Adenosquamous Carcinoma in Distal Transverse Colon in a 72-Year-Old Female Patient

Abstract

Adenocarcinoma accounts for most of the malignant tumors which originate from the colon, whereas the adenosquamous carcinoma is rather rare, totaling to about 0.06% of all colon cancers. Herein, we present a case of adenosquamous carcinoma of the transverse colon with hepatic metastasis. The patient is a 72-year-old woman who is presented with a chief of lower abdominal pains. Her colonoscopy has indicated an ulcerofungating mass about 4 cm × 3 cm in size in the distal transverse colon, and the biopsy confirmed her diagnosis of adenosquamous carcinoma. An abdominopelvic computed tomography shows an circumferential enhancing mass on her distal transverse colon with three hepatic metastatic nodules. Transverse colectomy and hepatectomy are later being performed.
