Figure 6-23 — Chylous effusion. Pleural. Cat. A-B same case as in Figure 6-21B.

A, Note small lymphocytes, neutrophils, one eosinophil (arrow), and one large macrophage. Initially chylous effusions contain predominantly small lymphocytes and macrophages. As the duration of fluid presence increases, neutrophils and eosinophils will increase in number. (Romanowsky; HP oil.) B, Concentrated preparation. Note the punctate lipid vacuoles within macrophages along with small lymphocytes, neutrophils, and low number of red blood cells. (Romanowsky; HP oil.)
