Adenosquamous Carcinoma
In total 9 patients were diagnosed with the adenosquamous variant of SCC, and for all the patients, surgery was the primary treatment method. In one patient neck dissection was not performed due to previous neck irradiation history for nasopharyngeal carcinoma. The information about the treatment modalities of the primary disease, recurrence, and treatment of recurrence is given in Table 3 .
During the follow-up, one patient was lost due to cerebrovascular accident and its related complications and one due to systemic recurrence of the primary disease. The remaining 7 patients were disease-free at the last follow-up.
The median follow-up duration is 61 months (17-144). 5-years disease-specific survival is %83,3% and the overall survival is 72,9 %.
