Core Tip

Core Tip: Splenic hamartomas are rare benign lesions that can closely mimic malignant tumors such as splenic angiosarcomas on imaging. We present a case initially suspected as splenic angiosarcoma with hepatic metastases, but histopathology after splenectomy confirmed splenic hamartoma. This rare case of splenic hamartoma mimicking angiosarcoma highlights the importance of differential diagnosis in managing splenic tumors.
