Epidermolysis bullosa acquisita (EBA) is an acquired subepidermal blistering disease associated with autoantibodies against type VII collagen. The classical or mechanobullous form of EBA is characterized by skin fragility, trauma-induced blisters and erosions with mild mucous membrane involvement and healing with scars. Furthermore, bullous-pemphigoid-like and cicatricial pemphigoid-like features have been described. We report a patient who developed a bullous skin disease with upper airway obstruction requiring tracheotomy. The diagnosis of EBA was established by immunoblot, showing a band at 290 kD (collagen VII), and NaCl-split skin immunofluorescence (IgG deposition at the floor of the split). This case presented with clinical features of both bullous pemphigoid and cicatricial pemphigoid which to our knowledge is the first report of such a combination in EBA. The patient also presented tracheal involvement that has never been described either.
We report the case of a 74-year-old woman with recurrent episodes of symmetrical congestion and erythema in the distal lower legs causing a burning distress. Laboratory and clinical investigations revealed an underlying myeloproliferative disorder. The cutaneous symptoms were atypical of erythromelalgia. Salicylates and treatment of the underlying polycythemia were able to eliminate the skin lesions but not entirely suppress the subjective discomfort.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
