title: Sinonasal undifferentiated carcinoma invading the orbit.
abstract: Sinonasal undifferentiated carcinoma (SNUC) is an infrequent tumor described by Frierson et al. in 1986. Since its initial description, fewer than 100 patients have been reported. We present a case of a SNUC invading the orbit in a 57-year-old woman, for which the findings are documented by CT scan, light and electron microscopy.
