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.
