Objective
To assess the microvascular density (MVD) in juvenile nasopharyngeal angiofibroma (JNA) with CD34 immunostaining and evaluate its relationship with clinico-demographic features.
Methods
This prospective study included patients with JNA undergoing endoscopic excision. The histopathological specimen was stained using CD-34 antibodies to calculate MVD. MVD and clinico-demographic features were correlated.
Results
The study included 12 patients with a median age of 15.5 years. The mean MVD was 39 vessels/high power field (range 5 to 151 vessels). MVD was significantly associated only with the volume of tumour (r = 0.65, p = 0.02). The recurrence occurred in one patient with an MVD of 107. The median follow-up was 38 months.
Conclusion
MVD is significantly associated with tumour volume in JNA, which implies a robust role of angiogenesis in the pathology of the tumour. Also, higher MVD may be a risk factor for recurrence.
