Abstract

Malignant sinonasal tumors are rare and account for 1% of all neoplasms. Most of these carcinomas are poorly differentiated or undifferentiated tumors. Due to overlapping features, both young and experienced physicians encounter difficulties in their diagnosis. We present 2 cases of 2 tumors of the sinonasal tract, which belong to small round blue cell tumors: sinonasal small cell neuroendocrine tumor and esthesioneuroblastoma.
