PUVA therapy successfully cleared various dermatoses mainly confined to the 
palms and soles in 18 of 20 patients treated. The conditions treated were: 
plaque-type psoriasis, pustular psoriasis, endogenous eczema and persistent 
palmoplantar pustulosis. Seventeen patients were treated in a controlled study 
of PUVA therapy versus no treatment at all and in 16 of these patients the 
disease was cleared in the PUVA-treated areas while the untreated areas remained 
unchanged or deteriorated. Twelve of the 18 patients were maintained in a clear 
state by continued maintenance PUVA treatment over 6--31 months while 3 patients 
had a spontaneous remission and are free of disease off all treatment.
