Although direct skeletal muscle invasion by carcinoma is well recognized, distant metastasis to skeletal muscle is uncommon. Furthermore, multifocal skeletal muscle metastasis is a very exceptional event. Some factors such as variable intra-muscular blood flow, mechanical factors including turbulent blood flow and muscle contraction, intra-muscular acidic condition, lactic acid, protease inhibitors in the extra-cellular matrix were proposed as causes of the rarity of distant metastasis to skeletal muscle. We report here a case of a 67 year old male who had multifocal skeletal muscle metastasis from the transitional cell carcinoma of left kidney.

From 1984 to 1988, fourty two patients with nasopharyngeal cancer were treated at the Department of Radiation Oncology in Kyungpook National University Hospital. Thirteen patients refused treatment and the median survival time was 7.8 months. Twenty nine patients received a full course of radiation at least 70 Gy to the primary site and 60 Gy to the nodal sites. These patients were all belonged to stage III or IV, The local control rate was $75\% in squamous cell carcinomas, and all the patients with lymphoepithelioma showed a complete response. Overall locoregional failure was $27.6\%. Distant metastasis was the predominant pattern of failures; 4/6 in lymphoepithelioma, 4/10 En squamous cell carcinoma. The Three-year-survival rate for squamous cell carcinoma was $40.5\%$, and for lymphoepithelioma $25.9\%, respectively. This may be due to the more frequent distant metastases in lymphoepithelioma and ineffective chemotherapy. No survival correlation was found with the level of neck node involvement. Though adjuvant chemotherapy was found to be of no benefit in overall survival, more prudent and aggressive chemotherapy would be necessary.

Between April 1982 and July 1991, 14 cases of squamous cell carcinoma of the extremities have been treated at the Department of Orthopedic Surgery, College of Medicine, Hanyang University. The diagnosis was made by clinical symptoms, history, tissue and lymph node biopsy. Age distribution was variable and the average age was 50.2 years old. The frequency was higher in male than female. The most common location arising the carcinoma was lower extremities. The most common etiology of carcinoma was chronic osteomyelitis, then chronic ulcers, burn scars in order. The average duration of illness was 22.8 years. The common clinical manifestations at the time of admission were chronic ulcer, growing mass, draining sinus in order. The choice of treatment consisted of early adequate amputation or radical resection of the focus and irradiation or chemotherapy.

Purpose: The purpose of this study is to compare general survival rate and survival rate according to expectable prognostic factors by analyzing the result of treating a patient of squamous cell carcinoma. Materials and Methods: From Mar. 1999 to Feb. 2011, 151 patients were pathologically confirmed as squamous cell carcinoma of limbs and body in our hospital, and among those patients, 51 patients underwent the surgical treatment. This study included 41 patients who underwent the surgical treatment and were followed-up for more than 12 months. The mean age of population was 64.4 years. 31 males and 10 females were included. Wide excision with following skin grafts or flaps for reconstruction (29 cases) was mostly performed, but amputation (12 cases) was also performed for cases with extremities where resection margin was difficult to obtain and cases with neural or vascular invasion. 8 patients underwent chemotherapy or radiotherapy after resection, and 33 underwent the operation only. Stages were classified by AJCC Classification, survival rate was calculated by Kaplan-Meier method and survival rate of groups was compared by Log-rank test. For the expectable prognostic factors related to survival rate, location of primary lesion, cause of disease, pathologic grade, staging, surgical method, additional anticancer therapy were examined and each survival rate was compared. Results: The average follow-up period was 65.2 (12-132) months. Thirty patients survived out of 41 patients till last follow up. The overall survival rate in 5 years was 77%. Three cases (7.3%) had local recurrence, and 7 cases (17.0%) had metastasis. The average period of recurrence from operation was 27 (18-43) months. Possible prognostic factors such as location of primary lesion, cause of disease, pathologic grade, staging, additional anticancer therapy showed no significant difference in survival rates. However, patients with amputation showed significantly lower survival rate than those with wide excision. Conclusion: In analysis the results of treating 41 cases of squamous cell carcinoma, the overall 5-year survival rate was 77%. And, among the several prognostic factors, only the surgical method was significant statistically.

