BACKGROUND Chronic graft-versus-host disease is a serious complication of allogeneic hematopoietic cell transplantation, and the mouth is one of the affected sites. OBJECTIVE The aim of this study was to evaluate the oral features of this disease after hematopoietic cell transplantation. METHODS This was a cross-sectional multicenter study that enrolled patients submitted to transplantation...

Oral lichenoid lesion (OLL) is a that causes cell-mediated immune tissue reactions, and very similar to oral lichen planus (OLP). This disease can be distinguished from OLP when the cause clear. OLL often caused by dental metals, drugs diseases such as graft-versus-host disease(GVHD). The clinical histopathological differences between are still under debate. In this study, findings of 11 cases ...

We investigate Support Vector Machines (SVM ) in the context of oral lesion classification using digital color images as input. Two common lesions of similar visual appearance to the human observer were evaluated: oral leukoplakia, which is a potentially pre-cancerous lesion, and oral lichenoid reactions (with subclasses of atrophic, plaqueformed and reticular reactions), which are usually harm...

Introduction: Different oral lesions have clinical characteristics which in some cases are similar. Therefore, in these cases histopathological examination for correct diagnosis is necessary. The aim of this study was to evaluate the compatibility rate of clinical and histopathological diagnosis of oral lesions in Zahedan School of dentistry. Methods: In this retrospective study, determination ...

Drug-induced lichenoid reaction is quite common in the oral cavity. Patients with oral lichenoid lesions (OLL) may increase risk of developing epithelial dysplasia and squamous cell carcinoma. Although this subject remains controversial, several studies suggested that the overall rate of malignant transformation of OLL was greater than that of general population or patients with oral lichen pla...

UNLABELLED Graft versus host disease (GVHD) is a common complication in bone marrow transplant (BMT) patients. It is characterized by systemic and oral cavity alterations. Depending on the timing of lesions, GVHD is classified as acute or chronic. Alterations in the oral cavity are lichenoid reticular lesions, erythema, ulcerations, and xerostomia. Sporadically, mucocele and pyogenic granulomas...

Background: Chronic graft versus host disease (ch.GVHD) is the most frequent late complication after allogenic stem-cell transplantation. Systemic immunosuppressive agents are usually required to control the disease. Psoralen plus UVA (PUVA) has been used for the treatment of ch.GVHD with variable beneficial effects. The objective of this study was to assess the efficacy and safety of a r...
