Combined small cell carcinoma (SMCC) of the larynx consists of SMCC admixed with a component of squamous cell carcinoma or adenocarcinoma. These tumors are very rare and, to date, only a few cases have been fully described. This points out the lack of information available about the correct management of these patients. Here, we describe two additional cases of combined SMCC of the larynx that illustrate the difficulties that we can encounter to diagnose correctly these patients and, by consequence, to treat them adequately.
