Splenic Cord Capillary Hemangioma with Concurrent Hepatocellular Carcinoma—A Case Report—

Abstract

Splenic cord capillary hemangioma is a rare disease and is difficult to distinguish from a malignant tumor in the spleen. We report a case of this disease with a concurrent hepatocellular carcinoma (HCC). A 68-year-old man was admitted to our hospital with obstructive jaundice. Abdominal enhanced computer tomography (CT) showed an HCC in the anterior segment of the right hepatic lobe, with tumor thrombus located within the intrahepatic bile duct. However, many tumors were also seen in the spleen on CT. These splenic tumors were 3 to 14 mm in diameter and were enhanced in the early phase, but poorly enhanced in the late phase. Magnetic resonance imaging (MRI) showed low signal areas in these tumors on T1-weighted images and slightly high signal areas on T2-weighted images. We suspected a malignant tumor of the spleen and performed laparoscopic splenectomy. These tumors showed relatively well-demarcated macroscopic findings and increased vascular production on histopathological examination. Immunostaining results were positive for CD34 and negative for CD8. Therefore, we diagnosed a splenic cord capillary hemangioma. We should consider splenic cord capillary hemangioma if a splenic tumor shows abnormal findings on imaging.
