Transmission and scanning electron microscopy of omental milky spots. (A) Electron microscopy revealed that the cell composition of the milky spots was largely composed of abundant macrophages (M). (B) Some lymphocytes (L) and neutrophils (N) were also noted (magnification, 4,000X). (C) In the milky spot areas, the surface layer cells consisted of macrophages, lymphocytes and discontinuous mesothelial cells and were separated by intercellular gaps or pores. (D) In the non-milky spot areas, intercellular gaps or pores were not observed (magnification, 500X).
