Abstract

Primary splenic tumors are rare and mainly found incidentally on radiologic studies. Among them, sclerosing angiomatoid nodular transformation (SANT) of the spleen is a new entity defined as a benign pathologic lesion. Most SANTs have no clinical symptoms and are occasionally accompanied by other splenic diseases such as malignancies. So, the exact diagnosis of the nature of the splenic tumor is mandatory for further treatment. But, preoperative diagnosis is not easy since it is difficult to obtain the tissue from the spleen for pathological study. Recently, laparoscopic splenectomy has become the more standard procedure for the spleen for diagnosis and treatment. Here, we report a rare case of SANT diagnosed following laparoscopic splenectomy.

  Fig. 4 Microscopic findings in sclerosing angiomatoid nodular transformation of spleen. (A) The tumor shows multinodular lesion surrounded by fibrosis. The nodules are irregular and composed of many small-sized vessels. The fibrotic area shows abundant collagen fibers and inflammatory cells hematoxylin-eosin (H&E, ×40). (B) The high power view of angiomatoid nodular lesion, it shows many vessels, extravasated red blood cells and inflammatory cells (H&E, ×100).
