식도의 원발성 소세포암은 매우 드문 형태의 식도암이며, 위험한 예후를 동반한 극히 불량한 종양이다. 이런 악성적인 가능성으로 인하여 소세포암의 치료는 일반적으로 항암치료가 우선이다. 우리는 식도하부에 발생한 소세포암 환자 1례를 경 험하였다. 환자는 53세된 남자였으며, 진단 당시 국소적 임파절전이가 있었고, 완전 절제와 항암치료를 받았다.

Metastatic thyroid carcinoma in bone shows characteristic expansile, trabeculated lysis on radio-gram. The ordinary scintigraphy manifests with a simple photopenic defect. We were able to portray trabeculation within photopenic defects. We present papillary thyroid carcinoma and follicular thyroid carcinoma, one each, pinhole bone scintigraphic findings of which are cold area with septated increased uptake at the iliae bone. These findings correspond very well with their X-ray pictures.

기관지에서 발생한 점막표피양 종양은 매우 드물게 발생하는 종양으로 특히 국내에서 13세 이하 소아에서는 아직 보고된 바가 없다. 대개는 기관지 폐쇄에 의한 증상으로 발견되어 흔히 결핵으로 오인되기도 한다. 종양의 악성여부와 원위부 전이가 흔치 않아 수술적 완전 절제가 치료 원칙이며 예후는 조직학적 분류에 의해 결정된다. 본원에서는 기침과 열을 주소로 한 10세 남아에서 기관지 내시경을 통한 생검과 개흉술 통한 우 중, 하엽절제술을 시행하여 성공적으로 종양을 제거하였기에 여러 문헌 고찰과 더불어 보고하는 바이다.

Synovial sarcoma is commonly found in the extremities of mesenchymal origin, but rare in the head and neck area. Histopathology is diagnostic and it shows a biphasic pattern with two neoplastic elements; spindle cell, sarcoma like stroma and gland like clefts lined by epitheloid cells. Synovial sarcoma is high-grade neoplasm that expresses epithelial as well as supporting features. This paper presents a case of synovial sarcoma of hypopharynx on 25 years old male. He was treated by surgical excision and postoperative chemoradiotherapy. There were no evidences of local recurrence & distant metastasis for 19 months postoperatively.

Angiosarcoma of the brain, either primary or metastatic is extremely rare. Moreover, angiosarcoma metastazing to the brain is also highly unlike to occur when comparing with metastases to the other organs. Thus, an ideal treatment strategy has not been established. A 67-year-old man with past surgical history of a scalp angiosarcoma underwent surgical resection of intracranial invasion. Because of wide scalp flap excision and resultant poor vascularity of the scalp flap, additional radiation was not provided. Because adjuvant therapy is impossible due to poor scalp condition, more careful but ample resection of the primary lesion is essential to conduct initial operation.

Pancoast tumor was specific lung carcinoma that has been symptoms and signs according to locations. It was located in peripheral,and involved the extrathoracic structures more than parenchyme of the lung. At 1838, Hare reported it, and at 1932 Pancoast was first described it. Prior to 1950,superior sulcus tumor was considered uniformly fatal, but at 1961 Paulson and Shaw advocated the use of preoperative irradiation therapy and followed by an extended en bloc resection. Recently we were experienced 2 cases of pancoast tumor managed with same method. One was 60-years old man that has been recommended preoperative radiation therapy with dose of 3000 cGy to 20 fractions and followed resection after 4 weeks, the other was 53-years old man that has been recommended a dose of 4000 cGy to 20 fractions and followed resection after 4 weeks. On tumor histology first case was large cell carcinoma and second case was squamous cell carcinoma. all patients was complicated atelectasis. First patient was expired with brain metastasis after 17 months, second was expired after 6 months.

Adenoid cystic carcinoma is malignant neoplasm belonging to a group of tumors of salivary gland origin. It is an aggressive tumor characterized by slow growth and incidious destruction of surrounding tissues. Perineural invasion is a prominent feature. Spread to regional lymph node is rare, other than by direct extension. Distant metastasis are more common. We experienced a 65-year old female with adenoid cystic carcinoma of minor salivary gland in retromolar pad.

Mammary cancer is the most common malignant neoplasm in the bitch. It constitute 40 percent of all tumors in female dogs, which is three times higher than incidence of mammary tumors in humans[2]. Cytological differentiation between benign and malignant canine mammary tumors is difficult, however, an irregular chromatin pattern was reported to be a significant criterion for malignancy[1]. It can be estimated that approximately 30 percent of the surgically removed mammary tumors are malignant[4]. Malignant mammary tumors often have some degree of infiltrative/destructive growth into adjacent tissues and/or invasion of vessels. Malignant mammary tumors often metastasize into local lymph nodes and lungs, and less frequently into other organs[3]. Based on histological and cytological criteria, this case was diagnosed as tubulopapillary carcinoma of the mammary gland. (omitted)

Primary intimal sarcoma of the pulmonary artery is a rare disease and there has been no report of any case originating from the pulmonary valve. Recently we experienced a 62 year-old female patient who had a primary intimal sarcoma of the pulmonary valve with distal metastasis. She was brought to medical attention due to exertional dyspnea facial edema productive coughing and general weakness for 1 month. Chest CT and echocardi-ography suggest an acute pulmonary thromboembolism or tumor. Exploration showed a large polypoid mass arising from the pulmonary leaflets and multiple masses on distal pulmonary arteries. We replaced the pulmonary valve and reconstructed the pulmonary artery. She received radiotherapy 1 month postoperatively and now 4 months after surgery she has begun receiving chemotherapy.

Merkel cell carcinoma (MCC) is a relatively rare and aggressive cutaneous neuroendocrine malignancy. It is characterized by high rates of recurrence and metastasis, both to regional lymph nodes and to distant locations. Its characteristic clinical manifestation is a single, painless, hard, erythematous nodule on a sun-exposed area, particularly in older men. Surgical management of both the primary site and the sentinel lymph node is the standard of care. In this article, we describe the diagnosis and treatment of a case of MCC in the left cheek.
