Raynaud's Phenomenon: Beware of Cancers!

Raynaud's phenomenon (RP) is a frequent syndrome and often indicative of connectivitis or hemopathy. The association with solid cancers is exceptional. We report the observation of a patient hospitalized for severe RP whose etiological assessment revealed the existence of colorectal cancer. We discuss, through this clinical case, the potential physiopathological links and underline the importance of looking for underlying cancer in the face of severe, refractory to treatment, or atypical RP.
