증례 : 대장 샘암종 환자에서 이시성으로 발생한 간의 샘편평세포암종 1예 = Case Reports : An adenosquamous carcinoma of the Liver that developed metachronously in a patient with a colon adenocarcinoma

국문 초록 (Abstract)

간의 원발성 샘편평세포암종은 드물게 발생하며, 간의 다른 원발성 종양보다 불량한 예후를 가지고 있다. 저자들은 상행결장암으로 수술 후 항암화학요법 중 우연히 발견된 간의 원발성 샘편평세포암종을 경험하였기에 보고한다.

다국어 초록 (Multilingual Abstract)

A primary adenosquamous carcinoma of the liver is a rare subtype of a cholangiocarcinoma. Adenosquamous carcinoma is known to have an aggressive biologic behavior and is associated with a poor prognosis. Recently, we experienced a case of a primary adenosquamous carcinoma of the liver. A 69-year-old man was subjected to a right hemicolectomy five months ago due to an ascending colon cancer. At a periodic check-up, abdominal ultrasonography and magnetic resonance imaging showed a ~1.1 cm-sized hepatic mass which was highly suspicious of being a hepatic metastasis from the ascending colon cancer. A hepatic segmentectomy was performed. The tumor was microscopically composed of an adenocarcinoma and a squamous cell carcinoma, and it was different from the previous colon cancer as determined by immunohistochemistry. Three months after the hepatic segmentectomy, multiple hepatic metastasis was found and the patient has been treated as an outpatient with capecitabine. (Korean J Med 72:74-78, 2007)
