Postlymphography linear dermatitis.
Cutaneous effects secondary to lymphography are rare events. We herein report a patient with Hodgkin's disease who developed a linear dermatitis in both lower limbs 6 days after a pedal lymphography. Histopathologic examination of the lesions demonstrated a subacute dermatitis. Patch tests with the substances used in the lymphography yielded negative results. We discuss the possible pathogenic mechanisms of this striking linear dermatitis.
