Malignant peripheral nerve sheath tumor (MPNST) is an extremely rare sarcoma of soft tissue. It is locally invasive, frequently recurred and metastasizes distantly, therefore has a very poor prognosis. the most involved sites are human body and extremities, and MPNST occurs and involved very rarely in the parapharynx of neck. MPNST does not react to radiotherapy and chemotherapy, therefore complete surgical resection is the most important treatment. Since immunohistochemical staining is essential for the final diagnosis, it is common to be confirmed after surgery. We report a case of giant MPNST without symptom in the head and neck involving the right parapharynx with multiple distant metastases in a 74-year-old patient on a review of the literature.

The malignant peripheral nerve sheath tumor(MPNST) is an extremely rare soft tissue sarcoma of ectomesenchyme also known as malignant schwannoma or malignant neurilemoma. It is a highly malignant sarcoma, which is locally invasive, frequently leading to multiple recurrences and eventual metastatic spread. The peak incidence of this disease is known to arise in the seventh decades. In human body, trunk and extremities are the most commonly involved sites, and only 8-14% of all lesions appear in head and neck region. Because immunohistochemical staining is essential in final diagnosis. The authors report a case of malignant peripheral nerve sheath tumor in neck with hypopharyngeal cancer simultaneously on a review of the literature.

Primary malignant fibrous histiocytoma (MFH) of the chest wall is extremely rare and is characterized by aggressive features, including a high incidence of local recurrence and distant metastasis. Surgical resection of the chest wall is the primary modality of management. However, surgical treatment is not generally recommended in patients with evidence of distant metastasis. Here, we present a case of chest wall MFH along with a schwannoma mimicking distant metastasis in the right upper arm. The patient was treated by radical en bloc resection and survived for more than 9 years without recurrence.

Many patients with intractable chest pain visit pain clinics, two of which, with rare cases of an intraspinal tumor and malignant mesothelioma were experiences at our clinic. A 37-year old female patient presented with exacerbating chest pain, but without neurological manifestations, of 15-months duration. Her laboratory findings, such as blood tests, chest X-ray, EKG, abdominal ultrasonography and chest CT, were normal. MRI revealed an intradural extramedullary schwannoma at the T 5 and 6 levels of the thoracic spine. She completely recovered following a laminectomy, with removal of the tumor. The other case was a 65-year old male patient, who presented with chest and back pain in the thoracic area of 6 months duration. He had no cough and dyspnea, and was initially misdiagnosed with intercostal neuralgia; therefore, pain control medication was administered, but all trials were ineffective. Finally, chest CT revealed a malignant mesothelioma, with multiple spine metastases. In conclusion, patients with intractable chest pain should be re-examined both clinically and radiographically.

We experienced 1 year old female patient with partial anomalous pulmonary venous return of the right lung into the inferior vena cava with atrial septal defect. Total anomalous venous drainage from the right lung is an uncommon form of congenital defect, and it may or may not be associated with an atrial septal defect. One patient having this venous anomaly is presented with a detailed description of the surgical reconstruction used. The postoperative result has been satisfactory.

The malignant peripheral nerve sheath tumor is an extremely rare soft tissue sarcoma. It is a highly malignant sarcoma, which is locally invasive, frequently leading to multiple recurrences and eventual metastatic spread. The peak incidence of disease is known to occur sporadically between the age of 20s and 50s, and is usually associated with the neurofibromatosis type I. In human body, the trunk and extremities are the most commonly involved sites, with only 8-14% of all lesions appearing in the head and neck region. We present a case of malignant peripheral nerve sheath tumor involving the right parapharynx in a 48-year-old patient who complained of headaches in the right parietal area and of dysphagia that aggravated over a month. After surgery, tumor was finally diagnosed as malignant peripheral nerve sheath tumor by histopathologic examinations. The authors report a case of malignant peripheral nerve sheath tumor in the right parapharynx with a review of the literature.

견갑관절 주위의 악성종양 치료후의 기능평가를 위하여 저자들은 1991년 1월부터 1993년 12월까지 가톨릭대학교 의과대학 정형외과학 교실에서 견갑관절 주위 악성종양에 대한 수술적 치료를 받은 9례를 분석하여 다음과 같은 결과를 얻었다. 남자 5례, 여자4례이었고, 나이는 최저 22세, 최고 64세로 평균 47세이었다. 연부조직 종양이 2례(MFI, dermatofibrosarcoma protuberance 각각 1례)이었는데, 1례는 forequarter 절단, 1례는 광범위 절제술로 치료하였다. 골종양은 7례(chondrosarcoma 2례, osteosarcoma, MFH, plasmacytoma, thyroid carcinoma metastasis 및 malignant schwannoma 각각 1례)이었는데, 1례는 상완골 근위부 부분절제, 4례는 Malawer분류 제 I-A형의 절제, 1례는 제 I-B형, 1례는 제 V-B형의 절제술을 시행하였다. low grade의 연골육종 1례와 dermatofibrosarcoma protuberance 1례, 갑상선 종양 전이의 1례의 3례를 제외한 6례에서 항암화학요법, 혹은 방사선 요법을 시행하였으며, 1례에서 국소재발이 있었으나 평균 15.3개월 추시된 현재 전례가 생존하고 있다. 골종양 7례증 2례는 관절유합술, 4례는 관절전치환술로 치료하였으며, 관절유합술을 시행한 예와 관절성형술을 시행한 예의 기능은 큰 차이를 보이지 않았다.

기관 및 기관지 종양은 대부분이 악성 종양이며 양성 종양은 10% 이내에 불과하다. 특히 폐에 발생하는 원발성 신경성 종양은 전체 폐종양의 2% 이하로 대부분이 Schwann세포에서 기원한다고 알려져 있다. 이러한 종양은 주로 고립성 양성 종양으로 나타나며 드문 경우에 악성의 형태를 보이기도 한다. 기관지내 신경초종은 폐의 원발성 종양 중에서 발생빈도가 매우 낮은 것으로 알려져 있다. 저자들은 기관지내 신경초종으로 폐엽절제술을 시행한 2예를 보고하는 바이다.

Aspiration biopsy cytology is a convenient, easy and non-invasive method for diagnosis of tumors. The results and cytologic features of carcinoma in various organs have been reported frequently, however, those of soft tissue sarcoma are relatively rare to find. Here we describe fine needle aspiration cytologic features of various soft tissue sarcomas and discuss cytologic differential points. The material is 6 cases of soft tissue sarcoma that were confirmed by histologic examination. They are composed of 2 cases of dermatofibrosarcoma protuberans and one case of malignant fibrous histiocytoma, synovial sarcoma, alveolar soft pan sarcoma, and malignant schwannoma respectively.

상완 신경총에 발생하는 신경초종은 드문 질환으로 알려져 있다. 이들 중 악성 신경초종은 Schwan cell 또는 신경초 세포에서 기원한다. 빈도는 낮으나 Von Rechlinghausen's disease와 동반되기도 한다. 환자는 35세 여자로 약 10년 전 폐결핵의 과거력이 있었다. 1년 전부터 경부 종괴의 크기 증가가 있었고, 6개월 전부터 동통이 수반되었다. 종괴의 크기는 $5{\times}7cm$였다. 술 후 방사선 치료를 하였으나 2차례에 걸쳐 재발하여 흉곽 출구의 광범위 구역 절제술을 시행하였다.
