Histologic lesions identified in small intestine and lymph node. A is ileum, score = 1 due to focal granulomatous inflammation with multinucleated giant cells (*); B is ileum, score = 3 due to coalescing granulomatous inflammation in lamina propria (*) and submucosa (not shown), with multinucleated giant cells (**); C is lymph node cortex, score = 1, due to focal granulomatous inflammation in the subcapsular cortex (*); and D is lymph node cortex, score = 3 due to coalescing granulomatous inflammation in subcapsular cortex (*) and extending throughout the node (not shown). All images are H&E stained, viewed at 100× magnification.
