Acne necroticans varioliformis
In acne necroticans varioliformis
multiple pruritic inflammatory papules and papulopustules
are present on the scalp, particularly the frontal and
forehead areas, which rupture and cause erosions,
crusts, and scarring. Cicatricial alopecia may be
present. It is a chronic recurrent comdition. The cause is unclear,
infectious or inflammatory. Scratching the pruritic papules may also be a contributing factor. It causes cribiform scars and bald patches on the forehead and along the hairline. It occurs primarily in men. Biopsies reveal a lymphocytic inflammatory infiltrate, followed by neutrophils in later stages.
