[Correspondence] Coeliac disease and dermatitis herpetiformis

Potential coeliac disease is characterised by the presence of serological and genetic markers of coeliac di-sease with little or no damage to the mucosa of the small intestine.1 Potential coeliac disease is a growing clinical entity, accounting for 10–20% of the total number of coeliac disease cases.2,3 In their excellent Seminar, Benjamin Lebwohl and colleagues4 do not give adequate attention to this increasingly observed disorder. Patients with potential coeliac disease can manifest with gastrointestinal or extraintestinal symptoms, or both, or be completely asymptomatic.
