TROPICAL DERM ATOMY COSES 



TINEA ALBIGENA. 



This trichophytosis was first described by Nieuwenhuis in Java. 

 Nieuwenhuis' researches have been confirmed and enlarged by 

 Jeanselme in Indo-China and in Siam; in the latter country the 

 disease is known as khi. The disease is fairly common in the Malay 

 Archipelago, and is occasionally met with in Ceylon. 



etiology. — The affection is due to a Trichophyton first described 

 by Nieuwenhuis' — T. alhiscicans Nieuwenhuis, 1907. 



The spores in fresh preparations from scrapings are almost always 

 absent; the mycelium tubes are straight, occasionally showing a 

 double contour; they are often dichotomous. Nieuwenhuis has 

 grown the fungus, using Sabouraud's sugar media; the growth is 

 very slow ; the jcolonies are whitish, and show a powdery surface.

Symptomatology.- — The eruption generally affecis the palms of 

 the hands and the soles of the feet, but may extend to the fore- 

 arms and legs, and may affect the nails. It begins with the appear- 

 ance of small pruriginous spots on the palms and soles; the 

 epidermis becomes raised, and bullse develop, containing at first 

 clear serum ; the bullse break, and the skin remains dry and peels 

 off; the parts remain tender, and there is desquamation and pruritus. 

 A process of diffuse keratosis develops, the palms and solesbecoming 

 double their usual thickness; deep fissures may be formed at the
