Malignant melanoma is a tumor that arises from melanocytes of the skin or mucous less frequently (oral, anal or genital). It has also been described in vagina, leptomeninges and eyeball.^1,3,4 The age of onset is between 40 and 60, but it may occur at any age. Its development is influenced by genetic and environmental factors.^2.3 In recent years there has been an exponential growth in cases of this disease. Is the leading cause of death from skin cancer and has a biological behavior that determines the outcome. It has two phases of growth, intraepidermal and intradermal, which is capable of producing metastases (which occur during the first three years of the initial injury) as a result of the invasion of the basement membrane, migration into the bloodstream or lymphatic circulation, which represents more than 50% of the route of dissemination.^1,3,4 The diagnostic method of choice is the removal and histological examination of a suspicious lesion. A case of a male patient aged 45, who consulted for strong epigastrical pain of insidious onset radiating to right upper quadrant. Concomitantly fever and nausea. As regards history right eyeball enucleation due to a tumor whose histology was compatible with melanoma. Abdominal ultrasound reported images suggestive of liver metastases, which biopsy was reported as: Metastatic melanoma. Upper gastrointestinal endoscopy: low gastric body lesion is seen with irregular edges, color blackish, slightly elevated, whose biopsy was negative for malignancy. This case is reported due to the poor prognosis of this disease and the uncommonless of this presentation.
