Pale infarct is seen in following except
White infarcts occur with aerial occlusions in solid organs with end-aerial circulations (e.g., hea, spleen, and kidney), and where tissue density limits the seepage of blood from adjoining patent vascular beds. Infarcts resulting from aerial occlusions in organs without a dual circulation typically become progressively paler and sharply defined with time . By comparison, hemorrhagic infarcts are the rule in the lung and other spongy organs . Extravasated red cells in hemorrhagic infarcts are phagocytosed by macrophages, and the heme iron is conveed to intracellular hemosiderin. Small amounts do not impa any appreciable color to the tissue, but extensive hemorrhages leave a firm, brown residuum. ( Robbins Basic Pathology, 9 th edition, page 92)
