[Conjunctival mass as the first manifestation of Epstein Barr virus infection]

The Epstein Barr virus is an infectious disease with a high worldwide prevalence, which can present multiple systemic manifestations. The ophthalmological findings are the least frequent and nonspe cific and, therefore, its diagnosis is complicated and delayed; however, it should always be considered as a diagnostic possibility in the presence of atypical ocular and periocular inflammatory clinical pictures.

To describe the clinical case of a patient with the presence of a conjunctival mass as the first finding in Epstein Barr virus infection.

A 4-year-old boy with a 4-day history of left upper eyelid edema and ptosis associated with a large, fast-growing, elevated, painful, and salmon-colored upper bulbar conjunctival mass with extension to the upper fornix associated with bilateral cervical and inguinal lymphadenopathy. Initially, a lymphoproliferative disorder was suspected, with blood count with lymphocytosis and atypical lymphocytes, elevated lactate dehydro genase, peripheral blood smear with an increase in white blood cells and some atypical lymphocytes, bone marrow aspirate with a predominance of granulocytes and predominantly CD8-positive T lym phocytes and an increase in Gamma-Delta T lymphocytes. The orbit CT scan showed thickening of the left upper eyelid with peripheral enhancement and the abdominal CT scan showed splenomegaly. Biopsy confirmed chronic Epstein Barr virus infection with positive IgM and indeterminate IgG anti bodies. Symptomatic management was indicated with satisfactory evolution and complete resolution of the conjunctival lesion and lymphadenopathy.

Epstein Barr virus infection should be considered as a possible diagnosis in atypical ocular and periocular inflammatory manifestations in the pediatric population.
