There are small areas of basal vacuolar change associated with minimal exocytosis of lymphocytes and occasional degenerate keratinocytes. This form of the skin condition pityriasis lichenoides is called pityriasis lichenoides et varioliformis acuta (PLEVA). The lesions often occur in crops, and are thus present in different stages most commonly on the trunk, but may spread to the extremities. Although the eruption is self-limiting and usually heals without scarring, it may evolve for 510 years. Ill discuss this in greater depth in a future post, but there are three generally accepted hypotheses on the mechanism behind the chronic skin inflammation that characterizespityriasis lichenoides: It took three months and three missed diagnoses from the momentmy symptoms first appeared to the point whenmy mysterious red spots were biopsied and conclusively identified as pityriasis lichenoides et varioliformis acuta(PLEVA). Although most children do well without treatment, phototherapy with UVB, PUVA, or natural sunlight may be useful in persistently symptomatic individuals. In addition to interface change, the epidermis is spongiotic with parakeratosis-prominent exocytosis of lymphocytes and often exocytosis of erythrocytes. Keywords: Bowers S., Warshaw E.M.
