case_images: An esophagogastroduodenoscopy (OGD) yielded unremarkable macroscopic findings of oedematous-appearing mucosa (Figure 1), and a small biopsy taken from the second portion of the duodenum region was sent for histopathological and PCR analysis.

case_images: Hematoxylin and eosin (H&E) staining of duodenal lamina propria showing intrusion of foamy macrophages as shown in Figure 2.
case_images: Depiction of characteristic D-PAS positive granular staining within the macrophages (arrows).. D-PAS refers to Periodic Acid-Schiff (PAS) with diastase.
