A65 year-old women presented with two months history of abdominal pain and
obstructive jaundice. Fifteen years earlier, she had undergone malignant
melanoma excision of the face. A computed tomographic scan showed Intra biliary
tree dilatation related to a nodular lesion (6 cm of diameter) at the liver
anterior segment. An ultrasonography-guided biopsy was carried out and the
histological report confirmed the diagnosis of malignant melanoma metastasis.
An endoscopic retrograde cholangiopancreatography (ERCP) was performed for
biliary stenting, during duodenoscopy; we found an umbilicate vegetating
ulcerating lesion on the posterior wall of gastric body.
Thehistological study of the vegetating lesion revealed gastric malignant melanoma
metastasis. Patient transferred to oncology department for chemotherapy.
Melanoma is an unusual predilection to metastasize to the gastrointestinal
tract. Only 1-5% cases of metastatic melanoma are diagnosed during life because
they are generally clinically asymptomatic in the early stages. Diagnosis often
takes place when an emergency complication occurs, such as intestinal
perforation, obstruction, and acute gastrointestinal bleeding, or with non-specific
symptoms like anaemia, weight loss, abdominal pain.
