A Rare Case of Locally Advanced Recurrent Neuroendocrine Tumour of Neck Salvaged by a Radical Surgical Approach.

Neuroendocrine tumours of head and neck are rare neoplasms and even more rare are those of cutaneous adenoid cystic carcinoma with neuroendocrine differentiation. Virtually every known variant of neoplasia with neuroendocrine differentiation can arise in complex structures of head and neck (Mills in Endocr Pathol 7(4):329-343. doi:10.1007/BF02739841) [1]. Such tumours are usually non functional, locally aggressive and may spread to lymph nodes or lungs. They are diagnosed by histopathology, immunohistochemistry and radionuclide imaging. When these tumours involve the carotid artery, they pose challenges in the surgical management.
