CYLD and adnexal spiradenoma/cylindroma of a sweat gland: Using fresh pulmonary and skin tumour tissue, we characterized the CYLD locus using polymerase chain reaction coupled with next‐generation sequencing, demonstrating loss of heterozygosity, a feature reported in 75% of cutaneous cylindroma (Fig. 3a).2 Transcriptomic profiling was performed of lung tumours.
