Retro-rectal cystic hamartoma or tailgut cyst is a benign tumour of congenital origin with recurring potential and an enclosed malignancy.
In the case of a 59-year-old patient with a potentially recurrent tumour of 14cm that exceeded the limits of the retro rectal region and progressed downwards to the right anal region and retro coccygeal, its excision is supposed to be complete and confirmed by CT scan postoperatively, which was performed via three ways. However, relapse occurred as adenocarcinoma seven years later, probably from some tumour cells, and this recurrence confirmed the insufficiency of excising the tumour alone.
In our study, Pub Med, Google Scholar, and Scopus databases were consulted. The research was: Tailgut Cyst, Retrorectal tumours, and malignancy; we found 399 cases, of which some were solitary and others published through series. The tumour would, therefore, not be as rare as we previously assumed.
We present an analysis to unveil recurrences and their malignant transformations in adults. We also propose preventive measures and possible treatments during and after surgery.
