Abstract

Abstract: Hydrophilic polymer‐coated devices have been increasingly utilized for various endovascular procedures, however not been without adverse effects. We report two cases of subacute cutaneous lesions on the neck encountered in our dermatology clinic. Histopathologic findings were significant for a nodular aggregate of epithelioid histiocytes and lymphocytes with numerous foreign body giant cells in the dermis. The granulomatous infiltrate was associated with an amorphous basophilic non‐polarizable material. Further chart review reveals both patients receiving a central venous procedure in the past, thus attributing the hydrophilic polymers as the likely source of the foreign material found at the insertion site. Our cases contrast to the more commonly reported distal embolization by these hydrophilic polymer layers. We suspect the incidence of retained hydrophilic polymer at the site of prior endovascular procedures may be underreported in the literature with the more inconspicuous presentations. Therefore, retained foreign material should be considered by both treating physicians and dermatopathologists in presenting cases of lesions that occur at common sites of endovascular procedures.
