skin, or solid patches may be seen. The variety due to Ep. rubrum 

 has great tendency to spread to other regions of the body. 



In the cases caused by Trichophyton nodojormans the eruption 

 has thick elevated margins, and along the edge deep-seated nodules 

 resembling ' blind boils ' are present, the fungus being capable of 

 attacking the hair Ifollicles [and having [pyogenic properties. The 

 infection may spread from! the inguinal [regions to other parts of 

 the body. We have [seen ajcase presenting a nodular eruption due 

 to [this']fungus fin the [groins, and at the same time presenting a 

 typical kerion barbae due to the same organism on the right cheek. 



Regions of the Body aflected.^ — The eruption, as already stated, 

 is generally localized to the cruro-inguinal and axillary regions, 

 hence the name ' tinea cruris seu inguinalis ' ; but the same fungi 

 may spread in many cases from those regions to any other part of 

 the body, except the scalp. In some few cases the eruption may 

 first appear on the arms or chest, etc., and then spread to the groins 

 and armpits, or may never affect these regions. Hence the terms 

 ' tinea cruris ' and ' tinea inguinalis ' are not altogether appro- 

 priate, and the term ' tinea tropicalis,' or the native term ' dhobie 

 itch,' might be used as general terms to cover all the localizations. 



A localization of great importance noted by Sabouraud, and later
