Anorectal melanoma was first described by Moore in 1857. Is an uncommon and aggresive tumor, with inauspicious prognosis. Five-year survival rates are less than 20%. The main important feature of this tumor is that it usually manifests as a rectal tumor or rectal bleeding; therefore, a diferential diagnosis with benign anal conditions is of utmost importance. Prognosis is conditioned by tumor stage at diagnosis. We present a 70-year-old woman with rectal bleeding with an initial diagnosis of hemorrhoidal trombosis. With the diagnosis of rectal melanoma without distant metastasis, an abdominoperineal resection (Miles operation) was performed. After 9-years follow-up, she is disease free.
