Acne inversa is a chronic inflammatory disorder of sebaceous follicles and terminal hair follicles and is one type of acne diseases. The pathogenesis of acne inversa is identical with that of the other types: Hyperkeratosis of the follicular infundibulum leads to a comedo. Bacterial infections result in a rupture of the follicular canal followed by a granulomatous inflammatory reaction with abscesses, panniculitis and draining sinuses.
