Primary splenic angiosarcoma. An aggressive and infrequent pathology.

Splenic angiosarcoma is a very rare and aggressive neoplasm originating from the splenic vascular endothelium whose prognosis is very poor despite surgical treatment. Preoperative diagnosis using imaging tests is a challenge due to its similarity to other vascular splenic tumors. The most common treatment is splenectomy, although it is rarely curative because of the aggressive and metastatic nature of the disease.
