Abstract

Hepatocellular adenoma (HCA) is a rare benign tumor of the liver with low risk of malignant transformation. It is associated with oral contraceptives/anabolic steroid use, metabolic disease, and rarely, vascular abnormalities. We report an interesting case of HCA arising in a background of diffuse hepatic nodular regenerative hyperplasia (NRH) in a 40-year-old female patient with systemic lupus erythematosus (SLE). She presented with sudden-onset refractory ascites, elevated liver enzymes, diffuse hepatic nodularity and mass lesions on imaging concerning for malignancy. Targeted biopsies of the mass lesion were performed with inconclusive diagnoses. The patient ultimately underwent resection of the mass, which was confirmed as HCA, inflammatory type, arising in a background of NRH. It is not uncommon for SLE patients to have liver manifestations such as NRH, but HCA arising in NRH has not been previously reported. Our case reveals an unusual relationship between HCA and hepatic vasculopathy in the clinical context of a systemic inflammatory condition, the mechanism by which is not fully understood.
