PLEVA has a distinct clinical presentation, which aids in its diagnosis. The patient may have mild constitutional symptoms of fever and malaise. From a pathologic standpoint, ulcerated lesions are histologically nonspecific. Pityriasis lichenoides chronica manifests more gradually and is characterized by pink-to-brown 2- to 5-mm papules with central adherent scale, found primarily on the trunk and proximal extremities.

Pityriasis lichenoides et varioliformis acuta following measles rubella vaccine. Lymphomatoid papulosis is a chronic, benign, self-limiting disorder that is often clinically indistinguishable from PLEVA. MeSH PLEVA also typically has extravasation of erythrocytes, which is not a conspicuous feature of the aforementioned entities. In PLEVA there is a sharply delimited, sparse to moderately dense inflammatory cell infiltrate involving the superficial vascular plexus. Treatment has proven to be difficult and unpredictable. In fully developed, nonulcerated lesions of PLEVA, there is a superficial perivascular to lichenoid infiltrate with an accompanying wedge-shaped perivascular infiltrate extending into the underlying dermis.
