Malignant transformation of tailgut cyst to squamous cell carcinoma, a rare case with poor outcome

Abstract

Abstract Tailgut cyst, a type of retro‐rectal cyst, is a rare condition requiring evaluation for malignant transformation. We report a case of squamous cell carcinoma arising in the retro‐rectal cyst, in a 51‐year‐old female who underwent incomplete resection of the cyst and chemo‐radiotherapy, subsequently became locally recurred and metastatic.
