1/2. Evolution of a naevus spilus.

    The evolution of a naevus spilus is documented with serial photographs over a 12-year period. The lesion was remarkable for increasing numbers of macules and papules within the background of the cafe-au-lait macule. biopsy of a new papule showed lentiginous melanocytic hyperplasia without atypia. We advise photography and periodic follow-up of large, clinically atypical or changing naevi spili. Indications for considering biopsy of naevi spili, irrespective of size, include atypical clinical features or change in one of the hyperpigmented macules or papules, eventuating in an atypical clinical appearance.

2/2. Multiple lentigines confined to psoriatic plaques.

    The development of naevus spilus-like hyperpigmentation at sites of resolving plaques of psoriasis has been reported previously. Although the mechanism is not understood, puva therapy has been implicated in most cases. We report an additional case in which lentigines, confined to sites of resolving psoriasis, occurred following oral PUVA. We also describe similar clinical features in two patients who had not received PUVA, which strengthens the observation that this treatment is not a prerequisite for development of this unusual pattern of pigmentation.
