Core Tip

Core Tip: Tailgut cysts (TGCs) are rare congenital cysts of the retrorectal space. We report a case of TGC with adenocarcinogenesis and review the literature on caudal cyst adenocarcinogenesis. Magnetic resonance imaging is the most valuable tool for diagnosis and differential diagnosis, and preoperative biopsy is not worth advocating. Early MDT plays an important role in the accurate diagnosis and selection of the most appropriate personalized treatment. Complete resection of TGCs is the key to avoiding postoperative recurrence. We recommend MDT with complete surgical resection as the core and discuss the advantages and disadvantages of various diagnostic and treatment strategies.
