Macrophage

A large amoeboid white blood cell with an irregular blob-like outline, uneven ruffled or softly lobed membrane edges, and abundant pale cytoplasm in beige, tan, light pink, light purple, or blue-gray tones. The cell often shows short blunt pseudopodia or broader surface extensions suggesting active movement or phagocytosis. The cytoplasm may be slightly granular and can contain a few small round vesicle-like inclusions suggestive of engulfed material. A single prominent darker nucleus is present, typically kidney-shaped and dark purple, though it may appear oval or more rounded in simplified depictions.
