In the LIQUENIA Clinical Trial a group of patients diagnosed with moderate-severe vulvar lichen sclerosus sclerosus who had not responded to first-line treatment (ultra-potent corticosteroid cream) were infiltrated with fat tissue (fat-derived stem cells) and their own platelet-rich plasma.

The results obtained in this group of patients (treatment group) were compared with another group of patients with the same characteristics but who were only treated with corticosteroid cream (control group).

This research work was the basis for the doctoral thesis: Treatment of vulvar lichen sclerosus using adipose tissue associated with autologous platelet-rich plasma.
