TROPICAL DERMATOMYCOSES 



with a salt-free diet. If potassium or sodium iodide is not well 

 borne, sajodin and other similar preparations may be tried, but the 

 result is not so satisfactory. Mercury and arsenic have no effect on the 

 course of the malady. As regards local treatment, it is sufficient to 

 keep the ulcers clean by using a weak mercury perchloride lotion. 



CRYPTOCOCCOSIS EPIDERMICA. 



Synonym. — Saccharomycosis epidermica (Castellani). 



Historical and Geographical.— This condition was first described 

 by Castellani in Ceylon. We have recently found cases in the 

 Sudan and in the Balcanic Zone, 



' etiology.— The causal organism is Crypiococcm epidefntidis 

 Castellani, 1914. 



Symptomatology.— The condition is fairly frequent in Europeans 

 who have resided for some years in the tropics, but is also found in 

 natives. It is characterized by the presence on the arms, and more 

 rarely on the chest and neck, of small roundish patches of a dirty 

 yellow or brownish colour, which can generally be removed by 

 thorough scraping. These patches consist of large numbers of 

 blastomyces-like elements of various size, rounded or oval, which 

 so far have not been cultivated. 



Treatment. — Thorough scraping with sand-soap and hot water is 

 generally sufficient to remove the patches. In obstinate cases a 

 salicylic sulphur ointment is useful. 



INTERTRIGO SACCHAROMYCETICA. 

 Synonym. — Intertrigo Blast omycetica. 



Remarks. — Cases of this affection have been observed by Castel- 

 lani in Ceylon, and similar ones have later been reported by 

 Whitfield and others in Europe. The affection is apparently rare. 

 It generally attacks the scroto-crural and axillary regions. The 

 affected skin is red, and there may be slight exudation. The 

 borders of the eruption are fairly well marked, but never elevated. 

 In most cases there is not much itching, and the affection may 

 recover spontaneously. 



etiology.— In scrapings a Saccharomyces [S. samhoni Castellani, 

 1907), which is easily cultivated on sugar media, is found, or in other 

 cases fungi of the genus Monilia. 



Treatment. — The treatment consists in washing the affected parts 

 with potassium permanganate lotion, i in 4,000, or resorcin, i in 100 ; 

 followed by the application of powders of boric acid 3i., talci §i.; or 

 salicylic acid gr. x., talci §i. I 



ASPERGILLOSIS AND PENICILLIOSIS OF HAIRY PARTS. 



The affected hairs — generally those of the beard and moustache, 

 occasionally of the axilla — ^present dirty greyish or whitish puncti- 

 form formations, which on microscopical examination are seen to 

 consist of penicillar or aspergillar fungi {Penicillium harhcB, Asper-
