[Pleomorphic adenoma causing a peritonsillar abscess]. / Pleomorft adenom som årsag til peritonsillær abscess.

Pleomorphic adenoma located in the soft palate is extremely rare. We report a 42-year-old woman, who presented to the ear nose & throat department with a mucosal swelling of the right soft palate mimicking a peritonsillar abscess. Drainage was attempted several times without significant results. Emergency tonsillectomy was carried out, which showed a tumour intraorally beside the right tonsil. The tumour and the tonsil were radically excised. Histological analysis of the tumour revealed a pleomorphic adenoma. At three-month follow-up the patient was doing well and MRI scan revealed a residual tumour of 6 mm.
