To the Editor.—
The question from Irwin H. Linden (221:720, 1972) concerning brown pigmentation of the skin along the veins following heroin injections brings a letter from the British Medical Journal (3:115, 1972) to my mind. D.W. Barlett described "a beneficial side effect arising from the treatment of obesity with fenfluramine." In a number of patients he saw fading, shrinking, or complete disappearance of pigmented naevi, severe erythema intertrigo, and red Campbell de Morgan spots after a few weeks of fenfluramine therapy. Fenfluramine might be an answer to Dr. Linden's question.
