Abstract: Infectious mononucleosis (IM) is Epstein-Barr virus-associated and self-limited lymphoproliferative disorder. The histopathologic
features of the nasopharynx in IM are rarely described. In this report, we described a patient of IM with atypical T-cell proliferation in the
nasopharynx. In-situ hybridization for EBV-encoded RNA with immunostaining against CD20 was used for evaluation of EBV infection. The
histopathologic features of IM could mimic malignant T-cell lymphoma. It should be differentiate reactive T-cell lymphoproliferation from
malignant lymphoma in the nasopharynx. (IJCP1208012).
