[Abdominal pain, indigestion and eosinophilia].

A 56 years old swiss man suffers of recurrent abdominal cramps with episodes of diarrhea and profuse expectorations. The routine laboratory shows principally a massive eosinophilia and elevated IgE in peripheral blood. After excluding the most frequent causes of eosinophilia, further laboratory investigations shows increased levels antinuclear and anti-SSA antibodies, elevated IgG4, increased pancreatic amylase and intestinal eosinophilia. We consider two etiologies: the hypereosinophilic syndrome, diagnostic of exclusion, and the autoimmune pancreatitis. Although we have not sufficient arguments in favour of an autoimmune pancreatitis, these two entities present some similar points.
