Adenocarcinoma arising in a rectal duplication cyst with distant metastasis A case report and a review of the recent literature.

INTRODUCTION

Rectal duplication cysts are rare cystic lesions, arising from the hindgut and classified as congenital/developmental tumors of the presacral space. Their clinical presentation is nonspecific, the diagnosis remains difficult and their management is aided by a multidisciplinary evaluation.

CASE REPORT: We report the case of a 55-year-old woman with a cystic mass located in the retrorectal space and identified incidentally on a CT scan. Following imaging studies, surgical resection by a posterior approach (Kraske procedure) was carried out and an adenocarcinoma arising in a duplication cyst of the rectum was present an uncommon case of a rectal duplication cyst with malignant transformation and distant metastasis, describe the clinical, radiologic and pathologic findings and discuss tidentified by microscopy.

CONCLUSION

We phe embryological basis of rectal duplication cysts and the surgical anatomy of the presacral space. Key Words: Rectal adenocarcinoma, rectal duplication cyst, Retrorectal space.
