Abstract
Cat scratch disease has been reported very rarely in cardiac transplant recipients. In a review of 1073 episodes of infection in 620 heart transplant patients over a 16 year period, only one case of infection secondary to Bartonella henselae was documented. Another case of hepatosplenic bacillary angiomatosis from B. henselae was reported 2 decades ago in a heart transplant recipient who had presented with fevers of unknown origin. Although the typical clinical manifestation is that of a skin lesion accompanied with lymphadenopathy, cat scratch disease may present with persistent fevers without a clinically overt infective focus in immunosuppressed individuals. Moreover, more than one disease process may coexist in immunocompromised hosts. While the lymphadenopathy in our patient was secondary to Cat scratch disease, interestingly, the adjacent skin lesion that was thought to represent unhealed site of inoculation of Bartonella was diagnosed as squamous cell carcinoma.
