ABSTRACT— Portal lipogranulomas in liver biopsy specimens were investigated. The incidence of biopsies containing portal lipogranulomas was 2.4%. Out of 20 biopsies with lipogranulomas 10 biopsies contained only one lipogranuloma. Portal lipogranulomas show a distinctive morphology with fat vacuoles surrounded by macrophages. They are consistently found together with parenchymal steatosis and probably originate from parenchymal fat being transported to portal tracts. Portal lipogranulomas are of importance in the differential diagnosis from other granulomas.
