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.
Case report: A 69-year-old patient was referred to our hospital with a tumor in the pancreatic tail which was suspicious for cancer. Radiologic work-up revealed furthermore a 4 cm in diameter large lesion central in the spleen suspicious for metastasis of the pancreatic tumor. The patient underwent surgery and a distal pancreatectomy with splenectomy was performed. Histologic specimen obtained a sclerosing angiomatoid nodular transformation in the spleen. The operative and postoperative course was uneventful.
Conclusions: SANT of the spleen are very rare tumors and should be considered as an important differential diagnosis to other vascular lesions.
