Lame perforating elastic tissue degeneration

Elastosis perforans serpiginosa is a claudication disease. Lutz reports that the disease is called penetrating elastofibrosis, so it is also called Lutz disease. Later, it is known as claudication follicular keratosis and parafolliculosis. Keratinizing papules mainly appear on the side of the neck and on the back of the neck, with a lamely circular arrangement. The course is long and slow. There are those who have resolved themselves after many years.
