Incidental finding of sclerosing angiomatoid nodular transformation of the spleen.

Background: The prevalence of tumors in the spleen is rare; most tumors are benign and of vascular origin. In 2004 a vascular lesion was first described, the sclerosing angiomatoid nodular transformation (SANT), which is a benign lesion with good circumscription and multinodular angiomatoid appearance. We report a case of this rare tumor in the spleen which was incidentally found in a patient with a tumorous lesion in the pancreatic tail.
