Figure 1 .
(A) Medium sized artery with acute and chronic transmural inflammation without signs of extension of the process to the surrounding tissue. The lumen is partially obstructed by a thrombus (magnification × 40, haematoxilin and eosin stain). (B) A typical Langhans-type giant cell can be clearly seen in the upper left corner. Other giant cells are barely discernible along the lower edge. The infiltrate is mainly constituted of granulocytes and mononuclear cells. Eosinophils are present in very limited amounts (no more than 2% of the infiltrating cells) (magnification × 200, haematoxilin and eosin stain).
