Palmoplantar psoriasis and eczema can be chronic recalcitrant dermatoses. Oral psoralen plus ultraviolet A (PUVA) has proven effective for these, but has a number of unwanted side effects. Previous studies have shown that regional PUVA therapy using the 8-methoxypsoralen (8-MOP) soak method followed by immediate UVA irradiation is also beneficial and well tolerated. The purpose of this audit was to determine the efficacy of hand and foot PUVA soaks by reviewing the experience of the Massachusetts General Hospital's Phototherapy Unit with this treatment modality. Phototherapy records of all patients who underwent hand and foot PUVA soaks from 1994 to 1998 were reviewed. Details regarding the treatment procedure, patient compliance, patient response and incidence of side effects were noted and summarized. Of the 56 patients who underwent at least 20 treatments, 29% had excellent response, 42% had minimal to moderate response, and 29% had poor response. The average number of treatments to induce clearing was 41. The average maximum treatment dose at clearing was 5.85 J/cm2, while the average cumulative dose to achieve clearing was 267.17 J/cm2. 8-MOP PUVA soak therapy is quite useful for chronic hand and foot dermatoses. Patient compliance must be emphasized to obtain favorable results.
