LIHNCS - Lugol's iodine in head and neck cancer surgery: a multicentre, randomised controlled trial assessing the effectiveness of Lugol's iodine to assist excision of moderate dysplasia, severe dysplasia and carcinoma in situ at mucosal resection margins of oral and oropharyngeal squamous cell carcinoma: study protocol for a randomised controlled trial.

Background: Oral cavity and oropharynx cancer are increasing in incidence worldwide but survival outcomes have not significantly improved over the last three decades. The presence of dysplasia or carcinoma in situ at surgical margins following resection of squamous carcinoma of the mucosal surfaces of the head and neck has been shown to be associated with a higher incidence of local recurrence and reduced survival. While invasive carcinoma in mucosal surfaces can usually be distinguished from adjacent normal mucous membrane, pre-malignant disease is much less readily distinguished at operation.

First report of squamous cell carcinoma arising within an intraoral radial forearm free flap.

Introduction: Oral epithelial dysplasia within free tissue reconstructions of the oral cavity has been reported. We report a case where squamous carcinoma arose within radial forearm skin transferred to the oral cavity 23 years previously. After a thorough literature search we believe this is the first report of such a phenomenon.

Small cell neuroendocrine tumour of the anterior tongue: A case report.

Introduction: Neuroendocrine carcinomas (NECs) are rare in the oral cavity. There is ambiguity regarding the classification of these tumours, but their aggressive nature is recognised throughout the literature. Merkel cell carcinoma (MCC) is rare and more frequent in skin, though it has also been described intra-orally.
