Characterization of Oral Involvement in Acute Graft-versus-Host Disease

AbstractAcute graft-versus-host-disease (aGVHD) is a major complication of allogeneic hematopoietic stem cell transplantation (HSCT). The purpose of this study was to characterize the oral features associated with aGVHD in patients who underwent HSCT between 1995 and 2010 and developed prominent oral aGVHD. Data was collected from patient medical records and analyzed descriptively. Twenty-one cases were identified, of which 5 (24%) demonstrated only oral features; the remaining 16 had variable involvement of skin (n = 14), liver (n = 7), and gut (n = 5). The median time to onset of any sign of aGVHD was 22 days (range, 8 to 154 days), and that for onset of oral aGVHD was 35 days (range, 11 to 159 days). Sites affected by nonspecific erythema and ulcerations included buccal mucosa (19 of 21; 90%) tongue (18 of 21; 86%; dorsum in 8), labial mucosa (16 of 21; 76%), palatal mucosa (15 of 21; 71%; hard palate in 7), and floor of mouth (7 of 21; 33%). Eight cases (38%) presented with lip ulceration and crusting. In addition to systemic therapies, topical solutions of dexamethasone, tacrolimus, and morphine were used for ancillary support. Oral features of aGVHD may be the initial manifestation and include nonspecific erythema and ulcerations of keratinized and nonkeratinized mucosa and lips. Intensive topical therapies may help reduce symptoms and promote healing
