The article describes a clinical case of monozygotic twins with hypertrophy of the organs of the lymphopharyngeal ring. The examination revealed IgG to the Epstein–Barr virus capsid antigen in both patients. One twin had Epstein–Barr virus DNA in the sample from the oropharynx. It was this child who had complaints typical of patients with adenoid vegetation, and he required surgical treatment (endoscopic shaver adenotomy and radio wave bilateral tonsillotomy). At the time of the initial examination and in the absence of complaints the second twin revealed no DNA of Epstein–Barr virus in the oropharynx. This patient was diagnosed with adenoids of 1–2 degree. Due to the complaints of the second twin that appeared during the following year of observation, with previously negative results on active Epstein–Barr virus markers served as the reason for a repeated specific laboratory examination. Epstein-Barr virus DNA was found in a sample from this child’s oropharynx. This case using the twin control method by partner enabled us to demonstrate the significance of Epstein–Barr virus in the pathogenesis and clinic manifestations of chronic diseases of the lymphopharyngeal ring organs in children.
