Аннотация
BACKGROUND: Juvenile nasopharyngeal angiofibroma (JNA) has witnessed a four-fold increase in the incidence at our facility in the current decade as compared to the 1980s. With high global incidence of human pappilloma virus (HPV) related oropharyngeal cancer in India, we hypothesize its implication in JNA as it has not yet been reported.
METHODS: Clinico-Surgical variables of 6 patients of JNA were included for correlation and their tissue samples were subjected to western blotting (WB), polymerase chain reaction and immunoflorescence to demonstrate a definite association with HPV. In addition 6 control samples (adenoids) underwent WB analysis.
OBSERVATIONS: A universal presence of HPV with JNA is novel 'discovery' and has suggested a possibility of a definite association. Only a single case suggested weak infection. None of the controls suggested infection, thus ruling out the presence of HPV in nasopharynx of normal population.
INTERPRETATION: With the dawn of this definite association, no specific conclusions can yet be drawn but a whole plethora of questions have emerged with our novel 'discovery'.
