Adequacy of surgical resection decided by the margin status is important in attaining a good local control and better survival in Head and neck Cancers. Conventionally, a measured distance between the tumor edge and the cut edge of the specimen is taken as the margin. A margin more than 5 millimeter (mm) is considered clear, less than 5 mm is close and less than one mm is denoted as involved. The concept of this adequacy varies between the different sites and subsites in head and neck. The purpose of this paper is to review the current evidence that describes the adequacy of surgical margin status and their variability among the sites and sub-sites in the head and neck. More »»

Verrucous lesions of the oral cavity can be of varied histopathology. The present study evaluates the clinico-pathological features of verrucous lesions of the oral cavity and analyzes the treatment outcomes. Materials and Methods: This is a retrospective study of 15 consecutive patients who presented with verrucous lesions of the oral cavity, during the 5-year period from January 2006 to December 2010. Demographic, clinico-pathological features, treatment details, and outcomes were analyzed. Results: Fifteen patients with verrucous lesions of the oral cavity were treated with surgery as the primary modality. The mean age was 62.8 years (range 35-85 years). Wide excision of the primary lesion with adequate mucosal and soft-tissue margins was carried out. Free-flap reconstruction was done in eight patients. All patients remain loco-regionally controlled with good functional speech and swallowing outcome. Conclusions: Verrucous lesions of the oral cavity are a distinct clinical entity with varied histopathology. A surgical excision with wide margins and appropriate reconstruction is necessary to optimize the disease and functional outcome More »»
