Abstract
BACKGROUND: Epidermolysis bullosa acquisita (EBA) is a rare auto-immune blistering disease. We report a case of Brunsting-Perry pemphigoid diagnosed by immunoelectron microscopy (IEM).
PATIENTS AND METHODS: A 46-year-old man presented very pruriginous vesicles on the face and neck present for 6 years and which were difficult to diagnose and treat. The appearance of atrophic scars and milium cycts evoked EBA, which was confirmed at IEM. Due to limited involvement of the face and the neck, we conclude on EBA of the Brunsting-Perry pemphigoid variant. Treatment with dapsone produced a favorable outcome.
DISCUSSION: Diagnosis of EBA is often difficult. In a case review, Asfour et al. collated 60 cases of Brunsting-Perry pemphigoid. These patients had either anti-collagen VII or anti-BP180 and anti-BP230 antibodies. IEM showed cleavage either under the lamina densa or within the lamina lucida, suggesting that Brunsting-Perry pemphigoid is a subtype of EBA or bullous pemphigoid (BP), depending on the paraclinical elements, and localized to the head and neck. The majority of EBA-like cases required systemic therapy, whereas in the presence of BP antibodies, topical corticosteroids were effective.
CONCLUSION: We report a case of EBA of the Brunsting-Perry pemphigoid type, diagnosed by IEM after 6 years of progression. We highlight the diagnostic and nosological difficulties of Brunsting-Perry pemphigoid. Classification of this dermatosis as a subtype of EBA or BP may enable effective adaptation of therapeutic management, which has not as yet been coded.
