			===Duodenum===
			<pre>
			Duodenum, Biopsy:
			- Small bowel mucosa with pseudomelanosis, otherwise within
			normal limits, see comment.

			Comment:
			Pseudomelanosis of the duodenum (pseudomelanosis duodeni) may be seen in the context of iron supplementation, hypertension or chronic renal failure. Endoscopically, it may manifest as dark spots.

			The pigmented cells are POSITIVE with an iron stain, NEGATIVE with a PAS stain and NEGATIVE with a Fontana-Masson stain; these findings are in keeping pseudomelanosis duodeni.
