Microscopic lesions found in the placenta. A G1. Multifocal necrotic placentitis with very scant infiltration of inflammatory cells. B G2. Multifocal to coalescent severe necrotic placentitis. Note that inflammatory cells are found at the periphery of the necrotic foci. C G3. Isolated foci of necrosis, where the infiltration of inflammatory cells is more evident than in the placentas from G2 and G1. All pictures were taken at the same magnification. Bar 200 μm.
