Localized Lymphomatoid Papulosis: Unilesional Lymphomatoid Papulosis, Regional Lymphomatoid Papulosis, And Persistent Agminated Lymphomatoid Papulosis

Lymphomatoid papulosis (LYP), the most common primary cutaneous CD30-positive lymphoproliferative disorder, is heralded by multiple papular and nodular lesions at anatomically discontiguous cutaneous sites. The histologic patterns are protean. A very uncommon form of LYP is one that is anatomically confined. Cases of unilesional lymphomatoid papulosis, regional lymphomatoid papulosis and persistent agmination of lymphomatoid papulosis were encountered in the routine and consultative practices of Weill Cornell Medicine, Division of Dermatopathology.
