ANGIO-FIBROMA CONTAGIOSl'M TROPICUM 461 



ANGIO-FIBROMA CONTAGIOSUM TROPICUM. 



A disorder of unknown causation found only in Southern Brazil. 



After an incubation of fifteen to twenty-five days there is an 

 eruption of red papules developing rapidly to the size of peas or 

 almonds. 



The face, neck, axilke and genitals are most cimnionly affected, 

 also the mucosae. The papules bleed readily. There is no fever. 

 They clear up spontaneously without any scar. 



ASPERGILLOSIS. 



A chronic fungus affection of the hairs of the beard and moustache 

 bv the Aspergillus barbae. Penicillium barbae is also commonly found 

 at the same time. 



Shave the hair and use turpentine, followed by carbolic, tar, or 

 sulphur soap. 



BARCOO ROT. 



This is a condition closelv allied to, if not identical with, the 

 " \'eldt sore " of Africa. There are blebs in an inflammatory area 

 containing thin pus, which arise on the backs of the hands and wrists 

 which develop into shallow ulcers. There is a preponderance of 

 staphylococci in the blebs and earlv afifecled hairs. 



Exposure and exhaustion predispose. 



Epilation of the affected hairs and ordinary- antiseptic treatment 

 under good conditions will soon clear up the condition. 



BIOTRIPSIS (Life-wear). 



A general atrophic condition due to old age (idiopathic a.lrophy). 



BLASTOMYCOSIS. 



Blastomvcetic dermatitis is a chronic (five to ten years) inflam- 

 matory disease of fungus origin caused by the genera, Saccharomyces, 

 Cryptococcus, Coccidiodides and Monilia. 



SYMPTOMATOLOGY. 



A reddish maculo-papule appears, becomes infected and suppurates. 



The papules become ulcerated nodules, which spread in extent and 

 depth, producing a raw and ulcerated mass. The dorsum of the hand 

 and the front of the leg are usually attacked first, but any part may be 

 affected. The alse nasi and the lips mav be destroyed. The disease 

 is not confined to the skin, but mav affect the internal organs. 



The disease may last for A-ears and then clear up spontaneously, 

 leaving a soft smooth scar. 



There is very little pain and the lymphatic glands are not enlarged. 

 On close examination numerous miliary abscesses are seen in which 

 the parasites, epithelioid and giant cells can be found.
