[Primary digestive melanomas: is there any consensus?].

In clinical practice and the literature, malignant melanoma usually appears in typical sites where melanocytes can be found: skin, eyes meninges and anal region. Malignant melanomas of the esophagus-gastrointestinal (EGI) tract are usually metastatic. Primary and diffuse EGI tract melanoma is rare and only a few descriptions of this presentation have been found in the literature. The prognosis of EGI tract melanoma is frightening because of late diagnosis and high malignancy potential. Treatment is based essentially on surgery. The objective of the present study is to specify the clinical and therapeutic aspects of primary digestive melanoma.
