The goal of this multicenter retrospective observational study is to provide an inventory of the specific and non specific cord vocal lesions that can cause dysphonia in patients with systemic autoimmune diseases. The main question it aims to answer is:
* What are the main cord vocal lesions responsible for dysphonia in patients with a systemic autoimmune disease? * Is there a diagnosis delay regarding those lesions? * How are those lesions managed? Participants suffering from dysphonia in a context of a systemic autoimmune disease will be identified, with a review of their medical record.
