  • Angiosarcoma of the breast is a rare malignant sarcoma of endovascular origin that presents with various radiological findings. We encountered a case of angiosarcoma of the breast presenting as an irregular indistinct hyperechoic mass on ultrasonography, with a large single angiosarcoma of the spleen in a previously healthy 36-year-old female. Herein, we report the imaging and pathologic findings and review the literature.

  • Telangiectatic osteosarcoma is a rare variant of osteosarcoma. The rib is an uncommon primary site for conventional osteosarcoma, and even more for telangiectatic osteosarcoma. Because this tumor consists of single to multiple cystic cavities that contain blood or necrotic tumor with no appreciable areas of sclerosis, careful observation is needed to differentiate this malignancy from other benign cystic lesion. Therefore primary differential diagnosis including telangiectatic osteosarcoma is important, although rib is not the predilection site of telangiectatic osteosarcoma. We present a case of telangiectatic osteosarcoma arising in a rib. We reviewed the literature concerning telangiectatic osteosarcomas and primary osteosarcomas arising from the rib. The differential diagnosis of telangiectatic osteosarcoma and clinical features of osteosarcomas arising from unusual locations were discussed.

  • Angiosarcoma is a malignant endothelial cell tumor of lymphatic or vascular origin and is most commonly found in the skin and soft tissue. Primary mesenteric angiosarcoma has rarely been reported. Here, we present a case of primary mesenteric angiosarcoma manifesting as a gradually enhancing mass along with necrosis and hemorrhage.

  • Epithelioid angiosarcoma is a rare variant of angiosarcoma characterized by an epithelioid morphology that mimics carcinoma. Therefore, multicentric epithelioid angiosarcoma is easily misdiagnosed as bone metastasis from carcinoma and has an aggressive clinical course. Here, we present a rare case of a 61-year-old male with multicentric epithelioid angiosarcoma of the bone. Plain radiography, CT, and MRI revealed multiple osteolytic lesions in both femurs; some lesions showed soft tissue extension with cortical bone destruction. Interestingly, PET-CT revealed that the lesions were only distributed along the bones of the lower extremities, including the pelvic bones, femurs, and tibiae. Despite histological analysis initially suggesting metastatic carcinoma, after additional immunohistological staining, including that for vascular markers (CD31 and ERG), the final diagnosis was epithelioid angiosarcoma. A better understanding of the clinicoradiological features of this disease may help eliminate diagnostic confusion and provide better management.

  • Colonic angiosarcoma is an extremely rare and aggressive malignant tumor with poor prognosis. We report a case of colonic epithelioid angiosarcoma with colonic obstruction and rapidly progressive hepatic metastasis in a 44-year-old female. Abdominal CT revealed a heterogeneously enhancing irregular mass in the ascending colon, causing proximal bowel distension. The patient underwent surgery, and histopathological examination revealed a poorly differentiated carcinoma. A follow-up liver dynamic MRI after 4 months revealed newly developed diffusely scattered numerous small nodules in both hepatic lobes with peripheral and nodular marked arterial hyperenhancement, raising the suspicion of hepatic angiosarcoma. A pathologic second opinion was obtained, and additional immunohistochemistry revealed colonic epithelioid angiosarcoma. The patient showed progressive hepatic metastasis on follow-up abdominal CT after 6 months and died 8 months after initial diagnosis. We describe an educational case of colonic angiosarcoma, a rare malignant tumor, with rapidly progressive hepatic metastasis that showed radiologic findings suggestive of angiosarcoma and enabled a re-diagnosis for proper treatment and prognosis prediction.

  • Primary pulmonary artery sarcoma is very rare disease. The diagnosis of pulmonary artery sarcoma is frequently confused with pulmonary embolism because its clinical symptom and radiologic findings are similar with pulmonary embolism. It was often diagnosed at autopsy as it progresses rapidly. So Pulmonary artery sarcoma must be suspected if the origin of thrombus is not known and anticoagulation therapy is not effective. In this case, a 57 years old man who has been diagnosed pulmonary embolism was transferred to our department because of ineffective anticoagulant therapy and its worsening lesion despite of 5 month-therapy. In operative findings, it was pulmonary artery sarcoma that invaded to pericardium. There was angiosarcoma in right pulmonary artery, which metastasized to lung parenchyme. Under cardiopulmonary bypass, we resected main pulmonary artery and right lung. The Gore-tex graft was interposed between main pulmonary artery and left pulmonary artery. He was discharged after chemotherapy.

  • Angiosarcoma is a very rare disease of soft tissue sarcoma, and angiosarcoma arising in a region of chronic lymphedema is referred to as Stewart-Treves syndrome. it typically occurs in postmastectomy lymphedema of the arm and sporadically in a lymphedematous leg. The prognosis, even with wide surgical excision and subsequent radiotherapy, is poor. The authors experienced a case of angiosarcoma in a chronically lymphedematous leg which had undergone hysterectomy due to cervical cancer 17 years ago and lymphedema of leg persists for about 16 years. We report a case of angiosarcoma with a brief review of the literature.

  • An 80 year-old male with a medical history of angiosarcoma of the scalp visited the Emergency Department complaining of dyspnea, and the chest X-ray revealed pneumothorax. He has undergone scalp resection and radiotherapy three years ago due to angiosarcoma. Due to a persistent air leak, he underwent wedge resection of the lung and was pathologically diagnosed with metastatic angiosarcoma to the lung. He underwent radiotherapy following the lung resection, but he died from his disease at 15 month following surgery due to further aggravation of the lung metastasis. Angiosarcoma is a highly malignant tumor and it frequently occurs on the scalp and face in elderly patients. Angiosarcoma frequently metastasizes to the lung and it may cause pneumothorax as a consequence of a ruptured cavitary lesion. We report here on a case of pneumothorax that was caused by lung metastasis in an elderly patient with a history of angiosarcoma of the scalp.

  • A 68 year-old man visited our institution due to chest pain. Coronary angiography revealed triple vessel disease. A computed tomographic angiogram performed as a routine preoperative examination demonstrated an intraluminal spider-web-like mass from the infrarenal abdominal aorta to both common iliac arteries. The infrarenal aorta and both common iliac arteries were excised and replaced with concomitant off-pump coronary artery bypass grafts. Histologic examination of the aorta suggested an intimal sarcoma. A postoperative computed tomographic angiogram performed 3 months postoperatively showed no evidence of a residual or a recurred lesion.

  • A 14-year-old intact male Siberian Husky was presented with hematuria, lethargy, and anorexia of 1-month duration. The physical examination revealed mild abdominal distension and pain. The hematology and serum chemistry revealed anemia and severe azotemia. The radiographic examination revealed renomegaly and the ultrasonographic examination, indistinct cortico-medullary junction, increased renal cortex echogenicity, and irregular margination. The urinalysis showed proteinuria and hematuria. The differential diagnosis included renal failure, cystitis, pyelonephritis, and neoplasia. The patient's condition continued to deteriorate, and the dog eventually died. The gross findings from the necropsy revealed hemoperitoneum and a bilateral renal mass. HSA was diagnosed by histopathological examination. This case report describes primary bilateral renal hemangiosarcoma (HSA), which is uncommon in dogs.
