A case report of splenic malignant tumor originating from liver

Abstract

Abstract Splenic tumors are infrequently encountered in clinical practice, with a metastatic tumor incidence estimated to be approximately 2%-4% of all splenic tumors. Metastatic tumors originating from the liver are even more uncommon. Given the scarcity of reported cases and limited literature on splenic tumors, particularly in recent years, clinicians face significant challenges in effectively managing this disease. In this report, we present a case of a malignant splenic tumor originating from the liver. The patient, a 58-year-old male, was admitted to our hospital over a week after the identification of a splenic mass. Notably, the patient had previously undergone liver cancer surgery at our institution two years prior. Based on the patient's clinical presentation, physical examination findings, and additional diagnostic tests, we performed a surgical procedure known as "left outer lobe resection of liver + splenectomy + cholecystectomy". The postoperative pathological analysis confirmed the presence of recurrent hepatocellular carcinoma with splenic metastasis. Combining domestic and international literature, we now report a case of splenic malignancy of hepatic origin. In this case report, we aim to present its differential diagnosis and treatment options for clinicians' reference.
