BULLOUS ERUPTIONS. 



Epidermolysis bullosa is occasionally observed. 



Pemphigus vulgaris and Septic pemphigus cases are not rare in 

 the tropics. In the cases of septic pemphigus we have always 

 found virulent streptococci. The eruption is similar to what one 

 sees in temperate zones. We have seen a case of Pemphigus 

 vegetans, and we have observed a typical case of Pemphigus folia- 

 ceus, contracted in Ceylon, and another in Indo-China. Dermatitis 

 herpetiformis is not rare. 



Of Hydroa vacciniformis we have seen two cases in European 

 children.) 



HERPES. 



Herpes facialis febrilis is common during attacks of malarial fever 

 and other fevers, but very rare, as is well known, in enteric. 



We have seen in European children a similar condition to what 

 some French writers call fievre herpetiqiie. The condition, as seen 

 by us, is characterized by a sharp attack of fever lasting about

twenty-four hours, and at the same time by the appearance of a 

 few herpetic vesicles — in our cases on the thighs and buttocks. 



Herpes progenitalis is very common, especially in Europeans. 



Herpes zoster (zona, shingles) is frequently met with in Europeans 

 and natives.
