Nonvenereal sclerosing lymphangitis of the penis is a peculiar disorder involving the lymphatics of the coronary sulcus. Three patients had the typical cord-like, nodular penile lesion which, upon palpation, had a characteristic cartilaginous firmness. The apparent rarity of the disorder may be misleading, since it is asymptomatic and enjoys a benign, self-limited clinical course.
