ABSTRACT
This chapter provides a case study of a 32-year-old carpenter who presents with a 3-month history of an itchy and ‘stinging’ eruption. He had already been treated with a course of anti-scabies topical therapy and had used a moderately potent topical steroid in combination with antihistamine for 4 weeks with no benefit. He has no significant past medical history and is on no other medication. He comments that the eruption occurs in crops, with small fluid-filled blisters appearing in very itchy patches. He has pale, freckled skin, and a symmetrical but patchy eruption, with erythematous and eczematous epidermal change studded with excoriated erosions and crusted papules, clustered particularly over his elbows, buttocks and shoulders. He has no mucosal lesions and no evidence of scabies burrows. The remainder of his physical examination is normal. Dermatitis herpetiformis is an autoimmune blistering disease and manifestation of gluten sensitive enteropathy.
