Purpose: Malignant melanoma of the lower extremity is well known to metastasize to the lymph nodes of the groin. However, in rare cases, the initial site of the nodal disease can be the popliteal fossa. As of yet, there has not been any report on cases with popliteal lymph node metastasis in Koreans. In the following report, authors would like to present two cases of popliteal node metastasis. Methods: A 60 - year - old male patient presented with nodular mass at his left sole. He had popliteal node metastasis detected on preoperative positron emission tomography(PET). Another 67 - year - old man presented with pigmented lesion at his right heel. He also had popliteal node metastasis detected on the MRI. They underwent wide excision of the primary lesion with popliteal node dissection. Results: In the first case, $2.5{\times}2.5cm$ sized metastatic melanoma in popliteal node was pathologically confirmed. There were no postoperative complications, and to date(18 months after the surgery), the patient is alive with no evidence of disease. In the second case, multiple(4) metastatic melanoma in popliteal nodes was confirmed. The patient is alive, but has had interferon therapy for liver metastasis. Conclusion: By increasing the use of lymphoscintigraphy or PET as a preoperative diagnostic work - up for metastasis, even popliteal node metastasis undetectable in a physical exam becomes detectable. When metastatic lymph node is found, node dissection is the standard of care. Therefore, it is essential that we know the anatomy and surgical technique for popliteal lymph node dissection.

Purpose: The incidence of skin cancer is increasing throughout the world including Asian countries such as Korea. Still there are only limited reports of the clinical features of skin cancer in Korea, especially in the fields of plastic surgery. This study is to demonstrate the recent clinical trends of skin cancer and the treatment of skin cancer in Korea by analyzing a single institution's experience. Methods: During a 11-year period, 370 patients visited our department for the excision of skin cancer. Data of the patients such as histopathologic diagnosis, primary site of the tumor, age and sex of the patient, operative methods were reviewed retrospectively. Results: We had 370 patients, 215 men and 155 women. The ages ranged from 10 to 95 years with a mean of 58.8 years. A total of 143 patients were diagnosed as basal cell carcinoma, while 100 were malignant melanoma, 80 were squamous cell carcinoma, 17 were dermatofibrosarcoma protuberans, and 30 were other miscellaneous skin cancers. Local flaps were the most frequently used reconstructive method after wide excision of the cancer, which was followed by primary closure, split-thickness skin graft, free flap and full-thickness skin graft. Conclusion: There was a gradual increase in the incidence of skin cancer after the year 2000. Basal cell carcinoma had the highest incidence which frequently involved the sun-exposed regions in the old ages. Malignant melanoma showed a relatively high incidence compared with other previous studies in Korea. The extremities were the most frequent location for malignant melanoma. Clinical features of other various skin cancers were also reported in this study. The reconstructive method highly depends on the primary site of the cancer, while local flaps were the mostly used operative technique.

Although the characteristic cytologic features of melanoma have been well described the diagnosis of metastatic melanoma by fine needle aspiration cytology (FNAC) may be difficult in the case of amelanotic melanoma and in the absence of awareness of clinical history. Furthermore, when the breast is the site of initial presentation, it could simulate a primary breast carcinoma leading to misdiagnosis. The recognition of metastatic malignant melanoma in FNAC material is essential to avoid an unnecessary mastectomy and to ensure appropriate chemotherapy. We experienced a case of metastatic melanoma of breast which presented as solitary breast mass in a 56-year-old woman. She had a history of surgical excision of right foot for melanoma one year ago. The cytologic smears were composed of noncohesive epithelioid cells with round or eccentric nuclei, bi-or multi-nucleation, prominent nucleoli, fine chromatin, and intranuclear inclusions. The cytoplasm of tumor cells had scanty melanin pigment but were diffusely positive for S-100 protein.

