adénocarcinome anal sur fistule anale: à propos de 3 cas en Côte d’ivoire

Abstract

From three observations about anal carcinoma that occurred on anal fistula, we performed a study which purpose was to discuss about their etiopathogenic, diagnostic and therapeutic aspects. Authors report 3 cases of anal carcinoma that occurred on chronic and recurrent anal fistula. There were a 40 years old woman and two men of 47 and 51 years. They underwent fistulotomy for chronic anal fistula respectively 3, 5 and 19 years ago without any histologic examination of swab. Clinical examination revealed that anal fistula was tumor like in one case and ordinary in two cases. Diagnosis was suspected on colloidal nature in two cases and on muco hematic aspect of the contents of the fistula in one case. Diagnosis was confirmed by histologic examination of swab and / or biopsy specimens that revealed colloid adenocarcinoma that leads us to evocate that the lesion originates from anal gland. None patient underwent radiation therapy; one of them refused any treatment, the other two underwent abdominoperineal resection. From now any anal chronic suppuration should systematically be examined histologically.
