dc.description.abstract Background: Local deficit of several biomolecules have been described in oral lichen planus (OLP). Such a deficit impairs cellular functions and cell-matrix communication. Purpose: Assess the efficacy of the local application of autologous biomolecules in the treatment of erosive OLP. Materials and methods: In this study, the use of plasma rich in growth factors (PRGF) as a source of blood-derived and autologous growth factors and proteins were tested in erosive oral lichen planus refractory to corticosteroids. Histopathological features of the disease were also analysed at the time of diagnosis. Clinical data were the number of recurrences and achievement of pain reduction and complete healing of the lesions. A total of 10 patients with erosive OLP refractory to treatment by corticosteroids were included in the study. All patients were females with a mean age of 48 ± 12 years. Results: A complete remission of the disease was achieved after one infiltration of PRGF in 8 patients. Only 2 patients required a total of 2 infiltrations to heal. Hydropic degeneration of the epithelium basal layer, band-like subepithelial lymphocytic infiltration and fibrin deposits in the epithelium were observed in all patients. Interestingly plasma cells were present in 2 patients. All patients presenting plasma cells healed after only one PRGF infiltration. However, 2 patients out of 6 (no plasma cells) required 2 infiltrations. Conclusions: The local administration of autologous local factors could overcome the deficit of biomolecular clues and thus improve cell functions and restore cell-matrix communication. spa
