Infection of lymphocytes with the Epstein-Barr virus (EBV) is a well-documented risk factor for developing lymphoma. The incidence of EBV positivity in lymphoma depends on the subtype and can range from 10% in diffuse large B-cell lymphoma (DLBCL) to 100% in endemic Burkitt lymphoma (BL), (Shannon-Lowe and Rickinson, Front Oncol 9:713, 2019). However, in most cases, EBV infection remains unnoticed until diagnosis of lymphoma is made. EBV seropositivity is present in > 90% of the world's population. Although mostly asymptomatic, in some cases, EBV can cause clinical symptoms, the most common of which are fever, lymphadenopathy and pharyngitis in infectious mononucleosis. Less common presentations include lymphomatoid granulomatosis and mucocutaneous ulcer. Here we report two cases of patients, who were initially diagnosed with localized EBV infection and reactive B-cell proliferation. After B-cell-directed treatment, both patients developed overt lymphoma, in one case classical Hodgkin's lymphoma (cHL) and in the other case angioimmunoblastic T-cell lymphoma (AITL).

Melanie Ward Myla D Goldman

Continuum (Minneap Minn) 2022 Aug;28(4):988-1005

Purpose Of Review: This article provides an overview of genetic, environmental, and lifestyle risk factors affecting the disease course of multiple sclerosis (MS) and reviews the pathophysiologic characteristics of both relapsing and progressive MS.

Recent Findings: The prevalence of MS has increased in recent decades, and costs of care for patients with MS have risen dramatically. Black, Asian, and Hispanic individuals may be at risk for more severe MS-related disability. Read More

Catastrophic antiphospholipid syndrome (CAPS) is a severe variant of antiphospholipid syndrome associated with multiorgan thrombosis in a short term. We present the case of a 14-year-old immunocompetent girl who developed renal, intestinal, and pulmonary infarction; thrombocytopenia; and hemolytic anemia within 1 week. She was diagnosed with thrombotic microangiopathy. Read More

Epstein-Barr virus (EBV) is a double-stranded DNA virus of the Herpesviridae family. This virus preferentially infects human primary B cells and persists in the human B cell compartment for a lifetime. Latent EBV infection can lead to the development of different types of lymphomas as well as carcinomas such as nasopharyngeal and gastric carcinoma in immunocompetent and immunocompromised patients.

Rom J Ophthalmol 2022 Apr-Jun;66(2):198-208

Department of Ophthalmology, "Dr. Victor Gomoiu" Children's Hospital, Bucharest, Romania.

The diagnosis of bilateral panuveitis was made in a 9-year-old girl who was referred to our hospital for blurred vision accompanied by periorbital and abdominal pain. Endothelial dusting, vitreous haze and optic nerve edema were deemed as signs of involvement of all segments of the eye. The bloodwork results were suggestive of infectious uveitis, with elevated inflammatory markers and the patient was treated with IV antibiotics. Read More
