(Proliferative verrucous leukoplakia(PVL): A case report)

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). In our study we reported a case of PVL which is first described by Hansen et al in 1985. PVL is described as a continuum of hyperkeratotic disease, and is an unusual , multi-fokal, progressive form of oral leukoplakia with high malignant potential as well as mortality rates. We treated the patient with diode laser therapy because of its advantages( i.e. reduced enfection risk, edema and post operative analgesia effect and elimination of tumor malformationtendency and less invasive approach versus conventional surgery techniques). Given the high tendency for oral squamous cell carcinomas( OSCC) to appear in these patients, they should be checked for life at least once every 6 months.
