Abstract
We report a case of adenosquamous carcinoma arising in the left side of the tongue. An 80-year-old man was referred to our hospital due to a painless tumor with ulcer in the left side of the tongue. Clinical examination showed an elastic hard mass measuring 30 × 30 mm in size. MRI revealed a well-defined mass in the left side of the tongue, of low intensity on T1-weighted images and moderate intensity on T2-weighted images. An incisional biopsy was carried out and revealed cancer, although the detailed histological diagnosis was unclear. MRI, CT, echo and FDG-PET did not show metastasis in cervical lymph nodes or other organs. Hemiglossectomy, supra-omohyoid neck dissection with reconstruction using a radial forearm flap was carried out. Histopathological examination of the surgical specimen showed adenosquamous carcinoma with two metastatic cervical lymph nodes. There has been no sign of recurrence or metastasis for 1 year, 4 months postoperatively.
