title: Mesenteric panniculitis presenting as liver dysfunction.
abstract: Mesenteric panniculitis is a non-specific inflammatory disorder affecting adipose tissues of the mesentery. Mesenteric adipose tissues contain macrophages and other inflammatory cells, which may secrete tumor necrosis factor α, interleukin (IL)-1, and IL-6. These cytokines collect into the portal vein and thereby flow into the liver, possibly influencing hepatic function. Mesenteric panniculitis often occurs with inflammatory reactions such as fever and elevated erythrocyte sedimentation rates. Systemic inflammatory disorders can evoke acute cholestatic liver involvement, which is mediated by proinflammatory cytokines. However, no reports have focused on the association between mesenteric panniculitis and liver involvement. We report a rare case of mesenteric panniculitis presenting as liver dysfunction. Immunohistochemical staining of the liver demonstrated a marked decrease in expression of canalicular transport systems. These findings indicated cholestatic liver dysfunction associated with mesenteric panniculitis.
