description: Littoral cell angioma is a rare primary vascular neoplasm of the spleen, composed of littoral cells that line the splenic sinuses of the red pulp. It was thought to be a benign, incidental lesion. However, many recent reports have described it to be a malignant lesion with congenital and immunological associations. The definitive diagnosis can only be made after histology and immunohistochemistry studies.
