Abstract
When talking about "Melanoma" it is easy to think that it is a malignant tumor produced by the alteration of melanocytes, but we leave aside that there can also be melanomas in the mucous membrane, it is certainly an atypical presentation but not impossible. Now, a melanoma in the anal mucosa is still an atypical and unusual presentation, adding that its symptoms are variable, and can be confused with any other pathology, which makes its diagnosis difficult and impoverishes its prognosis as there is no early treatment.
We present the case of a woman in her sixth decade of life, with non-specific symptoms in the anal region. Being a rare case, it is right to emphasize its clinicopathological importance.
