Metastatic primary gastric melanoma: a rare clinical presentation and a review of literature

This is the authors' abstract. We don't add key points for this paper.

Primary gastric melanoma is a rare clinical finding. It presents with upper gastrointestinal symptoms like abdominal pain, weight loss and melaena. It is often difficult to differentiate a primary gastric melanoma from primary cutaneous melanoma with gastric metastasis. Upper gastrointestinal endoscopy and biopsy of the lesion for histopathology and immunohistochemistry help to reach a definite diagnosis. We report a case of primary gastric melanoma with metastases to the liver and bone. The patient was treated with palliative radiotherapy, palliative chemotherapy and a bone-stabilising agent.
