Core Tip	Anorectal mucosal melanoma (AMM) is rare, highly aggressive, and often presents with subtle or amelanotic lesions that are easily missed. We report a case of early local recurrence detected only through systematic colonoscopic withdrawal with rectal retroflexion and careful assessment of microvascular patterns. Despite appearing benign under narrow-band imaging, white-light endoscopy revealed suspicious lesions leading to biopsy-confirmed recurrence. This case highlights the critical role of meticulous, high-quality endoscopic surveillance in identifying early occult recurrence and underscores the need for individualized, standardized monitoring strategies in high-risk AMM patients.
