Abstract:

Summary

The aim of our study was to evaluate the long-term results of topical psoralen ultraviolet A (PUVA) in patients with necrobiosis lipoidica (NL), in whom conventional methods (pentoxifylline, vitamin E, tretinoin, and topical or intralesional corticosteroids) had failed. The study comprised 10 women (age range 17–44 years), six of whom were insulin-dependent diabetics and four were diabetes-free. Duration of NL ranged from 3 to 10 years. The patients were treated with a 0.005% aqueous solution of 8-methoxypsoralen, applied topically for 30 min, and subsequently irradiated with UVA three times weekly. All the patients experienced almost complete remission (softening of skin lesions, no hyperpigmentation, lack of lesion progression) after a mean of 47 sessions (mean UVA cumulative dose 69.5 J/cm²). They were followed up for 12–24 months, during which time two recurrences, both in diabetic patients, were observed after 8 and 12 months of treatment cessation, which further resolved after another course of topical PUVA. We conclude that topical PUVA is well tolerated by NL patients and may serve as an alternative therapeutic regimen.
