In pathology, hyaloserositis is the coating of an organ with a fibrous hyaline,[1] resulting from inflammation of the serous membrane (serositis) covering the organ.[2]
The spleen is commonly affected and often referred to as sugar-coated spleen.[3] The liver and heart are also sometimes affected and referred to as frosted liver (or sugar-coated liver) and frosted heart respectively.[1]
Hyaloserositis of the spleen is usually considered benign, i.e. it does not necessitate any treatment.
