Background: Several studies have indicated an eti-Schneiderian papillomata. The classification of ologic role for viruses in the development of sinonasal inverted the latter lesions is somewhat confusing in the papillomata (IP). A recent report demonstrates a strong relationship (65%) between Epstein-Barr virus (EBV) and these lesions literature, owing to the varied descriptors that using polymerase chain reaction (PCR) analysis.
are used to relate their microscopic appearance.
Methods: The present study analyzes a series of paraffin-Fungiform papillomata (FP, also described as embedded tissues, comprising 25 surgically resected IPs and everted or exophytic squamous) occur almost exfour fungiform papillomata (FP) for the presence of EBV using a clusively on the nasal septum, whereas inverted sensitive in situ hybridization (ISH) assay and PCR.
Results: None of the specimens examined showed evidence papillomata (IP, also referred to as Schneiderian, of EBV infection by ISH, and only two papillomata (one sinonasal transitional-cell, or Ringertz) involve the lateral IP and one FP) gave positive reactions for EBV using PCR.
