White lesions usually contain an increased amount of keratin. Some are rare congenital conditions, such as white sponge naevus and dyskeratosis congenita, unlikely to be seen in general dental practice. Inflammatory causes include candidosis and hairy leukoplakia, both now common in HIV disease. Non-infective causes include the common lesion of lichen planus, and the less common condition lupus...

Oral leukoplakia (OL) is the most common potentially malignant disorder of the oral mucosa. The etiological role of Candida in leukoplakia has been a subject of debate in recent years. Candida invasion has been suggested to be a significant risk factor for malignant transformation of OL and also it may be associated with certain clinical characteristics such as lesion type, size, and site, dysp...

We present a case of a 45-year-old patient who reported bleeding hemorrhoids. He had grade II hemorrhoids and was found to have a circumferential leukoplakic lesion at the anal verge. The patient had no symptoms of leukoplakia. The hemorrhoids were ablated with an Ellman radiowave device. Histological findings of the incised lesion from the verge showed hyperkeratosis and acanthosis extending c...

OBJECTIVE To describe the incidence of HPV in diffuse high grade pre-cancerous lesions of the larynx. METHODS Patient charts were searched for those who presented between October 2008 and June 2009 with diffuse vocal fold leukoplakia. Biopsy proven laryngeal lesions with high grade dysplasia or carcinoma-in-situ (CIS) were examined for patient characteristics and presence of high-risk type HP...

Free radical induced lipid peroxidation has been implicated in pathogenesis of several pathological disorders. Lipid peroxidation products malonaldehyde (MDA) was analyzed in 25 patients of leukoplakia, 47 patients of oral submucous fibrosis, 21 patients of candidiasis, 67 patients of dental caries, 62 patients of oral cancer and 50 patients of healthy subject served as a control. Significantly...

Precancerous lesions of oral mucosa, known as potentially malignant disorders in recent years, are consists a group diseases, which should be diagnosed the early stage. Oral leukoplakia, submucous fibrosis, and erythroplakia most common mucosal diseases that have very high transformation rate.

BACKGROUND We evaluated factors that affect malignant transformation of leukoplakia in a sample of the Iranian population. METHODS The records of patients with a clinical diagnosis of leukoplakia during a 20-year period from 1989-2009 referred to two of the largest referral centers in southern Iran were studied. Patients that developed malignant transformation were compared with patients that...
