NEUROENDOCRINE DIFFERENTIATION AND CELL PROLIFERATION IN ORAL AND OROPHARYNGEAL SQUAMOUS CELL CARCINOMA

Objective Squamous cell carcinoma (SCC) of the head and neck region with neuroendocrine differentiation are rare neoplasms. These tumors can be poorly differentiated and usually have tendency for aggressive clinical behavior and propensity for both regional and distant metastasis. Their diagnosis is based on morphology and confirmation of origin by immunohistochemistry. The purpose of this study was to investigate the neuroendocrine...
