Abstract: Background/Objectives: Rendu–Osler disease is a rare genetic disease, characterized by widespread telangiectasia that can involve the skin and mucous membranes. The diagnosis is based on spontaneous and recurrent epistaxis; various mucosal and cutaneous telangiectasia at typical sites; visceral manifestations including gastrointestinal telangiectasia or pulmonary, cerebral, or hepatic arteriovenous malformation; and a first-degree relative with hereditary hemorrhagic telangiectasia. Squamous cell carcinoma of the larynx generally develops in patients with a smoking history. It is most often treated by surgery and/or radiotherapy. To our knowledge, these two entities were never reported in the same patient. Methods: We herein report a case of a 51-year-old man with Rendu–Osler disease. He was subsequently diagnosed with a locally advanced well-differentiated squamous cell carcinoma of the vocal cord. Results: The patient received a neo-adjuvant chemo-immunotherapy, with nine weekly injections of paclitaxel (60 mg/m2/week), cisplatin (30 mg/m2/week), and cetuximab (250 mg/m2/week), and three injections of pembrolizumab (200 mg every 3 weeks). This controlled tumor bleeding, and then cisplatin-enhanced radiotherapy helped obtain a complete remission. Conclusions: Locally advanced squamous cell carcinoma of the larynx treatment in the context of active Rendu–Osler disease is challenging. If the wide curative surgical approach is deemed too risky, neo-adjuvant chemo-immunotherapy may present a helpful alternative as it may enhance the conditions in order to perform classical radiotherapy with concomitant cisplatin.
