To-date the genomic landscape of cutaneous pericytic tumours (PTs), which represent a morphological continuum, have not been comprehensively explored. In order to identify the driver events of PTs from across their histological spectrum, and potentially aid the current classification system, we sequenced DNA (whole-exome) and RNA (pulldown transcriptome) from tumour-normal pairs classified by two different dermatopathologists of angioleiomyoma (n=37), glomus tumour (n=30) and myopericytoma (n=11); with all sequencing data deposited in the European Genome and Phenome Archive.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
