Las lesiones pueden ser discretas o pueden coalescer para formar placas. Histológicamente, hay un patrón en forma de "dientes en serrucho" de la hiperplasia epidérmica y alteración vacuolar de la capa basal de la epidermis, junto con un intenso infiltrado inflamatorio de la dermis superior compuesto predominantemente por células T.

Scope note: An inflammatory, pruritic disease of the skin and mucous membranes, which can be either generalized or localized. It is characterized by distinctive purplish, flat-topped papules having a predilection for the trunk and flexor surfaces. The lesions may be discrete or coalesce to form plaques. Histologically, there is a "saw-tooth" pattern of epidermal hyperplasia and vacuolar alteration of the basal layer of the epidermis along with an intense upper dermal inflammatory infiltrate composed predominantly of T-cells. Etiology is unknown.
