Purpose: Angiosarcoma of the scalp is unusual vascular tumor originating from endothelial cell. Angiosarcoma is an aggressive tumor with high propensity for both local recurrence and distant metastasis. We report 2 cases of angiosarcoma having poor prognosis recently. Methods: Case 1 was a 67 - year - old male patient. He visited the hospital with a $3{\times}5cm$ sized discolored mass in forehead. It began at one month ago from coming to the hospital. Case 2 was a 64 - year - old male patient. He visited for our hospital to remove a $4{\times}5cm$ sized scalp mass. He had a pruritis on scalp from 9 months ago before coming to the hospital. Despite of the conservative treatments, the wound was not healed and advanced necrotic lesion with hemorrhage. Results: Case 1 diagnosed as an angiosarcoma. He underwent a radical operation 5 times. But the tumor expanded multiple area in dura & frontal area of the brain. The patient rejected the treatment any more. And he died one month later. Case 2 diagnosed as an angiosarcoma and metastased to skull in MRI. He got a radical resection including cranium. Three months later, it recurred to ipsilateral Sternocleidomastoideus muscle. He got a additional operation & started radiotherapy. And now he is receiving chemotherapy, but the recurred lesion is expanding. Conclusion: Angiosarcoma is a highly malignant tumor. Especially it arises in vascularized area, it easily metastases. So it is the best to treat angiosarcoma with surgery included wide margins. Despite of the lesion is small, we remember that angiosarcoma is a tumor that consider to metastases.

A malignant sarcoma of soft tissue that arises near but not in a joint, most often in an adolescent or young adult, is typically slowgrowing, and may escapes notice until it causes pain. The diagnosis of this tumor can be suspected by X-ray or imaging, made by biopsy, and confirmed by chromosome studies. Cytogenic studies reveal a translocation between the X chromosome and chromosome 18 in the tumor cells. The most common treatment for the tumor is surgery to remove the entire tumor, nearby muscle, and lymph nodes. Synovial sarcoma tends to recur locally and to involve regional lymph nodes. Distant metastasis occurs in half cases. The well-documented and adequately followed cases are currently lacking and this report described an instance of Synovial sarcoma good result after treatment and review of literature.

The papillary carcinoma is the most common malignant neoplasm of thyroid gland and the prognosis is better than anyother type of thyroid carcinoma. However, the thyroid is closed to the important organs such as esophagus, trachea and larynx, there are some possibilities to invade these organs. In case of advanced disease, not only surrounding structures but also mediastinum and cervical lymphatic chain can be involved or distant metastasis develops frequently. Therefore in these cases the prognosis is worse and the rate of inoperable case is more than those of non-metastatic group. Generally, the treatment modality for papillary thyroid carcinoma consists of surgery, postoperative thyroid hormone and radioiodine therapy. If the tumor invades surrounding structures, cervical lymph node or mediastinum, total thyroidectomy and wide excision of tumor invaded area including mediastinal dissection and neck dissection is necessary. Recently, the authors have experienced a case of locally invasive and recurred papillary thyroid carcinoma without treatment for 7 years. The patient was performed previously thyroid lobectomy and isthmusectomy 13 years ago. We had determinded surgical therapy for this patient and performed mass excision with overlying skin, completion total thyroidectomy, right type I modified radical neck dissection, left lateral neck dissection, thoracotomy with supramediastinal dissection, shaving of diffusely involved trachea and skin defect reconstruction with pectoralis major myocutaneous flap. After operation 2 cycles of radioiodine therapy were taken. Now the patient is following up at the outpatient base and no evidence of disease state for postoperative 16 months. So we report on this case with a brief review of literature.

Management of traumatic skull base fractures and associated complications pose a unique reconstructive challenge. The goals of skull base reconstruction include structural support for the brain and orbit, separation of the central nervous system from the aerodigestive tract, volume to decrease dead space, and restoration of the three-dimensional appearance of the face and cranium with bone and soft tissues. An open bicoronal approach is the most commonly used technique for craniofacial disassembly of the bifrontal region, with evacuation of intracranial hemorrhage and dural repair performed prior to reconstruction. Depending on the defect size and underlying patient and operative factors, reconstruction may involve bony reconstruction using autografts, allografts, or prosthetics in addition to soft tissue reconstruction using vascularized local or distant tissues. The vast majority of traumatic anterior cranial fossa (ACF) injuries resulting in smaller defects of the cranial base itself can be successfully reconstructed using local pedicled pericranial or galeal flaps. Compared with historical nonvascularized ACF reconstructive options, vascularized reconstruction using pericranial and/or galeal flaps has decreased the rate of cerebrospinal fluid (CSF) leak from 25 to 6.5%. We review the existing literature on this uncommon entity and present our case series of n = 6 patients undergoing traumatic reconstruction of the ACF at an urban Level 1 trauma center from 2016 to 2018. There were no postoperative CSF leaks, mucoceles, episodes of meningitis, or deaths during the study follow-up period. In conclusion, use of pericranial, galeal, and free flaps, as indicated, can provide reliable and durable reconstruction of a wide variety of injuries.

