			===Micro===
			The soft tissue section shows readily apparent rhomboid-shaped crystalline deposits
			(compatible with pseudogout). The crystals polarize and have a light blue hue under
			polarized light. Synovial hyperplasia is present. No lymphoid aggregates are apparent.

			The bony section show thin bony trabeculae and cartilage with
			degenerative changes (surface fibrillation, thinning).
