PARRA-IZQUIERDO, Viviana et al. Blue finger syndrome: Case reports. Rev.Colomb.Reumatol. [online]. 2018, vol.25, n.4, pp.292-297. ISSN 0121-8123.  https://doi.org/10.1016/j.rcreu.2017.09.003.

Blue finger syndrome (BFS), usually noted by the violet or blue coloration of one or more fingers, may be the first manifestation of several diseases. These may present with alterations directly on the fingers or be the expression of systemic diseases. The most common pathophysiological causes are thrombosis, embolism, severe vasoconstriction, or vasculature involvement that may be inflammatory or non-inflammatory.

A description is presented of 5 cases of BFS, where the emphasis is placed on the importance of early diagnosis. The concept of evaluation and approach as a medical emergency is also stressed, because depending on this, it could reduce irreversible complications, such as necrosis and/or amputation.
