Acne inversa, also known as hidradenitis suppurativa, is a chronic inflammatory disease of the hair follicles whose characteristic features include draining sinuses, painful skin abscesses, and disfiguring scars. Manifestations typically appear after puberty. Familial acne inversa is genetically heterogeneous (summary by Wang et al., 2010).
