Autopsies represent medical procedures through which the causes of patients' deaths are determined or, through tissue sampling and microscopic examination of slides in usual stains or special tests, one can offer the basis for understanding the physiopathological mechanisms that contribute to the patients' death Histological findings of tissue samples from patients who have died of COVID-19 have been mainly orientated to lung, heart, liver, kidney damage with a small percent of them following other organs, but none has, to our knowledge, studied skeletal muscle.

Cutaneous melanoma remains a major health issue and still an important challenge for research. Thus, omics complex evaluation can provide a more specific molecular classification for this heterogeneous disease. Complex omics analysis based on genomic and proteomic microarrays can identify disease markers that prognosticate disease evolution or can monitor therapies efficacy. Among the technologies that gained momentum in the last years, array-based comparative genomic hybridization offered the possibility to analyze chromosomal numerical aberrations within cutaneous melanomas providing important support for molecular classification of melanoma tumors. This technology can identify new chromosomal alterations and discover new deregulated melanoma genes that can be further used as therapy targets. Integrating genetic profiling with clinical and pathological parameters would lead to seminal improvements in diagnosis, prognosis, and therapy. [ABSTRACT FROM AUTHOR]
