This binding facilitates the interaction of viral glycoprotein gp42 with B-cell major histocompatibility complex (MHC) class II, thereby triggering fusion of the viral envelope with the B-cell plasma membrane and allowing EBV deoxyribonucleic acid (DNA) entry into the B-cell. EBV preferentially infects B-cells through binding of viral envelope glycoprotein gp350/220 to CD21 (complement receptor type 2) on B-cells. As EBVMCU is not currently included in the 2008 WHO classification of lymphoproliferative disorders and no evidence-based guidelines or expert opinions have been proposed to guide therapy, this case report and systematic review provides a foundation on which to guide therapeutic decisions.Įpstein–Barr virus (EBV), also known as human herpes virus 4, is one of eight viruses within the human herpes virus family that infects humans and is directly transferred between humans through saliva. CD20- and CD30-directed antibody therapy, local radiation therapy, local surgical excision, systemic chemotherapy, and a combination of these therapies have all been successfully used to treat EBVMCU with high rates of durable clinical remission. We suggest that although many patients with EBVMCU experience a self-limited course, for others EBVMCU can be a debilitating, persistent disorder that requires aggressive therapy to prevent disease progression. She was successfully treated with local external beam radiation therapy of 30 Gy in 15 fractions, with duration of response of at least 6 months.

Her disease relapsed within 3 months and continued to progress and cause significant morbidity. Case presentationĪ forty-nine year old woman presented with painful and debilitating multifocal oral EBVMCU that initially responded to four weekly doses of rituximab. We now systematically review all published cases of EBVMCU and detail a case of aggressive and progressive EBVMCU, including diagnostic and management challenges, as well as successful treatment with radiation therapy. Since that publication, additional cases have been reported that describe a more heterogeneous clinical course, often requiring aggressive therapy.

The first case series that described EBVMCU suggested that EBVMCU is generally self-limited and is likely to resolve without treatment. This disorder is likely under reported, as it was only first defined in 2010 and shares histological features with other B-cell proliferative neoplasms. Local attenuation of immunosurveillance associated with iatrogenic immunosuppressant use, primary immunodeficiency, or age-associated immunosenescence has been implicated as a predisposing factor. Epstein–Barr virus-positive mucocutaneous ulcer (EBVMCU) is a recently recognized B cell lymphoproliferative disorder that is driven by latent EBV infection and causes discrete ulcerations in the oropharynx, gastrointestinal tract, and skin.
