title: Neuroendocrine carcinoma of the larynx with subcutaneous and intramuscular metastases: a case report.
abstract: Neuroendocrine carcinomas have become increasingly recognized as more reports are emerging to describe these rare tumors. Primary sites include the lung, liver, throat, and other organs. Laryngeal neuroendocrine carcinomas are relatively rare, and the subtypes as well as the prognoses are quite different in most cases. Metastases to the liver, lungs and other parts are common. However, metastases to subcutaneous tissues or muscles have been rarely reported. We report a case of a neuroendocrine carcinoma of the larynx with subcutaneous and muscle metastases.
