TWO CASKS OF NON-ULCERATING "ORIENTAL SORE ' 



When punctured they either yield blood alone, or blood with serum, or blood and 

 a siimll (juaiitity of wliite cheesy sebaceous-like material. After puncture, the site of 

 injury heals readily, and a small scale or scab forms. This is well seen in Fig. 41. On 

 section to the naked eye the growths appear fibrous. The following are the measurements

Blood exauiinalion. — An examination of blood taken from the finger, made on 

 October 10, showed 6,050,000 red blood corpuscles and 5,600 leucocytes. Lencopenia 

 therefore is present. The haemoglobin was not determined — the blood was of a good 

 colour. Its coagulability was markedly increased. A differential leucocyte count was 

 made with the following result: — 



Eosinophiles 

 Polymorphs ... 

 Slononuclears 

 Large lymphocytes 

 Small lymphocytes 

 Transitionals 



Characlerislic 

 ilifference-s 

 Iwtween the 

 blood from the 

 papules and 

 that from the 

 general 

 circulation 



With the exception, therefore, of a marked eosinophilia, the result probably of infection 

 with metazoan parasites, so common in these fellaheen, the count was nortiial. No 

 protozoal parasites of any kind were found. 



Very different was the differential count in blood taken at the same time from the 

 growth on the neck. It gave :- 



Eosinophiles 



Polymorphs 



Mononuclears 

 Large lymphocytes 

 Small lymphocytes.. 

 Transitionals 

 Basophiles ... 



There were many free nuclei of disintegrated mononuclears. Here, then, we find 

 a marked increase of the larger mononuclear cells at tlie expense of the polymorphs.
