Successfully Resected Cardiac Metastatic Melanoma in a Lifesaving Cardiac Surgery: A Case Report

Metastatic tumors are the most frequent tumors of the heart with the melanoma metastasis being the most frequent. In cases of a cardiac tamponade or a low cardiac output syndrome due to the position of the tumor it could lead to an acute life-threatening condition for the patient.

We present a case of a successfully treated metastatic cardiac melanoma in a lifesaving cardiac surgery. A 42-year-old woman was admitted to the emergency department of the Clinical Center of Serbia in a critical state with signs of tricuspid orifice obstruction with a tumor mass. Her previous medical history showed that she had an adequate surgical excision of the melanoma in the right lumbar region at the age of 39. An emergency cardiac surgery was performed with the resection of the tumor and the atrial wall. The postoperative course was uneventful and a HP exam once again confirmed the same type of melanoma as previously diagnosed. The patient was alive and well on follow-up exams for 4 months when she was diagnosed with metastatic tumor masses in the pelvis with ascites and melanosis of the entire skin followed by lethal outcome 5 months after the cardiac surgery.

Surgical resection of metastatic cardiac melanoma can be safe and effective in an emergency scenario, especially in the case of solitary metastasis. It can be performed with excellent results and very few postoperative complications. However, due to the nature of the principal disease, the long-term survival rate remains low, giving the surgery a place in palliative treatment.
