(N-NITROSO) PROPAFENONE INDUCED ADVANCED NODULAR MELANOMA-FIRST REPORTED CASE IN THE WORLD LITERATURE: THE INEXTRICABLE LINKS BETWEEN THE PHOTOCARCINOGENESIS, DRUG RELATED NITROSOGENESIS AND PHARMACO-ONCOGENESIS.

Onco-pharmacogenesis or pharmaco-oncogenesis of skin cancer is a concept , which could also be considered as an "end product" of drug-mediated Nitrosogenesis or of the permissive regime for carcinogens to be (un)controlled released in drugs. Their controlled distribution remains until 2025 as a forced and non-alternative and there is no indication of any possibility to introduce a full elimination regime against the already mentioned carcinogenic availability. There are three main worrying facts that determine the need for these elimination regimes: 1) the clinicopathological correlations concerning the intake of a heterogeneous class of drugs and the subsequent development of relatively homogeneous tumours/ such as melanoma, 2) the recently proven mutagenic/ carcinogenic action of certain nitrosamines, but this time directly on human DNA, and 3) the fact that some of the nitrosamines are potent photocarcinogens that exert their genotoxic effects only after irradiation with UVA/ also recently proven/. In addition to the rhetoric mentioned above, there is also an overlap in mutational patterns between the genes previously generally accepted to affect melanomas - p53 / RAS oncogenes , with those identified as target genes, but being affected "mutationally", by certain nitrosamines. The processes of photocarcinogenesis, nitrosogenesis and oncopharmacogenesis of skin cancer are inextricably linked and should not be considered and analysed unilaterally or in a semi-invasive manner. Cataloguing the type of nitrosamines and their precise concentration on drug leaflets and prescription/official websites with permanent access to clinicians and end-users remains the only safe and effective weapon in the fight against (un)controlled contamination. The pharmaceutical industry and regulators remain the creators, the 'parents' of onco-pharmacogenesis, nitrosogenesis, and therefore the processes involved in the generation and progression of skin cancer. The impossibility of establishing elimination regimes for certain mutagens and/or carcinogens already proven to be present in medicines remains a mystery. In practice, end consumers find themselves in a state of enforced tolerance of certain genotoxic substances that are not even declared as available. Clinicians in the face of dermatologists/ dermatological surgeons remain the analysers and identifiers of these globalization processes. Once again, we present a patient who took the antiarrhythmic (nitroso-) drug propafenone and developed a relatively short-term nodular melanoma with a subsequent fatal outcome. We comment on the role of drug-mediated nitrosogenesis and its relationship to photocarcinogenesis and onco-pharmacogenesis.
