Abstract/OtherAbstract:
We present the endoscopic, microscopic, and histochemical studies of a patient with pseudomelanosis of the duodenum. The pigment was located mainly in the lysosomes of macrophages in the lamina propria and was heterogeneous, showing features of melanin, pseudomelanin, and hemosiderin. The origin of this pigment remains unknown, but antihypertensive medication may have played a role.
