Abstract:
Melanoma is a very aggressive skin cancer that could metastasize to any organ in the body. The treatment of melanomas includes surgical resection, chemotherapy, and immunotherapy. After resections, melanomas could recur at the previous site or present as a distant metastatic lesion. The symptoms of melanoma are vague and primarily occur because of the local disruption of the tissue architecture. Presented here is a case of gastric melanoma that presented with abdominal discomfort and melena in a patient with a history of penile melanoma that was completely resected 3 years earlier. This case illustrates the importance of having metastatic lesions to the intestinal tract as a differential for a patient with gastrointestinal hemorrhage.
