title: Unique presentation of adenoid cystic carcinoma in postcricoid region: a case report and review of the literature.
abstract: Malignant tumors of minor salivary glands are uncommon, representing only 2-4% of all head and neck malignancies. In the larynx, minor salivary gland tumors rarely occur and constitute less than 1% of laryngeal tumors. Most of the minor salivary gland tumors arise in the subglottis; however, they can also occur in the supraglottis in the false vocal cords, aryepiglottic folds, and caudal aspect of the epiglottis. The most common type of malignant minor salivary gland tumor is adenoid cystic carcinoma. In the last 20 years, only 40 cases of adenoid cystic carcinoma arising in variable locations of the larynx have been reported in the English language literature. We present a case of adenoid cystic carcinoma of the larynx arising in the inter-arytenoid and postcricoid region in a 54-year-old woman. To our knowledge, this is the first case of adenoid cystic carcinoma arising in this particular region of the larynx.
