title: Adenosquamous carcinoma of the colon: a rare tumor.
abstract: Adenosquamous carcinoma of the colon is rare. A paraneoplastic syndrome presenting as hypercalcemia may occasionally occur in association with these tumors. Survival for more advanced stages of disease is lower than for patients with adenocarcinoma at a corresponding stage. We report a patient who presented with a primary adenosquamous carcinoma of the rectosigmoid junction and we review the literature regarding the clinical presentation, management, and prognosis of this tumor.
