摘要

本文報告一罕見腺樣鱗狀細胞癌發生於47歲男性病患左頰黏膜之病例，腺樣鱗狀細胞癌極爲少見且預後不佳，同時出現腺體癌及鱗狀細胞癌之病理特徵。自1968年以來只有59例發生於頭頸部之病例報告於英文期刊上，雖然過去的報告顯示此癌症之預後極差，但本病例經兩次徹底手術後、經五年追蹤並無發生局部復發及遠端轉移的情形，因此特就此癌症之臨床特徵及病理診斷依據作一介紹及討論。

This paper reports a rare case of adenosquamous carcinoma that involved the left buccal mucosa in a 47-year-old man, with rapidly tumor recurrence in two month after an initial surgery. Adenosquamous carcinoma is a very rare malignant tumor with poor prognosis that characterized histopathologically by the simultaneous presence of distinct areas of adenocarcinoma and squamous cell carcinoma. Only 59 cases of adenosquamous carcinoma within the head and neck region have been documented in the English literature since 1968. Although most of the previous report showed very poor prognosis with these tumor, fortunately, after two major radical operations and without postoperative radiotherapy, our patient still maintains a good condition with no further evidence of tumor recurrence and metastasis for more than five years after surgery.
