[True and false acrocyanoses]. / Vraies et fausses acrocyanoses.

ABSTRACT

Acrocyanosis is an acrosyndrome frequently found among adolescent or young women. Four clinical symptoms are necessary and sufficient to establish the diagnosis permanent and painless cyanosis of extremities, local hypothermia, permanent sweatiness, and elastic infiltration of the integument. In practice, only one investigation is useful but not indispensable capillaroscopy which visualizes capillarovenular stasis. Numerous clinical forms have been described, but they are exceptions, but for supramalleolar erythrocyanosis. Treatment is mainly preventive protection against cold. Two conditions can be regarded as false acrocyanosis acrorhigosis and acroiodesis.
