Article Synopsis
- Malignant sweat gland tumors, particularly eccrine porocarcinoma (EP), are rare, with about 18% of benign eccrine poroma (EPO) cases progressing to EP, highlighting a need for more understanding of EP biology and mutations involved in this transformation.
- Transcriptome profiling of 23 EP and normal skin samples showed significant gene expression diversity and downregulation in EP, including specific genes that indicated a stepwise transition from normal skin to EPO to EP.
- The study suggests that EP has a complex molecular nature linked to tumor development, with potential involvement of the p53 and EGFR pathways, and calls for further research with larger sample sizes to validate these findings.
Background: The coronavirus disease 2019 (COVID-19) is associated with a wide clinical spectrum of skin manifestations, including urticarial, vesicular, vasculitic and chilblain-like lesions. Recently, delayed skin reactions have been reported in 1% individuals following mRNA vaccination against SARS-CoV-2. The exact pathophysiology and the risk factors still remain unclear.

To investigate the mutational landscape of EP, we performed whole-exome sequencing (WES) on 14 formalin-fixed paraffin-embedded samples of matched primary EP and healthy surrounding tissue. Mutational profiling revealed a high overall median mutation rate.

The challenges surrounding an AB+CD approach are described with focus on understanding the formation of ring-opened side products when using amide coupling reagents. To avoid undesired side product formation, a strategy of iterative ring-openings of cyclic sulfamidates on solid-phase is explored.
