title: Multifocal epithelioid hemangioendothelioma of the phalanges of the hand.
abstract: Epithelioid hemangioendothelioma (EH) of bone is a rare vascular neoplasm characterized by epithelioid endothelial cells and a variable biologic behaviour. The principal sites of occurrence of this osteolytic tumor are the lower extremity and the axial skeleton. Approximately half of the cases present with multifocal disease. The latter feature can be helpful in suggesting the diagnosis of a vascular tumor; on the other hand, it strengthens the need for a skeletal survey or whole-body MRI/CT. We report on the clinical, histologic and radiologic features-including CT and MRI findings-of EH in a case of multifocal disease of the phalanges of the hand, a very uncommon anatomic site of affliction.
