Sinonasal undifferentiated carcinoma invading the orbit.
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.
