NEUROENDOCRINE CARCINOMA AS SINONASAL MALIGNANCY

Sinonasal neuroendocrine carcinoma presenting as a nasopharyngeal mass.

Sinonasal neuroendocrine carcinoma: a case report.

Neuroendocrine carcinoma (NEC) is rare. We report a case of probable sinonasal NEC in a 73-year-old man who had presented with a history of right nasal obstruction, nasal discharge, and recurrent epistaxis. On examination, a red, friable, gelatinous, polypoid mass with a tendency to bleed was seen in the right nasal cavity. Computed tomography revealed that the lesion was confined to the right ...

Multimodality treatment for sinonasal neuroendocrine carcinoma.

BACKGROUND Neuroendocrine carcinoma (NEC) of the paranasal sinuses is rare, accounting for 5% of sinonasal malignancies. The purpose of this study was to assess prognostic factors and survival rates for sinonasal NEC. METHODS A retrospective review of patients with NEC treated from 1990 to 2004 was performed. Patient demographics, TNM classification, treatment modality, recurrences, and survi...

Esthesioneuroblastoma, Neuroendocrine Carcinoma, and Sinonasal Undifferentiated Carcinoma: Differentiation in Diagnosis and Treatment

Introduction Malignant sinonasal tumors comprise less than 1% of all neoplasms. A wide variety of tumors occurring primarily in this site can present with an undifferentiated or poorly differentiated morphology. Among them are esthesioneuroblastomas, sinonasal undifferentiated carcinomas, and neuroendocrine carcinomas. Objectives We will discuss diagnostic strategies, recent advances in immunoh...
