Angiosarcoma is a rare and aggressive tumor with high rates of metastasis and relapse. It shows a particular predilection for the skin and superficial soft tissues. We report three distinct and typical cases of angiosarcoma that were diagnosed in a single dermatology clinic over the course of less than a year: i) Angiosarcoma in lower limb affected by chronic lymphedema, featuring Stewart-Treve...

BACKGROUND Primary hepatic angiosarcoma is a non-epithelial malignancy derived from sinusoidal endothelial cells, accounting for approximately 1.8% of primary hepatic malignancies. Diagnosis of primary hepatic angiosarcoma is complicated by difficulties in the qualitative radiological assessment of these tumors. Prognosis is very poor due to local recurrence and distant metastasis after liver r...

Angiosarcoma is a rare tumor of bone that uncommonly involves the skull. Primary neoplasms of the skull represent 2.6% of primary neoplasms of bone. We wish to report a case of angiosarcoma of he skull in an 18-year-old pregnant woman who presented with a rapidly growing left frontotemporal mass. Neuroimaging revealed a left frontotemporal mass with destruction of diploic space ...

BACKGROUND: Breast angiosarcoma is a rare disease occurring as primary tumour or secondary to lymphoedema or radiotherapy. The more frequent use of breast-conserving therapy and radiotherapy for breast carcinoma explains the increasing diagnosis of these tumours. CASE REPORT: We report a case of a breast epithelioid angiosarcoma which metastasized to the contralateral axillary lymph node, occur...

Angiosarcoma is a malignant vascular tumor originating from endothelial cells of blood vessels or lymphatic vessels. The specific driver mutations in angiosarcoma remain unknown. In this study, we investigated this issue by transcriptome sequencing of patient-derived angiosarcoma cells (ISO-HAS), identifying a novel fusion gene NUP160-SLC43A3 found to be expressed in 9 of 25 human angiosarcoma ...

BACKGROUND Angiosarcoma is a fatal and aggressive mesenchymal tumor. It occurs in skin, breast, and parenchymal organs. It rarely arises primarily in the urinary bladder. Only 13 cases of primary urinary bladder angiosarcoma have been reported in the English literature. CASE REPORT The patient was a 68-year-old man who presented to the Emergency Department with inability to void. Computed tom...

RATIONALE Angiosarcoma is an extremely rare malignant tumor of endothelial origin. The majority of studies reporting angiosarcoma have been concerned with the clinical and pathological aspects, with limited reporting of their imaging findings. To our knowledge, angiosarcoma of the adrenal gland is very rare. Herein we firstly report a primary adrenal angiosarcoma depicted on magnetic resonance ...

A 64-year-old man presented with a 2monthhistoryofmelena.Healsohadahistory of chronic renal disease, hypertension, and diabetes mellitus, and he had worked at a leather factory for decades. He was diagnosed as having primary hepatic angiosarcoma and had undergone right lobectomy 4 months before this admission. Esophagogastroduodenoscopy and colonoscopy failed todetect thebleeding source. Capsul...

Actas Dermosifiliogr. 2007;98:372-6 373 To the Editor: We describe a 57-year-old man with multiple basal cell carcinomas on the scalp, where he had undergone radiation therapy in childhood. He consulted for a pearly mass adjacent to a violaceous mass of 5 cm that was poorly defined, indurated, asymptomatic, and with several peripheral nodules (Figure 1), but no local or regional lymph node enla...

Primary uterine angiosarcoma is extremely rare and has a poor prognosis. Angiosarcoma (malignant hemangioendothelioma or hemangiosarcoma) is defined as a tumor of the endothelial cells that lined the blood vessels. It represents less than 1% of all soft tissue sarcomas (1). Although angiosarcomas can arise in any region of the body, most arise in the skin or superficial soft tissue of the elder...
