Adenocarcinoma in a tailgut cyst: A rare case report

ABSTRACT

Tailgut cysts (TGCs) are rare congenital lesions derived from the remnants of primitive hindgut and are usually lined by squamous, transitional, or glandular epithelium. Malignant transformation in TGC may occur which is still rarer. Most common malignancies that arise from these cysts are adenocarcinomas. Preoperative diagnosis is difficult as high degree of suspicion is required for the diagnosis. We report here a case of adenocarcinoma arising in a tale gut cyst diagnosed preoperatively and till date very few cases have been reported in literature
