2008
Cutaneous Epstein-Barr virus (EBV)-associated B-cell lymphoma (EBVBL) in non-immunocompromised patients is very rare. Here, we report a case of cutaneous EBVBL in a 72-year-old Japanese woman without any signs of immunosuppression. She showed repeated high fever and skin eruptions on the face, limbs and palms. Histological diagnosis was diffuse large B-cell lymphoma. EBV infection was detected by in situ hybridization and Southern blotting. Immunostaining for viral proteins showed the patient to be positive for latent membrane protein 1 (LMP-1) and negative for Epstein-Barr virus nuclear antigen-1 (EBNA-2), indicating that a type II latency EBV infection pattern.
