A case of primary cutaneous senile EBV-related diffuse large B-cell lymphoma.

Epstein-Barr virus is known to be associated with the development of lymphomas in immunosuppressed patients. Recently, age-related immune impairment was recognized as a predisposing factor in the development of Epstein-Barr virus-driven lymphoproliferative processes in elderly patients. We describe the case of an otherwise healthy 84-year-old lady who developed a solitary primary cutaneous diffuse B-cell lymphoma on her leg in which the majority of the malignant cells had Epstein barr early RNA (EBER) and late membrane protein-1 expression, with in situ hybridization and immunohistochemistry, respectively.
