splenic vascular tumors

Primary vascular neoplasms of the spleen constitute the majority of non-hematolymphoid splenic tumors.

The benign primary vascular tumors include hemangioma, hamartoma, and lymphangioma, whereas those of variable or uncertain biologic behavior include littoral cell angioma, hemangioendothelioma, and hemangiopericytoma.

The primary malignant vascular neoplasm of the spleen is angiosarcoma.

Peliosis is a rare lesion of unknown cause that is usually found incidentally in asymptomatic patients but may be associated with hematologic or metastatic disease.
