MALDONADO, Génessis  and  RIOS, Carlos. Raynaud's phenomenon associated with nitric acid: Case report. Rev.Colomb.Reumatol. [online]. 2017, vol.24, n.1, pp.48-53. ISSN 0121-8123.  https://doi.org/10.1016/j.rcreu.2016.08.002.

The Raynaud phenomenon is a clinical disorder, characterized by episodic attacks of vasospasm of peripheral arteries and arterioles, causing tissue ischemia of distal portions of the body, such as hands and feet, causing changes in skin color such as pallor, cyanosis and hyperemia. The occurrence of the Raynaud phenomenon in people who handle organic sol vents or vibratory tools has been associated for a long time, and it has even been described that the solvents may be triggering some immune diseases such as scleroderma, however, as far as we know there are reports of exposure of chemical compounds used in metallurgy, such as nitric acid and the development of scleroderma-spectrum diseases. This article presents a clinical case related to the appearance of Raynaud s phenomenon against exposure to chemical compounds used in metallurgy, especially nitric acid.

Keywords : Raynaud's phenomenon; Nitric acid; Organic solvents; Capillaroscopy; Scleroderma spectrum disorders; Scleroderma pattern.
