pubmed:abstractText
Terminal ileal pigmentation was observed during colonoscopy, in surgically resected specimens, and autopsy cases. Microscopically, black pigment was seen within macrophages in the lamina propria and submucosa, closely related to the Peyer's patches. Three ilia from autopsies with no macroscopic pigmentation showed deposits following digestion and X-ray microanalysis. X-ray microanalysis of tissue sections and digestates revealed a heterogenous population of particles. Approximately one third of the particles contained calcium and phosphorus and were considered endogenous. The rest of the particles were predominantly aluminum and magnesium-rich silicates, which were considered exogenous. Analysis of particulate extracted from lungs and ilea of four autopsy cases demonstrated remarkable similarities in composition. These findings suggest that the ileal deposits are derived from atmospheric dust. This pigment is believed to migrate into the Peyer's patches through the M cells of the follicle associated epithelium, although other mechanisms for pigment deposition cannot be ruled out.
