Primary tumors of the small bowel are a rare condition, accounting for 2 to 3% of gastrointestinal tumors. Malignant melanoma is the most common metastatic tumor found in the gastrointestinal tract [1]. It can be localized in different sites, from the oral cavity to the anus. It can also be present as a primary lesion.

According to estimates from the International Agency for Research on Cancer, by the year 2030 there will be 22 million new cancer cases and 13 million deaths per year. The main reason for death from cancer is not the initial tumor but it’s metastasis to distant parts of the body, yet this process has remained poorly understood for quite some time.

Necroptosis is a form of programed necrosis mediated by receptor-interacting serine/threonine-protein kinase 1 (RIP1) and RIP3 and the subsequent phosphorylation of mixed lineage kinase domain-like protein (MLKL) [1-4]. Necroptosis has been implicated in multiple human diseases such as myocardial infarction, atherosclerosis, and abdominal aortic aneurysms (AAAs). Levels of RIP3 are elevated in the human tissues affected by these diseases.

The hyperfiltration theory of Brenner et al. in 1982 [1], is widely recognized and studied closely as a final common pathway of kidney function deterioration from some point to the irreversible end-stage by any first kidney insult. In the paper, the deterioration of kidney function is induced because of the glomerular hemodynamics,

It is long known that melanoma has the ability to metastasize widely. Unusual sites of metastases are seen including intracardiac. The literature reports cases of cardiac metastases however, most reports pre-date the more recent era of immunotherapy and targeted agent use and do not describe systemic treatment responses.
