title: Pemphigus vulgaris as a possible cause of protein-losing gastroenteropathy: a case report.
abstract: We present a case of pemphigus vulgaris (PV) accompanied with protein-losing gastroenteropathy (PLE). A 9-year-old girl developed multiple oral ulcerations and erosions. She was first treated with oral antibiotics and a topical steroid without improvement. Laboratory data showed eosinophilia (absolute eosinophil count 1.08 x 10(9)/L) and hypoproteinemia (total serum protein 3.9 g/dL, albumin 2.2 g/dL). A biopsy specimen from the ileum showed intense eosinophil infiltration and albumin scintigraphy demonstrated protein exduation from the same site. Endoscopic examination of the oesophagus showed multiple ulcerations and erosions, and biopsy specimen showed eosinophilic spongiosis and immunohistologic staining demonstrated deposits of IgG and C3 in the intercellular space. Antidesmoglein-3 antibody elevated, she was diagnosed as PV complicated with PLE. Immunofluorescence study of a biopsy specimen from the terminal ileum showed no significant immunoglobulin or complement deposition, and autoantibody against intestinal mucosa was unclear in this case. Gastrointestinal evaluations should be considered in patients with hypoproteinemia associated with PV.
