“…Oral cGVHD manifests in 45–83% of transplant patients, and the most important clinical manifestations are represented by lichenoid oral mucositis, Sjögren-like signs, and scleroderma. In particular, with regard to lichenoid changes, they are frequently localized in the labial and buccal mucosa, the tongue, and the palate with different clinical aspects—atrophic, erythematous, erosive, ulcerative, keratotic reticular-, or plaque-type—with or without pain [ 9 , 10 , 11 ]. Furthermore, in patients with oral cGVHD, there is a greater incidence of pyogenic granuloma, verruciform xanthoma, and oral squamous cell carcinoma (OSCC) [ 5 , 12 ].…”
