Lymphomatoid papulosis

Lymphomatoid papulosis is a chronic disease of cutaneous lymphoid infiltration characterized clinically by involuting and recurring papules, plaques, and nodules. The intriguing combination of a usually benign clinical course, a cytologically malignant lymphoid infiltrate on histologic examination, and a clear, but sporadic association with extracutaneous lymphomas has stimulated significant investigation. Application of recent technical advances to research in lymphomatoid papulosis prompts this review.
