title: Lobular panniculitis due to Borrelia burgdorferi infection mimicking subcutaneous panniculitis-like T-cell lymphoma.
abstract: The authors present an unusual case of lobular panniculitis caused by Borrelia burgdorferi senso latu infection in a 56-year-old man. It presented clinically as a solitary subcutaneous nodule. Histopathologically, the lesion resembled subcutaneous panniculitis-like T-cell lymphoma by manifesting atypically appearing lymphocytes with cytotoxic phenotype. B. burgdorferi etiology was proven by positive polymerase chain reaction and serology and positive response to antibiotics.
