The development of vesiculo-bullous lesions may be associated with a high morbidity, hence they warrant an urgent investigation, including a skin biopsy to identify the diagnosis and initiate prompt treatment. With…
The past five years have been busier than usual for the Churg-Strauss syndrome. It was renamed eosinophilic granulomatosis with polyangiitis (EGPA).1 Longitudinal cohorts totaling 484 patients—approximately as many as all previous series combined—were described.2,3 A proposal was advanced to remove and rename a subset in which vasculitis may not be present.4 And shortly after the…
As a manifestation of hyperuricemia, inflammatory bullous lesions have rarely been described in the past century. A more classic presentation of hyperuricemia is acute inflammatory gouty arthritis, characterized by the deposition of monosodium urate crystals. Other complications of chronic untreated hyperuricemia may include polyarticular arthritis, tophus formation and possible chronic destructive lesions of the bone,…
Eosinophilic granulomatosis with polyangiitis (EGPA), also known as Churg-Strauss syndrome or allergic granulomatosis and angiitis, is a rare small- and medium-vessel vasculitis. This disease was first described by American pathologists Jacob Churg and Lotte Strauss in 1951.1 Although the vasculitis is often not apparent in the initial phases of the disease, EGPA can affect any…
