**Abstract**

Malignant melanoma is an aggressive disease. The anorectal region is the most common site of primary gastrointestinal malignant melanoma. Due to its low incidence, the diagnosis is often delayed. The most characteristic clinical feature of this tumor is its brown-black appearance due to the melanin pigment. However, the pigmentation may be absent in up to 20% cases. Timely diagnosis and treatment are crucial for achieving good long-term outcomes. Surgical excision remains the treatment of choice for localized disease. However, the extent of surgery has been a matter of debate. Anorectal melanoma is a highly malignant disease, and more than 50% cases have metastasis at the time of diagnosis. Targeted therapies especially immune check point inhibitors have brought about a paradigm shift in the management of cutaneous melanoma. They are being increasingly used for mucosal melanomas, and their role in anorectal melanoma is being investigated in various clinical trials.
