Abstract

We report the first patient (a 13-year-old girl) with a sinonasal low-grade non-intestinal-type adenocarcinoma showing aberrant CDX2 expression both within morular areas and in the tubular component and demonstrate for the first time a SYN2-PPARG gene fusion in this tumor type. The tumor arose from the nasal septum and had not spread beyond the nasal cavity.

Keywords
