Life‐threatening acute pulmonary haemorrhage in primary Sjögren's syndrome with cryoglobulinaemia

We describe a woman with primary Sjogren's syndrome who presented with an acute pulmonary‐renal syndrome resulting from cryoglobulinaemic vasculitis. Pulmonary manifestations of Sjogren's syndrome are relatively common, whereas overt pulmonary complications of cryoglobulinaemia are rare. Pulmonary haemorrhage is rare in either disorder. The combination of Sjogren's syndrome, cryoglobulinaemia, and acute pulmonary haemorrhage has not been previously reported.
