Accumulation of foamy lipid-laden histiocytic cells is most often seen in the skin and tendons, usually associated with congenital or acquired hyperlipidaemia, as seen in patients with diabetes mellitus, obstructive jaundice, and familial hypercholesterolaemia. The pathogenesis of xanthomatous lesions in other sites, including the urinary bladder,1 prostate,2 and gastrointestinal tract seems to be less consistent. Within the gastrointestinal tract the gastric mucosa is the most frequently cited location. Involvement of the oesophagus and bowel has rarely been described. Only three such cases largely confined to the small bowel have previously been documented. We here present an additional small bowel example accompanied by a short review of the existing literature in English on gastrointestinal xanthomatous lesions, including a discussion on its possible pathogenesis.
Histologically, the lesion is unique and a correct diagnosis does not pose significant difficulties. Identification of diverse phagocytosed cytoplasmic deposits in other histiocytic lesions may require ancillary studies.
