title: [Fistula-type pararectal mucinous carcinoma. A case report (author's transl)].
abstract: A case of the exceptionally rare fistula type of pararectal mucinous carcinoma is reported, the patient presenting with clinical signs of a chronic abscess in the ischiorectal hollow. The unusual gelatinous secretion suggested the need for a biopsy of the fistula cavity. Pathological examination confirmed the diagnosis, where as a barium enema and rectoscopy gave negative results, eliminating the possibility of a digestive tract origin for the tumour. Local recurrence occurred two and a half years after an abdominoperineal resection, and was treated by local excision. Aetiopathogenic hypotheses and current therapeutic procedures are discussed.
