A rare case of adenocarcinoma arising within a duplication cyst of the rectum: curative excision with 9-year follow-up

Abstract

This case report is novel in that it describes the successful excision of an adenocarcinoma arising within a rectal duplication cyst without evidence of disease recurrence at 9-years of follow-up.

Anterior Anorectocolonic Tubular Duplication Presenting as Rectovestibular Fistula in an Infant

“…The severity of these symptoms increases with the age at presentation. Malignant degeneration of duplications has also been reported [3,9,10]. The symptoms reported for anterior anorectal duplications are similar to those for posterior anorectal duplications, including recurrent gastroenteritis and failure to thrive, isolated rectal bleeding, chronic constipation with soiling, and rectal prolapse [7].…”

“…If an anorectal duplication is not treated, secretions accumulate in the lumen of the duplication, leading to infection with age [1]. Malignant changes in anorectal duplications have also been reported in adult patients, although not in pediatric populations [1,10]. When there was no evidence of fistula formation between the duplication cyst and vagina, cyst unroofing and residual mucosa ablation was applied [7].…”

Adénocarcinome rectal six ans après chirurgie d’une duplication rectale kystique

“…Le plus souvent, il s'agit d'un tableau d'hémorragie digestive basse, d'obstruction intestinale, de fistule périanale plus ou moins associée à une masse pelvienne, parfois de douleurs pelviennes (le cas de notre patient) et exceptionnellement de transformation d'emblée [5][6][7].…”

“…La résection chirurgicale est toujours de mise, permettant de confirmer par l'étude de la pièce opératoire la nature histologique de la duplication kystique et de rechercher des signes de transformation maligne [7,8].…”

Rectosigmoid tubular duplication presenting as perineal sepsis in a neonate

“…This presents as rectal bleeding, perineal fistula, or pruritus ani [13]. Although it is extremely rare, rectal duplications are reported to have the potential for malignant change, most of which occur in patients older than 30 years and all of which were reported cases of adenocarcinoma [14][15][16].…”
