Background: Scleredema adultorum (SA) is a rare connective tissue diso
rder for which no treatment has proven to be effective. Objective: Our
purpose was to determine the effect of bath-PUVA therapy on SA.Method
s: Three patients were treated. Clinical evaluation of skin induration
and thickness as well as ultrasonography were performed at baseline a
nd after treatment. Results: All three patients showed substantial cli
nical improvement with bath-PUVA therapy (median of 59 treatments and
a cumulative UVA dose of 245.7 J/cm(2)). Ultrasonography showed signif
icant reduction in both skin thickness and density. Conclusion: Bath-P
UVA therapy appears to be effective in the treatment of SA.
