Abstract: Adenosquamous carcinoma of the colon consisting of both glandular and squamous histopathologic features is a rare
colorectal neoplasm. Metastasis commonly occurs in right and transverse colon. A 71-year-old Caucasian man presented with a
four-month history of intermittent rectal bleeding. Pathologic analysis of biopsy specimen revealed an adenosquamous carcinoma of
sigmoid colon. Sigmoid resection with a proximal and distal resection was performed. Early detection and radical operation with other
available therapeutic modalities may improve clinical outcome. (IJCEM1304007).
