Small cell neuroendocrine carcinoma of the nasal cavity and paranasal sinuses: a rare case.

Objective: We report a rare case of small cell neuroendocrine carcinoma of the nasal cavity and paranasal sinuses with intracranial extension, and discuss the management of this rare tumour. Results: Small cell neuroendocrine carcinoma involving the nasal cavity and paranasal sinuses with intracranial extension may be treated successfully with surgery alone, without development of local recurrence. Conclusion: Small cell neuroendocrine carcinoma is a locally aggressive tumour with a high rate of recurrence. Early and aggressive surgical excision with or without radiotherapy or chemotherapy can improve a patient's outcome and prognosis. Regular follow up is needed to detect any local or distant recurrence.
