UNASSIGNED: History and clinical findings: We report the case of a 60-year-old @entity1 with localized erythema and @entity4 , caused by an @entity737 ( @entity737 ). Examination: An @entity281 could be excluded by clinical examination, para clinical parameters and clinical chemistry. The histologic examination was indicative for @entity56 . Patch test was negative but @entity3406 sensitization was seen by lymphocyte transformation test and @entity3406 could be measured in the pacemaker eluate. Treatment and Course: Based on the synopsis of negative patch testing, the @entity56 resembling histology and the corresponding in vitro analysis, the assumed cause for the @entity1909 is a contact @entity566 to @entity3406 as pacemaker component. After explantation, complete restitution of the skin could be observed. Conclusions: Unusual skin reactions in @entity1 with cardiac pacemakers are mostly referred to as "Pacemaker @entity1909 ". There are various potential causes: first, an @entity281 needs to be excluded. Then, the possibility of both "pressure damage" caused by the pacemaker and the mostly symptom free "pacemaker erythema with @entity8721 " - synonym "post implantation erythema" - needs to be considered. When suspecting an incompatibility of the implant, further allergologic testing is required. Often, the removal of the pacemaker is inevitable.
