We report a case of a 24-year-old @entity1 who presented with @entity490 , a tense abdomen, and rebound tenderness. A vague, ill-defined mass was palpated, and an ultrasound examination revealed a @entity5409 in the left adnexal region. At laparotomy, a slightly dilated fallopian tube was seen and excised. Light microscopy showed @entity5274 , with a diffuse infiltrate of foam cells in the lamina propria. There were no associated inflammatory cells. The foam cells were positive for @entity469 and negative for @entity1325 / @entity1326 . Discontinuous areas of the epithelium also showed epithelial cells with "foamy cytoplasm." These cells were negative for @entity469 but positive for @entity1325 / @entity1326 . To our knowledge, this represents the first case of a fallopian tube xanthelasma that shows a resemblance to lesions encountered in the stomach. @entity5274 must be distinguished from @entity9414 , which is associated with an inflammatory cell infiltrate, often including giant cells. However, this lesion may share pathogenetic similarities with @entity9414 , since both processes are mediated by inflammation.
