[Digital arteritis preceding the diagnosis of a malignant B cell lymphoma].

We report the case of a young smoker woman who developed a severe acrosyndrome of rapid onset, involving both hands except the thumbs. The angiography showed digital arteritis. Antinuclear antibodies were present at high level. Three months later, a large B cell lymphoma was diagnosed. Complete remission was achieved, but the acrosyndrome persisted with only partial improvement. The antinuclear antibodies disappeared. The paraneoplastic nature of the acrosyndrome is discussed.
