Erythema gyratum repens-like eruption in a patient with epidermolysis bullosa acquisita associated with ulcerative colitis.

SIR, Epidermolysisbullosaacquisita (EBA) is an acquired auto-immune bullous disease of the skin and mucous membranes characterized by IgG autoantibodies to type VII collagen, the main constituent of the anchoring fibrils of the dermal– epidermal juction. Inflammatory bowel diseases (IBD) may be associated with autoimmunity to type VII collagen. Erythema gyratumrepens (EGR), an obligate paraneoplastic syndrome, may occur in patients with pemphigoid diseases. To the best of our knowledge, EGR has not been previously described in EBA. We report a most unusual clinical manifestation of EGR-like lesions in a patient with EBA and ulcerative colitis (UC).
