A 76-year-old @entity1 complained of difficulty breathing. A solitary mass was found in the spleen by ultrasonography and the @entity5 was excised. Grossly, the @entity5 was 3.9 x 2.9 cm in size, solid and brownish in color. A stellate scar-like @entity82 was observed in the center of the @entity5 . Histologically, the @entity5 consisted of the proliferation of irregular and @entity6249 , with @entity3808 change in the center. The lymph vessel-like spaces showed papillary projections of the lining cells. The lumen contained amorphous proteinaceous fluid. Immunohistochemically, the lining cells of lymph vessel-like spaces were positive for endothelial markers ( @entity2279 , @entity2280 , factor VIII-related antigen), and bound Ulex europaeus agglutinin-1. The @entity5 was diagnosed as @entity2696 , but its appearance was rather unusual for a typical @entity2696 because of the presence of papillary endothelial proliferation and scar-like @entity82 . @entity2696 with papillary endothelial proliferation is uncommon, and there have been only four cases reported.
