A 12-year-old boy had lesions clinically and histopathologically consistent with lymphomatoid papulosis (LP) which were persistent and appeared grouped in a circumscribed area of normal looking background skin on the right abdomen. Staging work-up did not disclose systemic disease. Persistent agmination of lymphomatoid papulosis (PALP) is somewhat different from classical LP because it involves a circumscribed, patch-sized area of the skin and the papules within never resolve completely despite some waxing and waning. PALP might be considered a localized or regional form of LP or a distinct lymphoproliferative disorder; in any case, at least a cautious long-term follow up is recommended, with attention to the possible development of true lymphoma.
