Objective This paper discusses the clinical characteristics and diagnostic and treatment process of tumours at metachronous colostomies to provide clinical experience for metachronous colorectal cancer at special sites.Method A clinical case of a patient presenting with tumour at the stoma 10 years after combined transabdominal perineal resection for low rectal cancer was retrospectively described,and relevant literature review was performed.Result Combining the patient's medical history,symptoms,signs and auxiliary examinations,it was considered that the tumours at the patient's stoma were due to improper stoma care and stimulation by repeated contamination with intestinal secretions and faeces.The patient's autoimmune system disease was also identified as a potential cause.Following the radical resection of the stoma tumours and surrounding skin,no signs of disease progression have been observed from post-operation to August 9,2023.Conclusion The diagnosis and treatment of metachronous colorectal cancer at special sites tends to be more individualised,and no standardised treatment plan has been formed yet.Regular monitoring and follow-up are effective ways for early detection and diagnosis and treatment,which is a reliable method to reduce the risk of systemic metastasis and improve the chance of R0 resection.
