Core Tip
Core tip: Gastrointestinal stromal tumors (GIST) are an uncommon group of tumors of mesenchymal origin. GIST of the anal canal is extremely rare. Here, the authors describe the case of a 73-year-old man with a mass in the anal canal, and no other symptoms. The patient was treated by local excision. An abdomino-perineal resection was discussed, but refused. After 5 years follow-up with clinical evaluation and anal ultrasound, the patient is well, with maintained continence and no evidence of local recurrence.
