CHAPTER OF FLUID OF ABDOMINAL TUMORS. PLATE OF AN OVARIAN CYST. 190 CLINICAL MICROSCOPY. CONTENTS OF AN OYAEIAN CYST. They can without the microscope be distinguished from asciticfluid by the fact that, even after twenty-four hours, they do notcoagulate like the latter. With the microscope we find in the liquid of an ovarian cyst,almost constantly, almost pathognomonically, cells (1) measuringfive to thirty fi, with a granular appearance, and frequently withplainly distinguishable fat-globules; occasionally Cholesterin crys-tals (2), well crystallized; leucocytes (3), red Mood-corpuscles^ fat-globules (4); colloid concretions (5) in cysts with inspissated contents(they have an irregular shape, are homogeneous, and of a pale-yel-low color); detritus (6) in cysts which have repeatedly been punc-tured ; ciliated cells (7) (important for differential diagnosis fromascites) lining the walls of the
