data regarding age, gender, duration of fever, and lymph node involvementwere reviewed retrospectively. The in situ hybridization (ISH) assay was performed by EBER PNA probe (Dako, Capinteria, CA, USA), and immunohistochemistry testing was performed with anti-HHV type 6 monoclonal antibodies (Chemicon, Temecula, CA, USA). Results : The HNL patients in this study were 24 males and 27 females, ranging in age from seven to 61 years (median: 25.9). ISH for EBV was positive in 8/51 (15.7%) biopsies, and immunohistochemistry for HHV6 was positive in 15/51 (29.4%) biopsies. Serologic analysis of EBV IgM was performed in 23 cases; only one patient was positive for EBV IgM and EBV ISH. Conclusion : Our study could not provide supportive evidence of a viral pathogenesis for HNL; therefore, cases of HNL may not have a dominant viral cause. However, some rare exceptional cases may have been caused by viral infection.

Objectives: Expression of HMGI(Y), a nucleoprotein that binds to A/T rich sequences in the minor groove of the DNA helix, is observed in neoplastically transformed cells but not in normal cells. We have analyzed HMGI(Y), p53 expression and Ki-67 labelling index in squamous cell carcinomas of the head and neck, and evaluated its clinicopathologic significance. Materials and Methods: 40 cases of squamous cell carcinoma of the head and neck were entered on the study of immunohistochemical stains for HMGI(Y), p53 and Ki-67. We analyzed the relationship between HMGI(Y), p53, Ki-67 expression and age, sex, primary tumor site, stage, survival rate, recurrence. Results: HMGI(Y) expression evidenced by immunohistochemical staining was observed in 35 of 40 (87.5%) squamous cell carcinoma of the head and neck. But no significant correlation was observed between HMGI(Y) expression and other clinical factors such as primary site, tumor stage, differenciation, cervical lymph node, metastasis, recurrence and immunohistochemical status of p53. The Ki-67 labelling index was significantly correlated with recurrence and HMGI(Y) expression (p<0.05). Conclusion: This results suggest the Ki-67 is a good prognostic factor and the HMGI(Y) expression plays some roles in carcinogenesis and cellular proliferation of squamous cell carcinoma of the head and neck. HMGI(Y) gene can be used as a cancer marker, the correlation between the gene expression and the prognosis of the cancer patient should be proved in the future studies.

Objectives: We'd like to give help in diagnosis and treatment of children's thyoid tumor through our clinical experiences and reference consideration. Materials and Methods: The authors report their experiences with 33 cases of thyroid tumor in patients younger than 16 years of age who were treated at Presbyterian Medical Center from 1979 to 1995. Results: 1) Girls were more predominant than boys by a ratio of 5.6:1. The peak incidence was in the 15 years old of age. 2) The final diagnosis in the 33 patients were thyroid carcinoma in 12 cases, nodular goiter in 6 cases, adenoma in 6 cases, Graves disease in 4 cases, Hasimoto's disease in 4 cases and cyst in 1 case. 3) All of 12 patients with thyroid cancer had nodular tumor. 4) In 5 of 6 patients with palpable cervical lymphadenopathy, the final diagnosis was thyroid carcinoma. 5) Delayed diagnosis arose in 6 of 12 thyroid carcinomas which were treated for long periods as benign disease. 6) The surgical procedures were total thyroidectomy in 3 cases, subtotal thyroidectomy in 13 cases and thyroid lobectomy in 17 cases. 7) 11 of 12 patients with thyroid carcinoma had subtotal or total thyroidectomy with lymphnode dissection and only one had lobectomy. 8) The overall rate of postoperative complication was 3%(1 of 33 patient). 9) Postoperative $^{131}I$ therapy was done in 7 case because of recurrence and distant metastasis in six and severe local invasion in one. 10) In thyroid cancer, the metastatic rate of lymph node at initial surgery was 81%(9/11) and rate of recurrence was 50%(6/12). 11) Patients with thyroid carcinoma were followed up for a mean of 12 years but only one died as a result of thyroid carcinoma 3.5 years later. Conclusion: The authors suggest that thyroid tumors in childhood should receive the benifit of joint management by endocrine pediatrician and experianced surgeons with an agreed protocol of diagnosis and management. We, also, recommend aggressive surgical and $^{131}I$ treatment as the most effective regimen for children with thyroid carcinoma.

Background: About 3% of all cancer patients suffer from cancer of unknown primary origin. Generally, carcinoma of unknown primary (CUP) carries a grave prognosis, but primary tumor presented to the neck is exception to this. The aims of study are to determine the role of chemotherapy and to find the prognostic factors in unknown primary tumor presented to the neck. Method and Material: Eighty-four patients were diagnosed with unknown primary tumor presented to the neck between January 1996 and June 2002. Among 84 patients, 43 patients (52%) received chemotherapy, radiation or surgery were performed in 20 patients (23%), 21 patients (25%) had no treatment. Results: The response rates to chemotherapy were 87.5% in CUP only localized to the neck and 44.0% in CUP systemically involved (p=0.012). A median follow-up duration was 6.4 years and overall median survival time was 9 months. The median overall survival time of patients treated with chemotherapy were 17 months and that of patients who received surgery or radiation were 20 months (p=0.3548). The important prognostic factors were performance status and the number of involved organ. Conclusion: The prognosis of patients with CUP presented to the neck is more favorable than that of patients with CUP of other localization. The effectiveness of chemotherapy for CUP only localized to the neck was similar to that of surgery or radiation. The important prognostic factors were performance status and the number of involved organ.

