A Case of Adenosquamous Carcinoma of the Sigmoid Colon with Synchronous Multiple Liver Metastases

Abstract

We report a case of adenosquamous carcinoma of the sigmoid colon with synchronous multiple liver metastases. A 51-year-old man was admitted to our hospital complaining of constipation and melena. A biopsy specimen histologically revealed a well differentiated adenocarcinoma. He was diagnosed as having an advanced sigmoid colon cancer with multiple liver metastases based on imaging findings. Sigmoidectomy was performed for the relief of symptoms like bleeding and stenosis. Macroscopically, the type 2 tumor had across section 3.5×3.0cm and was located in the sigmoid colon. Histological findings showed an adenosquamous carcinoma invading the subserosa. He postoperatively received chemotherapy (FOLFOX). However, the patient died 35 days after surgery because of respiratory failure and liver failure.
