Introductory. — There, came recently under the care of one of 
us (D. B. T.) an Egvptian soldier (Case I) with a peculiar skin 
lésion, the character of which is well shown in the accompa- 
nving photographs, taken bv Dr. Beam. The patient was sent to 
the Wellcome Research Laboratories where it was suggested 
that it would be well to examine the contents of the skin lésions 
and also to make a histological examination of the growths. This 
was done by one of us (A. B.) with the resuit that large num- 
bers of a species of Leishman-Donovan body, presumably L. 
tropica, were found, but while some sections of the growths bore 
a close resembiance in their pathological histology to true orien¬ 
tal sore, others presented peculiar features. Indeed, both clini- 
cally and histologically, the condition was at first suggestive of 
that rare skin disorder, which bears many different names, but is 
perhaps best described as benign multiple cystic epithelioma or 
épithélial cystadenoma of the skin. The history showed that we 
were dealing with a disease of considérable interest, an interest 
not lessened by the discoverv of a second very similar case which, 
in ail probability, had become infected from the first. 
It is proposed in the présent paper to discuss the condition 
generally, to give the clinical historiés of the two cases and to 
cleal with the microscopie findings, leaving till a later period the 
account of the attempts which are being made to cultivate the 
parasite, the animal inoculations, the feeding experiments with 
insects and the question of prophylaxie and treatment.
