Abstract

Background:

Adenosquamous carcinoma is a rare variant of semicircular canal that can affect various regions, including the head and neck. Adenosquamous carcinoma is characterised pathologically by the simultaneous presence of distinct areas of semicircular canal and adenocarcinoma, and usually takes an aggressive course with local recurrences, early lymph node metastases and distant disseminations.

Case:

We report a rare case of neck adenosquamous carcinoma of unknown primary origin, which was well-controlled by thorough resection without any other additional therapy.

Conclusion:

We discuss the diagnosis and treatment of adenosquamous carcinoma along with a review of pertinent literature. We also consider the potential differential diagnosis of branchiogenic carcinoma.
