Necrotizing Fasciitis Associated with Hailey-Hailey Disease: A Rare Case

Necrotizing fasciitis (NF) is a rare and life-threatening infection of soft tissue characterised by rapid and extensive destruction of the skin, subcutaneous fat, and fascia. Early diagnosis of NF is challenging, and it can be very difficult to distinguish NF from other infectious diseases of skin and subcutaneous tissue. Imaging studies and laboratory investigations are crucial diagnostic means for NF. We diagnosed a case of NF with multiple organ dysfunction and septic shock, and this is the first case of NF associated with Hailey-Hailey disease (HHD) to our knowledge. Clinicians should be alert to signs and symptoms of NF in HHD and other skin diseases with damaged skin barrier function such as pemphigus, pemphigoid, and all kinds of ulcers, especially in diabetic and immunosuppressed patients. Key Words: Necrotizing fasciitis, Genodermatosis, Hailey-Hailey disease.