원발성 안구 흑색종은 20세 이상의 성인에서 가장 많이 발생되는 안주의 악성종양이지만 한국에서의 발생빈도는 그리 흔하지 않은 것으로 되어 있다. 안구 흑색종의 치료전에는 문진, 이학적검사, 기본적인 혈액상검사와, 특히 간, 폐, 골에 세심한 주의를 하여야 하며, 그래서 흉부 X-선과 LDH, SGPT, Transpeptidase를 포함한 간기능 검사 등을 시행하여야 하고 만약 임상적으로 증상이 있거나 위의 검사상 비정상적인 소견을 보일 매에는 전신뼈 스캔, 간-지 라 스캔을 시행하여야 한다. 일반적으로 악성 흑색종은 방사선 치료에 대해 치료효과가 나쁜 것으로 알려져 있지만 때로는 총 종양조사선량 $7,000\~8,000 cG/8\~9$주로 매우 빠른 종괴의 감소를 보여 주기도 한다. 그리하여 저자등은 외부방사선조사로 빠른 치료반응을 보인 원발성 안주 흑색종의 치료와 문헌고찰을 보고하는 바이다.

Melanoma of the mucous membrane is a rare condition and has the worse prognosis than that of any other sites. It is usually asymptomatic in early stage and difficult to find out the primary lesion by visual examination, and these facts lead to delay in diagnosis and reduce the curability. The major factor of failure in treatment of melanoma is local recurrence rather than regional spread. Because the radical procedure is difficult in head and neck lesion due to anatomical limitation, radiation therapy and chemotherapy can be used in the treatment of local recurrence. We experienced two cases of nasopharyngeal melanoma in advanced stage and treated them with radiation therapy and/or chemotherapy. And both patients showed relatively favorable response to these palliative treatments.

Background: Metastatic cancer with invasion of skin, soft tissue and skeletal muscle is not common. Examples presenting as soft tissue masses could sometimes lead to misdiagnosis with delayed or inappropriate management. The purpose of current study was to investigate clinical characteristics in the involvement of metastatic cancer. Materials and Methods: A total of 1,097 patients complaining of skin or soft tissue masses and/or lesions were retrospectively reviewed from January 2012 to June 2013. Tumors involving skin, soft tissue and skeletal muscle of head and neck, chest wall, abdominal wall, pelvic region, back, upper and lower extremities were included in the study. Results: Fifty-seven (5.2%) patients were recognized as having malignancies on histopathological examination. The most common involvement of malignancy was basal cell carcinoma, followed by cutaneous squamous cell carcinoma, sarcoma and melanoma. The most common anatomical location in skin and soft tissue malignancies was head and neck (52.6% of the malignancies). Four (0.36%) of the malignant group were identified as metastatic cancer with the primary cancer source from lung, liver and tonsil and the most common site was upper extremities. One of them unexpectedly expired during the operation of metastatic tumor excision at the scalp. Conclusions: Discrimination between benign and malignant soft tissue tumors is crucial. Performance of imaging study could assist in the differential diagnosis and the pre-operative risk evaluation of metastatic tumors involving skin, soft tissue and skeletal muscle.

The melanoma differentiation-associated gene-7 (MDA-7) protein, also known as interleukin-24 (IL-24), is a novel candidate of tumor suppressor that can induce apoptosis experimentally in a variety of human malignant cells. However, there have been few studies about its role in colorectal cancer. We performed immunohistochemical detection of MDA-7/IL-24 in 399 tissue samples from primary colorectal adenocarcinoma patients using a tissue microarray. Western blotting was then done to confirm the immunohistochemical observations. MDA-7/IL-24 immunoreactivity was observed in 116 (29.1%) of the 399 colorectal adenocarcinoma cases. Analysis of the MDA-7/IL-24 expression by Western blotting confirmed the immunohistochemical results. The tumors with a negative MDA-7/IL-24 expression more frequently showed poor differentiation (P=0004), lymph node metastasis (P=0.001), deep invasion (P=0.008) and high stage (P=0.001). A subset of colorectal adenocarcinoma revealed a decreased expression of MDA-7/IL-24, and this was associated with progressive pathologic features. These findings suggest that loss of MDA-7/IL-24 expression may play a role in tumor growth and progression of colorectal adenocarcinomas.
