Introduction: The aim of this manuscript is to present the clinical manifestations of the disease and to discuss the diagnosis and treatment methods.Malignant anal melanoma is a rare disorder, reported in approximately 600 cases in literature, and has never been referred as coexisting with colon adenocarcinoma. A review of investigation measures and conduct is also presented.

Case Presentation: The authors present the case of a 57-year-old male patient with a positive fecal-occult blood test, and a previous diagnosis of spoliative anemia. The patient was diagnosed with synchronous anal melanoma and colon adenocarcinoma.

Conclusion: Synchronous anal melanoma and colon adenocarcinoma are an extremely rare disease and it has a very poor prognosis. For this reason is fundamental the early diagnosis and treatment. In surgical treatments all the resections should be sent to anatomopathological examination to try an early diagnosis and by these measures try to improve patients prognosis. Being a rare disorder there is a lack of studies regarding how to act in this situation.
