Discordant courses of COVID-19 in a cohabiting couple of lung transplant recipients.

COVID-19 is a novel infectious disease caused by SARS-CoV-2 that emerged in late 2019 and which is now a pandemic. Solid organ transplant recipients are perceived to be at increased risk of severe COVID-19 due to their chronic use of immunosuppressive drugs (ISDs) and to their associated conditions. Scarce data are available on the optimized management of ISDs in these patients and on its impact on presentation, clinical course, viral shedding, and outcome.

Genetic variant of SRF-rearranged myofibroma with a misleading nuclear expression of STAT6 and STAT6 involvement as 3' fusion partner.

Pediatric neoplasms with a myofibroblastic differentiation are frequent in children, in particular myofibroma. Recently, a novel deep soft tissue myofibroblastic neoplasm has been described with high cellularity, a smooth muscle phenotype and SRF-RELA fusion. We report the case of a 15-year-old boy who presented with a tumor of the deep soft tissue of the arm, with overlapping histological features with the recently described SRF-RELA group of myofibromas but differing by the presence of calcifications, a novel SRF-STAT6 fusion transcript and nuclear expression of STAT6.
