title: Percutaneous aspiration biopsy in perineal recurrences after abdominoperineal extirpations.
abstract: The authors recommend the introduction of percutaneous aspiration biopsy--a new method used by them for demonstrating perineal recurrences after abdominoperineal extirpations. The method is fast and easy to perform, simple and can be used for screening. It may be an addition to the therapeutic and diagnostic arsenal.
