摘　　要：BACKGROUND Primary hepatic myelolipoma is a rare hepatic mesenchymal tumor mixed by adipose tissue and bone marrow,and there is a lack of general guidelines related to its epidemiology and clinical management.CASE SUMMARY A 26-year-old woman was admitted to our department complaining of a newly found tumor on her left lobe of the liver.The tumor was painless and not associated with any systemic or localized compressive symptoms.Serological tests disclosed a slight increase of gamma-glutamyl transpeptidase(70.0 U/L)and total bilirubin(19.2 pmol/L).Ultrasonography showed a mass about 5.0 cm x 5.0 cm in size that was located in the left lobe of the liver and displayed hyperechoic and well-encapsulated characteristics.Surgical resection was applied,and the following histopathological examination observed a variable proportion of myeloid tissues scattering throughout mature fibrotic adipose tissues,in which myeloid,erythroid,and megakaryocytic cells can be found in magnified view.The follow-up did not show any changes 6 mo after surgery.CONCLUSION This case highlights an extremely rare hepatic mesenchymal tumor,the primary hepatic myelolipoma,and discloses the common characteristics behind this disease and gives clinical recommendations.
