Acrocyanosis: The Least Known Acrosyndrome Revisited With a Dermatologic Perspective

Abstract

Conclusions: Although acrocyanosis is the least known and the least studied acrosyndrome, it is increasingly more commonly confronted in the COVID-19 era. The diagnosis still largely relies on clinical findings. Accordingly, it has become a growing necessity for a dermatologist to remain updated on this peculiar disorder and be able to differentiate acrocyanosis from clinically similar cold-induced or cold-exacerbated acrosyndromes. Acrocyanosis is still misdiagnosed, underdiagnosed, underreported, and undertreated by the dermatology community.
