title: [Late malignant melanoma metastases within the abdominal cavity imitating clinically and pathologically a gastrointestinal stromal tumor].
abstract: Melanoma is a malignant skin neoplasm that often metastasizes within the abdominal cavity. Melanoma metastases can develop even many years after the primary treatment. Clinical course, microscopic histology, and immunohistochemical profile of melanoma may imitate a gastrointestinal stromal tumor (GIST). We report a case of 55-year old man with a history of melanoma treatment 23 years earlier who presented with recurrent duodenal bleeding from a neoplastic tumor that was primarily diagnosed as GIST The histology of the tumor was reviewed and confirmed the diagnosis of metastatic melanoma.
