title: [Paradoxical aspects of acrocyanosis and its pathogenesis].
abstract: First described by Crocq (1896) the clinical pattern of acrocyanosis is well known and its diagnosis is easy but acrocyanosis is a nosological frame with multiple aspects and a constitutional basis of microvasculotissular dysregulation. Acrocyanosis is made of capillarovenular hypotonia and stasis with a large and permanent opening of arteriovenous glomic anastomosis (J.F. Merlen, 1952).
