Primary angiosarcoma of pulmonary artery is a very rare lesion. We present a case of primary angiosarcoma that was initially misdiagnosed as a subacute massive pulmonary thromboembolism in a 30-year-old man. This rare disease is usually indistinguishable from acute or chronic thromboembolic disease of the pulmonary arteries. The clinical and radiological findings of pulmonary artery angiosarcom...

Angiosarcoma is a highly malignant vascular tumor of endothelial origin. Initially, a cutaneous manifestation presents as a singular or multifocal bruise-like patches on the skin, most frequently on the face, the scalp or the neck regions. On progression, the lesions become violaceous, and ill-defined spongy nodular tumors appear. Our patient was a 71-year-old man with a previous history of ang...

BACKGROUND Epithelioid angiosarcoma is a rare variant of angiosarcoma, and is characterized by an epithelioid morphologic appearance that mimics carcinoma. These tumors usually arise in extraskeletal sites; origination in bone is rare. CASE PRESENTATION A 69-year-old woman presented with right knee pain. Plain radiographs and magnetic resonance imaging showed an osteolytic lesion with a large...

A 60 year-old woman was admitted to our hospital because of management of multiple liver tumors. According to image findings and liver biopsy, she was diagnosed as having epithelioid hemangioendothelioma of the liver accompanied by metastases in the spleen, lungs and bones.

BACKGROUND The prognosis of angiosarcoma is poor and a novel treatment option for the disease is desired. The aim of this study was to investigate the prognostic significance of Forkhead box M1 (FOXM1), a transcription factor that regulates cell-cycle progression and various crucial processes in tumor progression, and its potential as a new therapeutic target. METHODS We investigated 125 angi...

Splenic angiosarcoma has been presented as an extremely rare malignant tumour. Amongst the rarest of all neoplasms, primary splenic angiosarcoma comprises 0.14-0.25 of all annually reported cases per one million persons Splenic angiosarcoma was first described in 1879 by T. Langerhans. The clinical symptoms and diagnostic values associated with splenic angiosarcoma are extremely variable. Nonet...

Angiosarcoma is a rare malignant tumor with an aggressive clinical course and a poor prognosis. Intraperitoneal angiosarcoma, especially originating from the omentum, is extremely rare. We report a case of radiation-induced angiosarcoma of the omentum that arose in a 38-year-old female seven years after concurrent chemoradiotherapy for cervical cancer. The primary tumor was unknown until diagno...

Angiosarcoma is a rare disease of the breast with the reported incidence of only 0.04% of all breast malignancies. The etiology of angiosarcoma remains unknown. It occurs post-mastectomy, in association with chronic lymphedema (Stewart-Treves syndrome), or after radiotherapy. We present a patient with angiosarcoma which developed 12 years of the diagnosis of breast carcinoma and 8 years of the ...

Angiosarcoma is a rare disease with a poor prognosis; significantly, patients with intestinal angiosarcomas who survive over 1 year after diagnosis are extraordinarily rare. This article describes the case of a 33-year-old gentleman who presented with abdominal pain of 4 months duration, which had increased in severity 2 weeks prior to presentation. After a complicated diagnostic and therapeuti...
