Oral lichenoid contact lesions related to dental metal allergy may resolve after allergen removal.

Background/ Purpose: Distinguishing oral lichenoid contact lesions (OLCLs) from oral lichen planus (OLP) is challenging. This study aimed to identify clinicopathological findings to distinguish OLCLs from OLP, and to evaluate the effectiveness of removing metal allergens in the treatment of OLCLs.

Materials And Methods: This study retrospectively evaluated 30 patients diagnosed with OLCLs, and 30 age- and sex-matched OLP patients.

Malignant transformation of oral lichen planus: a retrospective study of 565 Japanese patients.

Background: Oral lichen planus (OLP) is a chronic inflammatory oral mucosa disease that is recognized as an oral potentially malignant disorder. However, the potentially malignant nature of OLP remains unclear.

Methods: We designed this study to examine the demographic and clinical characteristics of patients with OLP and evaluate the associated malignant transformation rate.

Oral granuloma in a pediatric patient with chronic graft-versus-host disease: A case report.

Background: Oral mucositis is often observed with graft-versus-host disease (GVHD); however, the occurrence of oral granuloma is rare. The rapid increase in granulomatous lesions should be distinguished from malignant tumors in patients with GVHD because malignant diseases can develop in those patients. This case is the youngest pediatric patient with granuloma associated with GVHD.

Long-term outcome of non-surgical treatment in patients with oral leukoplakia.

Unlabelled: The standard treatments for oral leukoplakia range from careful observation to complete resection. No surgical intervention is chosen for several supposable reasons. Surgical treatment and no surgical treatment for oral leukoplakia have no defined basis for comparisons, and few studies have reported on the long-term outcomes of oral leukoplakia without surgery.
