Abstract
Since the early transcript by Raynaud and Trousseau, there has been wide acceptance of the association of occult malignancy and peripheral vascular disease. Recently, there have been a few case reports of acute onset monophasic digital ischemia heralding an occult malignancy. It appears that the site and tumor types seem unimportant in the development of ischemia; tumor resection however, usually results in rapid improvement of the affected digit. The mechanism remains to be established.
