Lymphomatoid papulosis is a skin disorder that is characterized by crops of self healing skin lesions that look cancerous under the microscope but are actually benign (non-cancerous). Lesions contain unusual cells that are similar to those found in some lymphomas (cancers of the lymphatic system).[1]
