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.

Angiosarcoma is a rare malignant mesenchymal tumor of vascular or lymphatic origin and represents less than 1% of all malignant tumors. Radiation therapy is a standard treatment in many head and neck cancer cases, but ionizing radiation is associated with radiation carcinogenesis including radiation-induced angiosarcoma. In this article, we report a rare case of radiation-induced angiosarcoma found in a 58-year-old female patient who was previously diagnosed with an odontogenic keratocyst and mucoepidermoid carcinoma.

Breast angiosarcoma is a very rare manifestation. Herein, we report a case of breast angiosarcoma in a 21-year-old woman admitted to our hospital with a one-year history of a palpable mass with fullness and swelling of the right breast. The various imaging findings, including mammography, ultrasound (US), and magnetic resonance imaging (MRI), of this rare disease are described. The imaging findings of US and combined MRI of breast angiosarcoma were specific in this case. The imaging characteristics could be helpful in detecting and diagnosing breast angiosarcoma in young women with a palpable mass with fullness and swelling of the breast.

Purpose: Angiosarcoma is a rare malignant neoplasm of endothelial type cells that line vessel walls. It tends to occur in aged male and the prognosis of angiosarcoma is very poor because of frequent local recurrence and early metastasis. The treatment regimen is yet to be established from its rare occurrence but the wide excision in early stage is known to be the most effective. The authors report two cases of near totally excised angiosarcoma with more than a safety margin of 5 cm. Methods: The two subjects were aged male patients, one of the two was diagnosed with angiosarcoma from our institution confirmed by the biopsy. The other one went through the wide excision with a safety margin of 2 cm and split-thickness skin graft but local recurrence was observed. The two patients underwent near total excision with more than a safety margin of 5 cm, leaving only the periosteum. After confirming that the angiosarcoma had not infiltrated the excision margin, reconstruction with split-thickness skin graft was performed. Results: Based on 6 months and 24 months post-surgery assessment, no local recurrence or remote metastasis in the lungs, liver, bones, and lymph nodes at the neck, where remote metastasis is common, was reported by the two subjects who underwent near total excision with a safety margin of 5 cm. Conclusion: Angiosarcoma has very poor prognosis from its frequent recurrence and metastasis. To enhance the survival rate of angiosarcoma patients, early diagnosis, timely surgical treatment, and radiotherapy after surgery are critical. In addition, authors suggest that it is necessary to further study the efficacy of wide excision using a wider safety margin as much as possible, and to apply this to more cases.

Primary angiosarcoma of the breast is extremely rare and is observed in 0.0005% to 0.05% of primary breast tumor cases. The diagnosis of this tumor is difficult due to its undefined characteristics. Radiologic findings are often nonspecific and appear completely normal in one-third of patients with primary angiosarcomas. The prognosis is usually poor, and the treatment choices include mastectomy or wide excision. Radiotherapy and chemotherapy produce varying results. We report a patient with primary angiosarcoma of the breast to further our understanding of the characteristics of this tumor and facilitate the correct diagnosis of breast angiosarcoma.

Angiosarcoma is a rare and high aggressive malignant tumor originated from endothelial cell. Angiosarcoma has four clinical types that are in the scalp and face of old age, in chronic lymphedema, in previously irradiated sites, and malignant angioendothlioma. We report one case of angiosarcoma of the scalp in a 74-year-old male patient. The patient had $4.0{\times}4.5cm,\;4.0{\times}3.5cm$ sized, localized, asymmetric several dome-shaped nodule and plaque with crust and ulcer on the parieto-frontal area of the scalp. We performed wide excision and subsequently covered with split-thickness skin graft. Postoperatively the patient underwent radiotherapy for prevention of recurrence and he had been followed up for 1 year without evidence of recurrence.

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.

Angiosarcoma is a rare and highly malignant neoplasm which develops from the endothelium of blood vessels. A few cases of primary angiosarcoma of the parotid gland have been reported. However, there is no report of primary angiosarcoma of the accessory parotid gland. In this case, we report a primary angiosarcoma of the accessory parotid gland in a 45-year-old man with growing cheek mass. Ultrasonography revealed a $2.0{\times}2.6cm$ sized homogeneous hypoechoic mass and computed tomography showed a contrast enhanced homogeneous mass. Fine needle aspiration biopsy suggested a benign tumor. The mass was completely excised with a minimal vertical incision. The histopathology showed anastomosing vascular channels lined by atypical endothelial cells and many branching vessels with staghorn appearance with positive immunohistochemical staining for CD34, a highly specific endothelial marker. The patient underwent postoperative radiotherapy and was followed for 8 years without recurrence and metastasis.

혈관육종은 악성 연부 조직 종양 중 매우 드문 형태의 종양으로 그 중 만성 림프부종에 발생한 것을 Stewart-Treves syndrome이라 부르기도 한다. 이는 일반적으로 유방암의 치료로 행해지는 유방제거술 및 방사선 치료 후 상지의 장기간의 림프부종의 합병증으로 주로 발생되는 것으로 알려져 있으며 예후는 좋지 않은 것으로 보고하고 있다. 저자들은 17년 전 자궁암으로 자궁적출술을 받은 환자가 수술 후 발생한 장기간의 하지의 림프부종으로 인해 1년 전 타병원에서 대퇴부의 수술적인 치료를 받았으나 이 후 대퇴부의 혈관육종이 발생하여 광범위 절제술을 시행한 예를 경험하였기에 이를 문헌 고찰과 함께 보고하는 바이다.

Angiosarcoma of the bone is rare with an incidence of 0.13%. It may be solitary or multiple. Its cytologic findings by FNA have rarely been reported. We report a case of angiosarcoma of the rib in a 66 year-old man. FNA revealed single or clusters of round to oval shaped cells in a hemorrhagic and myxoid background. The large central nuclei had irregular nuclear membrane, chromatin clumping and prominent nucleoli. The cytoplasm was scanty with an eosinophilic distinct cytoplasmic border. Erythrophagocytosis by malignant cells was also found. Histopathologic examination confirmed the diagnosis of angiosarcoma revealing irregular and complex anastomosing vascular channels lined by malignant round tumor cells, protruding into the lumen. Immunohistochemical staining revealed diffuse strong positive reaction to factor VIII-related antigen and CD31.
