Sialadenoma Papilliferum (SP) is a benign salivary gland tumor characterized by an exophytic and endophytic epithelial proliferation of mucosa of salivary gland origin. Typically, these tumors appear on the palate, with most cases involving the hard palate. Several cases have been described, on the soft palate, buccal mucosa, tongue and bronchi. We present the first documented case of laryngeal SP, associated with a previous history of recurrent laryngeal papilloma. Our case report is unique in two ways. Firstly, it is the first case reported in the larynx. Very few cases along the lower respiratory tract have been reported, but none on the vocal folds. Secondly, it is the first case associated with a previous history of squamous papilloma. High level of alertness is required in order to identify this rare diagnosis.
