AGUILERA GONZALEZ, María Paz et al. Splenic SANT: Uncommon tumor. Rev Cient Cienc Méd [online]. 2023, vol.26, n.1, pp.88-94.  Epub 31-Jun-2023. ISSN 1817-7433.

Nodular Angiomatoid Sclerosing Transformation of the Spleen (SANT) is a rare pathology, which affects blood vessels benignly with extensive sclerosis of the red pulp. A 24-year-old man consulted in a private center (Paraguay) for a 7-month course of paroxysmal dyspnea and cold sweating. Physical examination and laboratory evaluation show no abnormalities. Abdominal ultrasound shows a spleen with heterogeneous parenchyma and a pseudonodular image that is 48mm x 41mm in diameter. Contrasted MRI confirms the finding of an irregular nodule, with enhancement that predominates in the periphery of the arterial phase, with radiated appearance and centripetal filling in venous and late phase. Histopathology confirms diagnosis of SANT. SANT is frequent between 45 and 48 years of age, manifested with splenomegaly and scarce symptomatology. The presentation of this case differs with literature. Considering the lack of auxiliary methods to rule out malignancy, a splenectomy is performed.
