Although histologically benign, they can cause local infiltration and they also carry a risk of recurrence. We describe the case of an 11-year-old girl who presented with a desmoid tumor at the site of an old trauma, and we briefly review the literature of this lesion.展开更多

Methods:Surgically removed pathological scar tissue and the normal skin tissue removed due to extremity trauma in Sichuan Provincial People's Hospital between June 2014 and February 2017 were selected to detect the mRNA expression of TSG-6 as well as the protein levels of apoptosis genes and collagen metabolism indexes. Results: TSG-6 mRNA expression as well as Smac, p53, Cyt-C, IGF-1 and bFGF protein levels in pathological scar tissue was significantly lower than those in normal skin tissue while Livin, PCNA, Col-I, Col-III and TGF-β1 protein levels were significantly higher than those in normal skin tissue;Livin, PCNA, Col-I, Col-III and TGF-β1 protein levels in pathological scar tissue with higher TSG-6 expression were lower than those in pathological scar tissue with lower TSG-6 expression while Smac, p53, Cyt-C, IGF-1 and bFGF protein levels were significantly higher than those in pathological scar tissue with lower TSG-6 expression. Conclusion: The low expression of TSG-6 in pathological scar tissue can inhibit apoptosis and promote collagen anabolism to accelerate scar formation.展开更多
