Dermatitis herpetiformis (DH) is the cutaneous manifestation of coeliac disease. It represents a distinct clinical presentation in which the systemic autoimmune process drives skin disease, and management must address both dimensions.
The patient has dermatitis herpetiformis — the cutaneous expression of coeliac disease. Diagnosis is dermatology-led and confirmed by skin biopsy. This presentation calls for a specific treatment strategy that goes beyond standard coeliac management to address the active skin manifestation.
The cornerstone of management is a lifelong dietary intervention, which underpins long-term disease control. In addition, a short-term pharmacologic component is used specifically to manage the cutaneous manifestation.
The full protocol — including the specific pharmacologic agent, its role relative to dietary therapy, and the complete clinical algorithm — is available in the structured regimen below.
