The presence of non-caseating epithelioid cell granulomas (Gr) with a surrounding layer of lymphocytes (hematoxylin-eosin staining, ×10) is shown in A). CD68 immunostaining in alveolar macrophages (AM), epithelioid cells (Ec) (×10) is shown in B) and CD68 immunostaining in a multinucleated Giant cell (Gc) and epithelioid cells (Ec) (×40) is shown in C).Back to article page
