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.
对肝活检标本中的门脉性脂肪肉芽肿进行了研究。含有门脉性脂肪肉芽肿的活检发生率为2.4%。在20例有脂肪肉芽肿的活检中，10例活检仅含有一个脂肪肉芽肿。门脉性脂肪肉芽肿呈现出独特的形态，有被巨噬细胞围绕的脂肪空泡。它们始终与实质脂肪变性同时存在，可能起源于被转运至门管区的实质脂肪。门脉性脂肪肉芽肿在与其他肉芽肿的鉴别诊断中具有重要意义。
