Vascular smooth muscle tumors are very rare. They can be benign or malign. Intravascular leiomyomatosis is a benign neoplasm that extends through the veins and caries significant morbidity. Angioleiomyoma is a benign neoplasm of the extremities that caries minimal morbidity. Vascular leiomyosarcomas are malign neoplasms derived from vascular smooth cells. They are usually localized to the infer...

Intramuscular hemangiomas are rare benign vascular neoplasms. IMH accounts for less than 1% of all hemangiomas. These neoplasms commonly occur in trunk and extremities but are rare in head and neck region. The present case is a 17-year-old female patient, who presented with a painless, slowly enlarging mass in left sided upper neck for 4 years. Investigations were suggestive of vascular neoplas...

Primary sarcomas of the major blood vessels can be classified based on location in relationship to the wall or by histologic type. Angiosarcomas are malignant neoplasms that arise from the endothelial lining of the blood vessels; those arising in the intimal compartment of pulmonary artery are rare. We report a case of pulmonary artery angiosarcoma in a 36-year old female with pulmonary masses....

BACKGROUND: Majority of lower limb amputations performed in the African setting have been reported to be mainly due to trauma and neoplasms. These affect mainly young and therefore, fit individuals with lower risks of complications. Recent local studies show an increase in the incidence of cardiovascular diseases including peripheral vascular diseases. These are associated with higher rates of ...

Kaposiform hemangioendothelioma (KHE) is a rare vascular neoplasm that can be potentially low malignant and mainly affects infants and adolescents. This tumor usually is seen in the skin, soft tissue, and retroperitoneum. This study is a case of KHE in the long bone of the ulna. The subject was a 7-year-old female patient with osteolytic lesion in the forearm without cutaneous lesions. Histolog...

PURPOSE Oligodendroglial neoplasms with chromosome 1p deletion are chemosensitive, and stratified adjuvant therapies have been proposed on the basis of 1p status. In this study, we evaluated expression of hypoxia-related factors and its influence on survival in oligodendroglial brain tumors with chromosome 1p aberrations. EXPERIMENTAL DESIGN Forty-four primary and 16 recurrent oligodendroglia...