Kikuchi-Fujimoto disease was initially described as a self-limiting histiocytic necrotizing lymphadenitis in Japan in 1972, and is predominantly observed in women under the age of 30 year and in Asian populations. The pathogenesis is still poorly understood but is thought to include infections, and autoimmune and neoplastic diseases. The most common clinical manifestations are fever and painless cervical lymphadenitis. Diagnosis is based on the histopathological findings, characterized by focal necrosis in the paracortical region with abundant karyorrhexis, aggregates of atypical mononuclear cells around the zone of necrosis, absence of neutrophils and plasma cells, and usually intact lymph node capsule. There is no specific therapy for the condition, and aseptic meningitis can occur as one of the complications. Here, we report the case of a patient with Kikuchi-Fujimoto disease accompanied with aseptic meningitis, which may be confused as a case of tuberculous meningitis and lymphadenitis.

Purpose: In oral tongue cancer, the degree of tumor invasion has a significant effect on the prognosis. We hypothesized that the destruction of extracelluar matrix and neovascularization are related to tumor infiltration mechanism. By studying the the tissues of early stage oral tongue cancer patients, we are intend to clarify the invasion related factors in oral tongue cancer. Material and Methods: To demonstrate the invasion process in early T-stage oral tongue cancer, the expressions of extracellular matrix destruction related molecules(MMP2, MMP9) and neovascularization related molecule(VEGF) were observed by immunohistochemical study. Also, immunohistochemical staining of CD31 was done for quantification of neovascularization. With the experiment showed above, we analyzed relationship between expression of each substances and tumor invasion depth, tumor free survival rates and cervical lymph node metastasis rate in early T-stage oral tongue cancer. Results: The expression rates of MMP2, MMP9, VEGF in 38 early oral cancer patients were 52.6%, 78.9% 52.6%, respectively. Significant correlation was found between the VEGF expression and microvessel density showed by CD31 immunohistochemical staining(p<0.001). VEGF expressions were significantly related with tumor invasion depth(p=0.002). The tumor free survival rate of those patients with VEGF-positive tumors was significantly poorer than in those with VEGF-negative tumors(p=0.019). Conclusion: This results indicate that VEGF is a useful marker for predicting the tumor invasion in patients with early tongue cancer and could be used as a beneficial factors in defining operative field and prognosis.

Purpose : This study was Performed to identify the histopathologic feature by the reevaluation of the Pathologic specimen of the cervical tumors and to evaluate the clinical findings and the treatment results of the patients with small cell carcinoma of the cervix treated by radiotherapy. Materials and Methods : 2890 patients with cervical carcinoma received radiotherapy at the Department of Radiation Oncology. Yonsei Cancer Center, Yonsei University College of Medicine between October 1981 and April 1995. Of the 2890 patients in this data base, sixty were found to have small cell carcinomas $(2.08\%)$. Among them thirty six patients were transferred from other hospitals. the biopsy specimens of those Patients were not available. So we could review the slides of the other twenty four patients who were diagnosed at our hospital. Twenty four patients with small cell carcinoma of the cervix were analyzed retrospectively based on the assessment of H & E staining and other four immunohistochemical stains for neuroendocrine differentiation (neuron specific enolase, chromogranin. synaptophysin and Grimelius stain). And we also evaluate the Patients and tumor characteristics. response to radiation. patterns of failures, 5 year overall and disease free survival rates. Results : Thirteen tumors were neuroendocrine carcinomas(13/24 = $54.2\%$) and eleven tumors were squamous carcinomas, small cell type (11/24 = $47.8\%$) based on the assessment of H & E staining and other four neuroendocrine marker studies. So we classified the Patients two groups as neuroendocrine carcinoma and small cell type of squamous carcinoma, Among the 13 neuroendocrine carcinomas, five were well to moderately differentiated tumors and the other eight were Poorly differentiated or undifferentiated ones. The median age was 54 years old (range 23-79 years). Eight Patients had FIGO stage IB disease, 12 had stage 11, 3 had stage III and one had stage IV disease, Pelvic lymph node metastases were found in five Patients $(20.8\%)$. three of them were diagnosed by surgical histologic examination and the other two were diagnosed by CT scan. There was no difference between two histopathologic groups in terms of patients and tumor characteristics. response to radiation. 5 year overall and disease free survival rates. However the distant metastases rate was higher in neuroendocrine carcinoma Patients (6/13:$46.2\%$) than in small cell type of squamous carcinoma Patients (2/11:$18.2\%$), but there was no statistically significant difference because of the small number of patients (P>0.05). Conclusion : More than half of the small cell carcinoma of the cervix patients were neuroendocrine carcinoma (13/24 : $54.1\%$) by reevaluation of the biopsy specimen of the cervical tumors. The tendency of distant metastases of the neurolndocrine carcinoma was greater than those of the small cell type of squamous carcinoma $(46.2\%\;vs.\;18.2\%)$. But there were no differences in the patients and tumor characteristics and other clinical treatment results in both groups. These data suggest that radical local treatment such as radiotherapy or radical surgery combined with combination systemic cytotoxic chemotherapy might provide these patients with the best chance for cure.
