Metastatic melanoma presenting as cardiac mass and hemobilia.
We present a rare case of malignant melanoma of unknown primary origin presenting as cardiac and cholecystic masses. In this 72-year-old man, a cardiac lesion caused right ventricular outlet obstruction, and gallbladder lesions led to hemobilia. Right atrial and gallbladder metastases were resected. After 2 years of disease-free survival, the patient had recurrent skin lesions, which were treated with local resection and dacarbazine. The patient has survived for more than 5 years after initial diagnosis, with continued complete clinical remission. This case illustrates the importance of aggressive surgical resection and chemotherapy in the treatment of metastatic malignant melanoma.
