[Waldenström's hyperglobulinemic purpura. Apropos of a case].

The authors report the case of a thirteen-year-old girl who developed clinical manifestations suggestive of Schönlein-Henoch purpura and in whom biologic tests outruled this condition and led to the diagnosis of Waldenström hyperglobulinemic purpura. Investigations illustrated the immunologic nature of this disease, outruled an underlying disease and established the diagnosis of primary hyperglobulinemic purpura.
