Laparoscopic splenectomy for splenic sclerosing angiomatoid nodular transformation: A case report

Introduction: Sclerosing angiomatoid nodular transformation (SANT) is a rare benign and proliferative vascular lesion arising within the red pulp of the spleen. The lesion is often identified incidentally on imaging and the diagnosis is confirmed on pathologic assessment of the resected spleen. The lesion can be cured by splenectomy. Until now, little has been published on the laparoscopic approach for treatment of SANT. Case Report: A 5­cm splenic tumor was discovered during a routine examination of an asymptomatic 38­ year­old man. We were initially suspicious of fibrous hamartoma, but could not rule out malignancy. Consequently, laparoscopic splenectomy was performed, and histopathological findings showed that the tumor was a sclerosing angiomatoid nodular transformation. Conclusion: We report a rare case of sclerosing angiomatoid nodular transformation, completely resected by laparoscopy. In such cases, laparoscopic splenectomy seems to be a feasible, safe, and effective treatment.
