background â vascular neoplasms are the most common primary splenic tumors that include both benignand malignant variants. one of these variants is hemangioma which is a benign vascular tumor. hemangiomas are slow growing and large tumors are rare. these tumors are most often incidental findings during imaging studies, laparotomy, or at autopsy. case presentation herein, we presented a young la...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 vascular neoplasms, other than benign are characterized as intermediate or malignant. they are often enshrouded in controversy, because the same neoplasm could show variability in biologic behavior that may not be correlated with microscopic features. the intermediate grade vascular neoplasm is named as epithelioid hemangi...

A liver neoplasm was found in a 63-year-old man with alcoholic liver disease. Sonazoid-enhanced ultrasonography (US) showed that the neoplasm was isoechoic at the early vascular phase and hypoechoic at the post-vascular phase. Gadolinium ethoxybenzyl-diethylenetriamine-enhanced magnetic resonance imaging (MRI) showed that the neoplasm was hypointense at the hepatobiliary phase. We suspected tha...

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...

Osteoblastoma is a rare solitary osteoblastic bone neoplasm. It is characterized by proliferation of osteoblasts forming trabeculae within a vascular fibrous stroma. There is a variety of jaw bone lesions with very close clinical, radiological and microscopic interrelations, which make diagnosis more challenging. Familiarity with these rare bony lesions is vital for oral pathologists. This repo...
