A case of mesenteric panniculitis in a patient with Tangier disease.

Mesenteric panniculitis is a rare disease caused by idiopathic inflammation of adipose tissue, most commonly affecting the mesentery of the small bowel. We present a unique case of mesenteric panniculitis in a patient with Tangier disease; a rare genetic disorder caused by mutations in the ABCA1 gene, leading to deficiency of high-density lipoprotein in the blood and accumulation of cholesterol esters within various tissues. The accumulation of cholesterol esters in body tissues in patients with Tangier disease may contribute to the pathogenesis of mesenteric panniculitis; although there is limited evidence to support this hypothesis due to the rarity of concurrent disease.
