Histological sections of the skin lesion from nonulcerated or atypical cutaneous leishmaniasis (NUCL) processed by double-staining immunohistochemistry showing (a) CD68⁺ cells (blue), (b) iNOS⁺ cells (brown), and (c) M1 macrophages (CD68⁺/iNOS⁺) (×400). The red arrows show immunostained cells for the different markers.
