title: Brain metastasis from basaloid carcinoma of the anal canal 8 years after abdominoperineal resection.
abstract: Basaloid carcinoma of the anal canal is a rare tumour originating from a persistent remnant of the cloacal membrane of the embryo. Wide abdominoperineal resection is the treatment of choice with a 5-year survival rate of 50%. A case of brain metastasis 8 years after abdominoperineal resection is reported. Postoperative radiotherapy may eradicate subclinical disease and prolong survival.
