RESUMO
Parapharyngeal space neoplasms tend to have a considerable volume by the time of diagnosis because of their deep location in the neck and may have a relatively long progression before becoming symptomatic. Common presenting signs and symptoms of parapharyngeal space neoplasms include swelling in the neck, intraoral mass, dysphagia, dysphonia, heaviness in the ear, otalgia, and rarely, trismus. Some of these signs and symptoms could be mistaken for signs of temporomandibular disorder (TMD). This clinical report presents the incidental discovery of parapharyngeal space carcinoma initially presenting as TMD. A thorough clinical examination of the temporomandibular joints, supported by their magnetic resonance imaging, led to early detection of the neoplasm, thereby improving the patient's post-treatment survival probability.
