BACKGROUND: Cancer-associated fibroblasts (CAFs) are generally associated with negative prognostic factors. This study compares the clinicopathologic impact of CAFs in oral squamous cell carcinoma in patients with a history of proliferative verrucous leukoplakia (p-scca) and patients with conventional squamous cell carcinoma of the buccal mucosa, gingiva, and palate (c-scca). METHODS: A retrospective clinicopathologic and immunohistochemical analysis of 97 tumor specimens from 78 patients (13 patients with proliferative verrucous leukoplakia-associated squamous cell carcinoma (n = 32) and conventional squamous cell carcinoma from the buccal mucosa, gingiva, and palate (n = 65) was conducted...

BACKGROUND: Oral leukoplakia is the most common potentially malignant disorder in the oral cavity and can precede carcinoma. This study aimed to identify possible oral leukoplakia salivary biomarkers. METHODS: Unstimulated saliva was collected from participants and protein concentration was determined. Proteins were then precipitated with cold acetone and separated using 2DE over a pH range of 3-10. Spot demarcation and matching were performed and protein identification was done through MS analysis...

Proliferative verrucous leukoplakia (PVL) is a rare form of oral leukoplakia, which was first described in 1985 by Hansen et al. Since then, various published case series have presented PVL as a disease with aggressive biological behavior due to its high probability of recurrence and a high rate of malignant transformation, usually higher than 70%. PVL is a long-term progressive condition, which is observed more frequently in elderly women, over 60 years at the time of diagnosis. The buccal mucosa and tongue are the most frequently involved sites...

Lichenoid changes in the oral mucosa can be encountered in a wide range of lesions and can have varied etiologies. Immune-mediated disorders, including lichen planus, mucous membrane pemphigoid, discoid lupus erythematosus, and graft-versus-host disease, can have clinical and histologic overlaps. Lichenoid reactions to dental materials, such as amalgam, or to many systemic drugs are also well documented. Dysplasia of the oral cavity at times can also express a lichenoid histology, which may mask the potentially cancerous component...

Proliferative verrucous leukoplakia is an intriguing disease, which occurs particularly in women aged greater than 60 years, is not associated with tobacco and alcohol, and has a high risk of recurrence and malignant transformation. Although it is well known that the typical presentation is characterized by multifocal and verrucous white lesions, there is no description that its initial clinical presentation may simulate a lichenoid reaction.

Proliferative verrucous leukoplakia is a distinct precancerous condition with a high rate of recurrence and malignant transformation over time. Proliferative verrucous leukoplakia has no specific histopathologic presentation; therefore, emphases must be on clinical presentation and history to make a diagnosis; giving the need for a high clinical suspicion. This condition is very important for the general dentist to recognize. Here we describe the clinical and microscopic features of seven cases of proliferative verrucous leukoplakia, with two cases which demonstrated malignant transformation (hybrid carcinoma and squamous cell carcinoma)...

BACKGROUND: Cytokines and chemokines have been analysed in patients with oral squamous cell carcinoma and potentially malignant disorders. We selected interleukin-6 (IL-6) because it is a multifunctional interleukin reported to be altered in potentially malignant oral disorders and in malignant lesions. To date, this has not been evaluated or tested in proliferative verrucous leukoplakia (PVL), however. OBJECTIVES: This study aimed to analyse the differences in serum and saliva IL-6 levels among patients with PVL, oral squamous cell carcinoma (OSCC) and healthy controls and to examine the relationship between salivary IL-6 levels and the extent of the verrucous area...

Human papillomaviruses (HPVs) are epitheliotropic viruses with an affinity for keratinocytes and are principally found in the anogenital tract, urethra, skin, larynx, tracheobronchial and oral mucosa. On the basis of high, but variable frequency of HPV in oral squamous cell carcinoma (OSCC), malignant potential of HPV infection has been hypothesized but not definitely confirmed. The aim of this review was to highlight the genomic structure and possible mechanism of infection and carcinogenesis by HPV in the oral mucosa and to review the frequency of HPV prevalence in OSCC and oral potentially malignant disorders...

AIMS: Oral verrucous lesions, typically presenting as slowly enlarging, grey or white, warty, exophytic overgrowths on the buccal mucosa or gingiva may be verrucous carcinoma (VC), verrucous hyperplasia (VH), proliferative verrucous leukoplakia (PVL), or may show the conventional invasive pattern of squamous cell carcinoma (SCC). This study was undertaken with the aim to report the demography of different types of oral verrucous lesions and evaluate their long-term outcome. MATERIAL & METHODS: This clinical study comprised 15 patients with verrucous lesions of the oral cavity who underwent biopsy for confirmation of diagnosis...

The main purpose of this paper was to assess the current state of science on oral leukoplakia. Although it is considered a potentially malignant disorder the overall malignant progression of oral leukoplakia is of the order of 5% and even more. Nowadays there are no currently accepted markers to distinguish those that may progress to cancer from those that may not. The current golden standard is considered the presence of epithelial dysplasia on the tissue biopsy of the lesion. Proliferative verrucous leukoplakia is a rare form of OL which has multiple recurrences, is refractory to treatment and has malignant transformation in a short period...

OBJECTIVE: Proliferative verrucous leukoplakia (PVL), a potentially malignant disorder, often undergoes malignant transformation to oral squamous cell carcinoma. The aim of our study was to document and compare the histologic, immunohistochemical, and clinical features and the survival rates of carcinoma arising in patients with PVL (p-scca) with conventional squamous cell carcinoma (c-scca) in order to determine if p-scca should be categorized as a separate clinical entity. MATERIALS AND METHODS: A retrospective review of 11 patients with PVL, 38 with p-scca tumors and 49 with c-scca tumors: buccal mucosa (n = 28) and gingiva or palate (n = 21)...

AIMS: About 60% of the oral cancer arise on a pre-existent potentially malignant disorder of oral mucosa like the oral proliferative verrucous leukoplakia. The treatment with the photodynamic therapy of these lesions represents, in the last years, an innovative, non-invasive and effective therapeutic possibility to achieve the secondary prevention of oral cancer. In the last decade, case reports have described patients with similar treated through a photochemical reaction induced by laser light...
