Concomitant squamous cell carcinoma of the cervix and adenocarcinoma of the rectum.

Multiple primary cancers are rare and its first description was made by Billroth in 1879. Recently, this condition has been detected with increasing frequency which may be explained by improved clinical awareness, contribution of other factors including carcinogenic effect of radiation, new environmental carcinogenic factors and also increased life expectancy of cancer patients to enable them to live long enough to develop a second primary cancer. Most secondary tumours develop after a period of time, which may last for years. However, two or more primary malignant tumours may be found concomitantly in a patient. We report a case with concomitant squamous cell carcinoma of the cervix and adenocarcinoma of the rectum identified incidentally in an operation performed for carcinoma of the uterine cervix.
