These results suggest that UVA1 phototherapy does not improve cutaneous thickness in acrosclerosis even if few functional improvements, and some ulcerations healings can be occasionally observed. However, a larger scale trial is necessary to confirm this inefficiency.

We report first cases of photodynamic treatment of erythrasma. There are other reports of clinical applications of antimicrobial action of photodynamic therapy in dermatology (acne vulgaris, leishmaniasis, warts, etc.). But there are few applications without addition of exogenous photosensitizing agent. The originality and interest of our study is to use spontaneous presence of porphyrins in the lesions. This technique seems to be an interesting alternative, inexpensive and easy, for the treatment of this localized infection. But an optimal method is still to be determined to improve efficacy.
