Objectives. Chronic Graft-Versus-Host Disease (cGVHD) is an immunoregulatory disorder which occurs after allogeneichematopoietic-cell transplantation (HCT) and often shares features of autoimmunity and immunodeficiency.GVHD related oral manifestations include severe oral pain, xerostemia, ulcerative lesions, and mucositis. Furthermore,a major late suggested complication of HSCT is the dramatically increased risk of secondary malignancies includingoral cancer and oral cGVHD-releted inflammation may be considered a potential risk factor.Case report. A 51-year-old male patient referred in 1994 to our surgery for cGVHD oral lesions secondary to HCT for acute myelogenous leukemia developed in 1992. In 2010, an incisional biopsy in left retrocommissural region for an erosive lesion was performed and microscopic analysis revealed an intense lymphoplasmacytic inflammatoryinfiltrate. In 2011, clinical intraoral examination revealed white verrucous plaque lesion associated with ulcerations on the gingiva of the V sextant and on the lower labial mucosa; two incisional biopsies of oral mucosa and an incisional skin biopsy were performed. Microscopic analysis revealed a well differentiated SCC, a moderatelydifferentiated SCC and a skin high grade dysplasia. Patient was surgically treated and is currently in follow up. Conclusions. Several authors suggest that cGVHD-related inflammation could be an important risk factor for carcinogenesis,also for oral cavity. Then it is recommended close follow-up to all patients treated with HCT, particularly when they develop graft-versus-host disease, and any suspicious oral lesions should be biopsied to rule out dysplasiaor malignancy.
