Neonatal inflammatory skin and bowel disease is a rare, life-threatening, autoinflammatory syndrome with immune deficiency disorder characterized by early-onset, life-long inflammation, affecting the skin and bowel, associated with recurrent infections. Patients present perioral and perianal psoriasiform erythema and papular eruption with pustules, failure to thrive associated with chronic malabsorptive diarrhea, intercurrent gastrointestinal infections and feeding troubles, as well as absent, short or broken hair and trichomegaly. Recurrent cutaneous and pulmonary infections lead to recurrent blepharitis, otitis externa and bronchiolitis.
Features include common findings: Blepharitis, Onychogryphosis, Psoriasiform dermatitis, and Recurrent bacterial skin infections and others; and sometimes findings: Thickened left heart wall (left ventricular hypertrophy).
