DISCUSSION White lesions are relatively frequent in the oral cavity with prevalence of approximately 24.8% Among them oral leukoplakia (OL) is quite prevalent (0.2-3.6%) In a retrospective study, Hansen et al ., reported that 26 of the 30 lesions initially diagnosed as OL became oral carcinomas in patients followed for 1-20 years (average, 6.1 years). After this study, these lesions were named oral proliferative verrucous leukoplakia (OPVL) According to the latest World Health Organization nomenclature, OPVL conforms to the new terminology of “potentially malignant disorders” given that it is neither a delimited lesion nor a condition It is best-defined as a continuum of oral epithelial disease with hyperkeratosis at one end of a clinical and microscopic spectrum and verrucous carcinoma or squamous cell carcinoma at the other
Etiopathogenesis Many potential etiologies have been hypothesized, but little has been proved about the origin of this disease process The disease seems to be idiopathic Tobacco is frequently absent as a known risk factor as OPVL occurs both in smokers and non-smokers An association has been reported between human papillomavirus (HPV) and OPVL Between 0% and 89% of OPVL are reported to be HPV positive, especially for HPV types 16 and 18 Apparently, there is no unequivocal pathogenetic link between HPV and OPVL and it has also been reported in association with Epstein-Barr virus or candida infection Despite such extensive works, the etiology of OPVL is still as enigmatic as the disease itself
Clinical features Two of the largest studies of OPVL patients reported a predilection for this lesion in elderly women, with a ratio as high as 4:1 for women to men unlike other forms of OL. The mean age at the time of diagnosis is slightly over 60 years It has been shown that almost all lesions occur bilaterally, mainly affecting the lower alveolar ridge and buccal mucosa Clinically, it generally presents as a simple benign form, which tends to spread and become diffuse In time, OPVL develops exophytic , wart-like or erythroplakic areas that become oral carcinomas
Histopathological features The microscopic findings associated with OPVL are dependent on the stage of the disease and the adequacy of the biopsy Hansen et al ., suggested histologic stages in the continuum of OPVL with intermediates Grade 0: Normal mucosa Grade 2: Hyperkeratosis (clinical leukoplakia ) Grade 4: Verrucous hyperplasia Grade 6: Verrucous carcinoma Grade 8: Papillary squamous cell carcinoma Grade 10: Less well-differentiated squamous cell carcinoma Batsakis et al ., reduced the number of histologic stages to four with intermediates: Grade 0: Clinical flat leukoplakia without dysplasia Grade 2: Verrucous hyperplasia Grade 4: Verrucous carcinoma Grade 6: Conventional squamous cell carcinoma with intermediates
It is of interest that the early phase of these lesions usually exhibits an interface lymphocytic infiltrate that may have a pronounced lichenoid pattern characterized by basal vacuolar degeneration containing apoptotic cells and eosinophilic bodies, similar to types of oral lichenoid stomatitis such as lichen planus Therefore, OPVL has no single defining histopathologic feature Diagnosis Because of the lack of specific histological criteria, the diagnosis of OPVL is based on combined clinical and histopathologic evidence of progression In previously published series, diagnosis of OPVL was made according to Hansen's et al ., definition There are few studies that apply a set of diagnostic criteria that are mentioned as follows
Ghazali et al ., established the following criteria: The lesion starts as homogenous leukoplakia without evidence of dysplasia at the first visit With time, some areas of leukoplakia become verrucous The disease progresses to the development of multiple isolated or confluent lesions at the same or a different site With time, the disease progresses through the different histopathological stages reported by Hansen et al .[ 2 ] The appearance of new lesions after treatment A follow-up period of no less than 1 year. Gandolfo et al ., establish the following criteria: An initially innocuous lesion characterized by a homogenous plaque that progresses over time to an exophytic , diffuse, usually multifocal, lesion with a verrucous epithelial growth pattern Histopathologically , proliferative verrucous leukoplakia (PVL) changes gradually from a simple plaque of hyperkeratosis without dysplasia to verrucous hyperplasia, verrucous carcinoma or oral squamous cell carcinoma (OSCC).
Cerero-Lapiedra et al ., established the following major and minor criteria: Major criteria A leukoplakia lesion with more than two different oral sites, which is most frequently found in the gingiva , alveolar processes and palate The existence of a verrucous area That the lesions have spread or engrossed during development of the disease That there has been a recurrence in a previously treated area Histopathologically , there can be from simple epithelial hyperkeratosis to verrucous hyperplasia, verrucous carcinoma or OSCC, whether in situ or infiltrating. Minor criteria An OL lesion that occupies at least 3 cm when adding all the affected areas That the patient be female That patient (male or female) be a non-smoker A disease evolution higher than 5 years
In order to make the diagnosis of PVL, it was suggested that one of the two following combinations of the criteria mentioned before were met. Three major criteria (being E among them) or Two major criteria (being E among them) + two minor criteria. Nevertheless, at present, there is no criterion that will allow for the early diagnosis of the disease Treatment Advise patients with OPVL to avoid other known factors associated with development of oral carcinoma, such as tobacco, alcohol and betel.
Medical care Owing to the progressive nature of OPVL, many forms of therapy used for the management of traditional leukoplakia have been disappointing. Carbon dioxide laser, radiation, topical bleomycin solution, oral retinoids , beta-carotene and systemic chemotherapy have all failed at achieving permanent cure. Methisoprinol is a synthetic agent capable of inhibiting viral ribonucleic acid synthesis and replication and of stimulating antiviral cell–mediated reactions that has been shown to have some clinical efficacy in HPV-induced lesions. Although improvements have been noted with some of these modalities, recurrence rates after cessation of therapy are high, often within months of discontinuation of treatment
Surgical care This lesion is resistant to the presently available treatment modalities; therefore, total excision with free surgical margins is critical combined with a lifelong follow-up Malignant transformation and recurrences OPVL is known for its aggressive pathology, given its multifocal involvement, high malignant transformation rates (60-100%), frequent recurrences (87-100%) and high mortality rates (30-50%) The gingiva and palate represented the areas with the highest frequency of these multiple malignant tumors Given the high tendency for (OSCCs) to appear in these patients, they should be checked for life at least once every 6 months
