dc.description.abstractOne of the unusual characteristics of cutaneous melanoma is its ability to metastasize in the small intestine. It is often diagnosed during autopsies of cutaneous melanoma patients. Metastatic deposits have been found in 50% to 60% of these autopsies, but less than 2% to 4% of patients diagnosed with melanoma have gastrointestinal metastasis during the course of the disease. Between 4% and 9% of gastrointestinal melanoma cases have unknown primary tumors. Rapid identification and resection of melanoma in the digestive tract could improve the patient survival rate and prevent complications such as intestinal obstructions from occurring. We present a rare clinical case of gastrointestinal melanoma of unknown primary origin. The patient had a clinical picture of nausea, hyporexia, epigastralgia, fatigue, paresthesias in the right dorsal region and had lost nine kilograms in three weeks. An abdominal CT scan showed three predominantly isodense liver lesions in the parenchyma, with some areas of lower density located in segments 2,5,7 and 8 of the liver. These were biopsied. Upper digestive tract endoscopy took biopsy samples of two hyperpigmented lesions in the second portion of the duodenum. Histopathological examination showed malignant melanoma. All typical locations of primary melanoma were excluded during the diagnostic procedure. © 2019 Asociaciones Colombianas de Gastroenterología, Endoscopia digestiva, Coloproctología y Hepatología.eng
