Hexagonal pyramidel crystals often occur with a great many eosinocytes in prostatic secretions from so-called prostatic eosinophilia patients. Assuming these crystals to be Charcot-Leyden crystals, the authors examined 43 urological cases including prostatic eosinophilia for the Charcot-Leyden-forming capacity of esoinocytes from the viewpoint of the fact that peripheral eosinocytes possess the capacity of forming the crystals.
Method of observation.
Blood was collected from the cubital veins twice on the fasting stomach early in the morning and 2 hours after the meal in an attempt to investigate the eosinocyte count and blood picture. Plasma was removed from a part of the blood by centrifugation, and the leukocyte layer was obtained. The blood was centrifuged again by the use of a hematocrit and supernatants were separated. The specimen was sealed and left intact at room temperature for 10 days. The bufy coat was smeared and observed to determine the presence or absence of Characot-Leyden crystal formation.
Results
The typical case of prostatic eosinophilia possesses the capacity of forming Charcot-Leyden crystals in all instances. That capacity is very scanty in other eosinophilia patients. In the opinion of the authors, the crystals can be considered Charcot-Leyden crystals
