2. Fig 1
Granulomas in patients with BS. A, Hematoxylin and eosin staining of a large polycyclic granuloma with emperipolesis of lymphocytes within MGCs (black arrows; original magnification ×400). B, Hematoxylin and eosin staining of emperipolesis-associated MGC death (original magnification ×400). C, Dense IFN-γ staining within and around a polycyclic granuloma (original magnification ×200). D, Dense IL-6 staining as in Fig 1, C (original magnification ×200). E, Moderate TGF-β staining of intragranulomatous lymphocytes close to a small MGC with emperipolesis (black arrow; original magnification ×400). F, Dense IL-17 staining within and around a polycyclic granuloma (original magnification ×200). Images were acquired with a Leica DMLB microscope (Leica Microsystems, Wetzlar, Germany; objective lenses ×5, ×10, ×20, ×40, and ×100). The digital camera was a Leica DC 300 V (Leica Microsystems AG), and image processing was done with Leica IM50 Image Manager.

3. Fig 2
Granulomas in patients with NOD2-associated CD. A, Hematoxylin and eosin staining of a small isolated granuloma (original magnification ×400). B, Hematoxylin and eosin staining of eosinophils (black arrows) and sclerosis of surrounding tissue (original magnification ×400). C, Dense TNF-α staining of a granuloma (original magnification ×400). D, Mild TGF-β staining of lymphocytes around a granuloma with an MGC exhibiting mild emperipolesis (black arrow) and a crystalline inclusion (gray arrow; original magnification ×400). E and F, Moderate IL-23R staining (original magnification ×400; Fig 2, E) and exceptional IL-17 staining of a GIF in the mucosa-associated lymphoid tissue of the colon (original magnification ×200; Fig 2, F). Images were acquired as described in Fig 1.

4. Fig 3
Granulomas in patients with BS. A, HLA-DR staining of a large polycyclic granuloma in the spleen of case 5 (original magnification ×200). B, CD68 staining visualizes MML cells. (original magnification ×200). C, CD4 staining shows a dense corona of lymphocytes surrounding the granuloma (original magnification ×200). D, CD8 staining shows few CD8+ lymphocytes in and around the granuloma (original magnification ×200). Images were acquired as described in Fig 1.
