Abstract
We report a very rare case of a resected splenic tumor. A 30-year-old man was incidentally found to have a splenic tumor by ultrasonography during a medical examination. Ultrasonography and CT showed that the tumor was gradually increasing in size. The tumor showed high FDG accumulation on FDG-PET. Therefore, malignant disease could not be ruled out, and splenecomy was performed. On the basis of histopathological findings, the splenic solid tumor with a clear margin was diagnosed as sclerosing angiomatoid nodular transformation (SANT). SANT is a very rare tumor-forming disorder of the spleen that was initially reported in 2004. We describe our case and other SANT cases in Japan and review the relevant literature.
