腺癌是結腸癌最常見的惡性腫瘤。原發性結腸腺狀鱗狀上皮癌是一種罕見的情況。最常發生的位置是結腸的近端部分。腫瘤好發於年輕人並且具有高度侵略性，預後通常是不良的。我們提出一個女性病例，被診斷出盲腸腺狀鱗狀上皮癌同時合併轉位異常及腸套疊。因為發生機率很低，而且發生原因及疾病預後並不明確，在此我們提出討論。

The most common malignant tumor of the colon is adenocarcinoma. Primary adenosquamous carcinoma of the colon is a rare entity. Its prevalent site of origin is the proximal portion of the colon, except the anorectum. The tumor typically presents in young patients and follows a highly aggressive course with a characteristically poor prognosis. We present a female patient who complained of left lower quadrant pain and a palpable mass for one week. She was found to have ileocecal intussusception and a cecal tumor was strongly suspected. Malrotation of the colon was noted during laparotomy and the patient received right hemicolectomy. Histological examination revealed that the tumor was an adenosquamous carcinoma. Because of its very low incidence, the histogenesis and prognosis of this disease remain unclear. Consequently, further clinical and histological study of this disease entity is required.
