Fig. 34. Acute dermatophytosis of the hands. There may be a focus on the webs of the 

 feet, on the soles or elsewhere, or the infection may be primary. With secondary infection, 

 dissemination may take place externally or through the medium of the blood stream. A, acute 

 vesicular rash secondary to lesions on the feet. While this might be classed as dermatophytid, 

 T. gypseum was isolated from the lesions. B, primary erythematous vesicular infection of short 

 duration from which T. gypseum was isolated. There were no lesions on the feet. C, well 

 defined subacute rash of the hand, with part of an eruption also on the feet, elbow and face, 

 of one year's duration. D, early involvement of nails, showing destruction and separation at the 

 base The violence of the process produced a spontaneous cure, and new nails were normal.
