Primary anorectal melanoma is a rare malignancy with an extremely aggressive biological behaviour. The main clinical presentations are local symptoms such as rectal bleeding, anal mass or pain, or a change in bowel habits. The tumour is frequently mistaken for benign conditions as haemorrhoids or rectal polyps. Many treatments can be used: surgery, chemotherapy, radiotherapy, immunotherapy and even biotherapy. Despite this, the disease has a very poor prognosis and <10% of patients survive >5 years.
