The incidence of melanoma is increasing worldwide. It is known that melanoma frequently progresses to metastatic disease. The aim of this report is to emphasise the metastatic potential of cutaneous melanoma to various body areas, as well as the ability to produce unexpected presentation of the disease. A 48-year female had a myomatous uterus and underwent hysterectomy. At the pathological examination, multiple leiomyomas were diagnosed and in one of them, the metastatic melanoma was found, the later confirmed with immunohistochemical analysis. The medical history revealed that the patient was previously operated two years back due to skin superficial spreading melanoma. The metastasis to uterine leiomyoma was the first site of distant spread. Melanoma is a type of tumour with aggressive and unpredictable behaviour, so metastases to unexpected localisations could occur. A careful examination of patient's body is mandatory, including the remote areas and even benign tumours.

Recent advances in oncology research have highlighted the promising synergy between low-dose radiation therapy (LDRT) and immunotherapies, with growing evidence highlighting the unique benefits of the combination. LDRT has emerged as a potent tool for stimulating the immune system, triggering systemic antitumor effects by remodeling the tumor microenvironment. Notably, LDRT demonstrates remarkable efficacy even in challenging metastatic sites such as the liver (uveal) and brain (cutaneous), particularly in advanced melanoma stages.

RNA methylation is a pivotal epigenetic modification that adjusts various aspects of RNA biology, including nuclear transport, stability, and the efficiency of translation for specific RNA candidates. The methylation of RNA involves the addition of methyl groups to specific bases and can occur at different sites, resulting in distinct forms, such as N6-methyladenosine (mA), N1-methyladenosine (mA), 5-methylcytosine (mC), and 7-methylguanosine (mG). Maintaining an optimal equilibrium of RNA methylation is crucial for fundamental cellular activities such as cell survival, proliferation, and migration.

The global incidence of metastatic melanoma with BRAF mutations, characterized by aggressive behavior and poor prognosis, is rising. Recent treatment advances, including immune checkpoint inhibitors (ICI) and targeted therapies (TT) such as BRAF and MEK inhibitors, have significantly enhanced patient outcomes. Although guidelines recommend sequencing strategies, real-world implementation can be influenced by clinical scenarios.
