The Food and Drug Administration (FDA) had approved fingolimod usage for multiple sclerosis in 2010. Melanoma after the usage of fingolimod immunomodulation was reported rarely in clinical trials, and only two case reports exist in the published literature, both occurring in Europe. Most of the incidences reported in clinical trials were in-situ, whereas both case reports were of malignant melanoma. Fingolimod has been found to inhibit metastatic melanoma growth in a mouse model that depends on vascular endothelial growth factor (VEGF)-induced angiogenesis for metastasis. However, there are numerous pathways of angiogenesis and tumour growth found in vivo by which melanoma can expand that do not mandate VEGF. We report a case of superficial spreading malignant melanoma occurring after fingolimod therapy in the USA.
