Splenic hamartoma mimicking angiosarcoma: A case report.

Background: Primary splenic lesions are rare and often detected incidentally through imaging, biopsy, or autopsy, typically without distinct clinical symptoms. Although imaging can help differentiate benign from malignant lesions, splenic hamartomas, and angiosarcomas may exhibit overlapping features, making diagnosis challenging. This report presents a case of splenic hamartoma suspected to be an angiosarcoma based on preoperative imaging.