It has been reported that p53 regulates the G2-M checkpoint transition through cyclin Bl, and it has been suggested that p53 plays an important role in the development and progression of various malignancies. The aim of this study is to clarify the role of the cell cycle regulators, cyclin B1 and p53 in patients with esophageal squamous cell carcinoma (ESCC). Material and Method: Tissue samples from 46 patients with ESCC were included in this study. Expression levels of cyclin Bl and p53 in samples of normal squamous epithelium, dysplasia, and tumor cells from patients with ESCC were analyzed by immunohistochemical study Result: Several cells in the basement layer of normal epithelium expressed cyclin B1. The number of cyclin B1 positive cells tended to increase as the degree of dysplasia increased from low grade to high grade. More than 10% of tumor cells were cyclin B1 positive in 19 patients (41.3%). Several clinicopathologic parameters, including tumor stage (p<0.05), pathologic Iymph node status (p<0.05) and invasion of Iymphatic vessels (p<0.05), were correlated with the overexpression of cyclin B1. Elevated expression levels of cyclin B1 also correlated with a poor prognosis in patient with ESCC in univariate analysis (p<0.05) and multivariate analysis (p<0.05), In contrast, p53 expression exhibited significant correlation with the level of cyclin B1 expression, but was not associated with prognostic parameters in patients with ESCC. Conclusion: These findings suggest that cyclin B1 is involved in the pathogenesis of carcinoma of the esophagus and that elevated levels of cyclin B1 expression, but not p53 expression, may indicate a poor prognosis for patients with ESCC.

Colorectal carcinomas are extremely rare in childhood and adolescence; however, the colon is the most common site of a gastrointestinal carcinoma. Mucin secreting adenocarcinomas with signet ring formation is the most common type of colon cancer identified in children. An 11-year-old boy had abdominal pain and weight loss for three months, back pain and left thigh pain for two months, and hematochezia for four days. Colonoscopy showed an annular mass in the sigmoid colon and the histopathology revealed a signet ring cell carcinoma. A metastatic signet ring cell carcinoma was suspected from the findings of the bone scan, and confirmed later by a left scalp mass incisional biopsy and a bone marrow biopsy. We report a case of a metastatic signet ring cell carcinoma of the colon in a child.

The clinical staging system for laryngeal cancers is not sufficient for prognosticator due to different biologic characteristics and their microenvironment according to primary sites. For determining the prognosticators, the authors peformed immunohistochemical staining to EGFR, p53 protein, and pRB in 40 cases of surgically treated squamous cell carcinomas of larynx in our institute during the past 5 years. The results are as followings; 1. The positive expression rate of p53 protein and negative expression rate of pRB showed correlations with clinical parameters. 2. The three-year survival rate for p53 protein positive cases was worse than the p53 protein negative cases. 3. Expression rate of EGFR was not correlated with the clinical parameters. As a conclusion, expression rates of p53 protein and pRB not only reflect well the biologic behavior of laryngeal cancer, but correlate closely with the tumor factors. Therefore they may be useful as the prognosticator to predict the malignant potency of laryngeal squamous cell carcinomas.

Squamous carcinomas of the thyroid gland are extremely rare, and its clinical course is very aggressive. It has poor prognosis, similar to that of anaplastic carcinoma. These tumors are radioresistant and often rapidly fatal. It is considered to originate from the follicular epithelium at present. Recently, authors had experienced 63-years old female patient, proved to be primary squamous cell carcinoma of the thyroid. We report this patient with a review of a literature.

Malignancy in a chronic pressure sore is rare among Marjolin's ulcers. Carcinomas arising in pressure sores are highly aggressive and usually fatal. Although carcinomas in pressure sores are generally well-differentiated squamous carcinomas, they can show quite an aggressive course and do not respond either to chemotherapy or radiotherapy. The mortality rate is high despite wide surgical resection. Extensive surgical excisions with wide surgical margins are necessary and elective lymph node dissection should be considered for optimal therapy. We report a squamous carcinoma arising in a pressure sore. The related literature was reviewed.
