Yellow bodies in superficial and deep lymph nodes

The prevalence of yellow bodies was studied in superficial and deep lymph nodes in material from 46 necropsies. They were found in 22.8% of the 359 lymph nodes collected, ranging from 35.6% of the mesenteric to 11.1% of mediastinal lymph nodes, and were significantly more prevalent in deep abdominal than in superficial groups. Sets of lymph nodes from individuals tended to show an 'all or none' variation in the proportion of nodes that contained yellow bodies, but the presence of the bodies was not significantly related to age, sex, or disease.