식욕부진, 호흡부전, 또는 비출혈을 보이는 두 마리 개가 내원하였다. 신체검사에서 호흡곤란, 개구호흡 및 커다란 구개 종양을 확인하였다. 신체검사 중 2 번 증례에서 호흡부전으로 인한 심정지가 발생하였고 심폐소생술과 산소 공급을 통해 안정화 되었다. 1 번 증례의 CT 촬영에서 경구개 연구개를 포함하는 구강 인두, 인두 내 입구, 인후두 부위의 종양을 확인하였다. 연하곤란 및 호흡부전 개선을 위해 보호자 동의 하에 완화 수술을 결정하였다. 종양 제거 후 발생한 결손 부위 재건을 위해 구강 내 점막을 사용하여 회전 및 전진 피판술과 양측 90o 자리바꿈 피판술을 1 및 2 번 증례에 각각 적용하였다. 조직 검사 결과, 두 마리의 개 모두에서 무멜라닌 색소성 흑색종이 진단되었다. 수술 후 7 일째 두 마리 모두에서 정상 연하와 호흡이 확인되었다. 수술 후 4 주째 1 번 증례의 수술 부위에서 재발된 종양이 관찰되었다. 보호자가 추가적인 치료를 원하지 않았고, 연락 두절로 인하여 수술 후 2 개월 이후의 확인은 불가능하였다. 수술 후 3 주째 2 번 증례의 신체검사 및 방사선 촬영에서 국소적인 재발 및 전이는 확인 되지 않았다. 수술 후 7 주째 유선상으로 확인한 결과, 2 번 증례에서 원인불명의 갑작스러운 사망이 확인되었다.

목적: 악성 흑색종의 치료 중 가장 중요한 것은 외과적 전절제술이며, 수술시 광범위 절제술을 시행한다. 저자 등은 광범위절제와 면역화학요법을 시행한 후 각 병기별 5년 생존율을 알아보고 예후에 영향을 주는 요인을 주는 요인들을 분석하고자 한다. 대상 및 방법: 1995년 3월부터 2003년 8월까지 악성 흑색종으로 진단 받았던 35명(남자 17명, 여자 18명)을 대상으로 광범위절제술과 면역화학요법을 시행한 후 추시 관찰하였다. 절제술은 종양의 크기나 피부층의 침범정도와 상관없이 종양의 변연으로부터 2 cm으로 하였고, 절제술 후 덮이지 않는 피부 결손부는 피판 이식술이나 전층 피부 이식술을 이용하였다, 면역화학요법으로는 dacarbazine (DTIC) 400 mg과 인터페론-${\alpha}$ 300만 IU를 병용 투여 하는 방법을 사용하였다. 면역화학요법은 III기 이상의 환자에게 시행하였고, 병기는 2002년 개정된 AJCC 병기를 이용하여 판정하였다. 또 이들 환자들에 대해 국소재발과 국소전이, 그리고 원격전이여부를 조사하였고, 각 병기별 5년 생존율을 조사하였다. 결과: 발생부위는 족부가 15명(42.8%)으로 가장 많았고, 족관절부 5명(14.2%), 하퇴부 2명(5.7%), 대퇴부 2명(5.7%), 수부에 5명(14.2%)이었다. 병기별 발생빈도는 IA 8명(22.8%), IB 9명(25.7%), IIA 4명(11.4%), IIB 2명(5.7%), IIIA 1명(2.8%), IIIB 2명(5.7%), IIIC 2명(5.7%) 그리고 IV기는 7명(20.0%) 이었다. 각 병기별 5년 생존율은 I기에서 94.1%, II기에서 66.8%, III기에서 40%, IV기에서 14.3%로 나타났다. 결론: 악성 흑색종은 III기 이상에서는 5년 생존율이 낮았다. 악성 흑색종의 치료는 초기에 진단하여 병기에 따라 치료의 방법을 달리하므로 수술전 병기의 확인이 매우 중요하다. 광범위 절제연에 대해서는 종양 두께에 따라 1~3 cm의 절제연으로 광범위 절제를 권유한다.
