Published by BMJ.Oral focal mucinosis (OFM) is an extremely rare, benign oral soft tissue condition; less than 10 documented cases have been reported in the literature in patients under 18 years old. OFM has an unknown aetiology and predominantly presents in the fourth and fifth decades. The pathogenesis of OFM may be due to fibroblast overproduction of hyaluronic acid. Clinically, it remains almost impossible to diagnose definitively, due to its lack of pathognomonic features, therefore such lesions may have multiple differential diagnoses and histological analysis is essential to confirm OFM. We present an unusual presentation of OFM in a 14-year-old female patient. Following excision, focal myxoid degeneration of the connective tissue was apparent. This case highlights this rare condition for consideration in differential diagnosis of clinically similar lesions. © BMJ Publishing Group Limited 2020. No commercial re-use.

However, how SFN affects UVB-mediated epigenome/DNA methylome and transcriptome changes in skin photodamage has not been fully assessed. Herein, we investigated the transcriptomic and DNA methylomic changes during tumor initiation, promotion, and progression and its impact and reversal by SFN using next-generation sequencing (NGS) technology. The results show that SFN reduced tumor incidence and tumor number. SFN's protective effects were more dramatic in the early stages than with later stages. Bioinformatic analysis of RNA-seq data shows differential expressed genes (DEGs) and identifies the top canonical pathways related to SFN treatment of UVB-induced different stages of epidermal carcinogenesis. These pathways include p53 signaling, cell cycle G2/M DNA damage checkpoint re
