High Suspicion of Bacillary Angiomatosis in a Kidney Transplant Recipient: A Difficult Way to Diagnose—Case Report

Bacillary angiomatosis is an infection caused by Bartonella, which has first been described in human immunodeficiency virus (HIV)-infected patients. We report an unusually located lesion, in a totally asymptomatic kidney transplant recipient. The diagnosis was strongly suggested based on the iconography and our histological analysis, but was not confirmed using polymerase chain reaction (PCR) and immunohistochemical studies. We illustrate our difficult way to the diagnosis as well as the course of the disease and our therapeutic strategy.
