Microdeletion of the entire IRF6 gene in a Subsaharian African's family with Van der Woude syndrome.

Microdeletion of the entire interferon regulatory factory 6 (IRF 6) gene is a rare cause of Van der Woude syndrome (VDW) with only few cases reported in medical literature. Its occurrence in multiple affected members of a family is exceptional. The aim of this presentation was to describe a Central African family with typical VDW phenotype carrying an IRF6 gene deletion.

Axillary lymph node metastasis in second oropharyngeal cancer.

Background: The risk of metastasizing in axillary lymph node is occasional in the head and neck cancers. This pattern of spread is difficult to explain and totally unpredictable even for these lymphophilic cancers.

Observation: A 72-year-old patient benefited, 11 years ago, of surgical oncology care associated with adjuvant radiotherapy for squamous cell carcinoma of the left floor of the mouth (pT4 pN2b M0).
