MULTIPLE LENTIGINES CONFINED TO PSORIATIC PLAQUES

The development of naevus spilus-like hyperpigmentation at sites of re solving plaques of psoriasis has been reported previously.(1-4) Althou gh the mechanism is not understood, PUVA therapy has been implicated i n most cases. We report an additional case in which lentigines, confin ed to sites of resolving psoriasis, occurred following oral PUVA. We a lso describe similar clinical features in two patients who had not rec eived PUVA, which strengthens the observation that this treatment is n ot a prerequisite for development of this unusual pattern of pigmentat ion.
