Early symptoms of nasopharyngeal carcinoma (NPC) can often be deceptive and confusing. Most patients with nasopharyngeal carcinoma present at an advanced stage with metastatic cervical nodes present at the time of diagnosis. A deep neck abscess as the presenting feature has not been reported. We report two cases of nasopharyngeal carcinoma which presented with retropharyngeal abscesses and persistent lymphadenopathy. These two patients illustrate that refractory lymphadenopathy, despite adequate treatment of the associated infection, should prompt a search for underlying disease. The relationship between nasopharyngeal carcinoma and retropharyngeal abscess is discussed.

Retropharyngeal abscesses in adults are very rare and usually secondary to chronic tuberculous cervical spine osteomyelitis. We report a case of Staphylococcus aureus septicaemia with multifocal abscesses and osteomyelitis of the cervical spine causing a retropharyngeal abscess. This presented as neck pain and dysphagia following a fall. In addition, we have reviewed related cases.

An unusual case of an adult female with anorexia nervosa, who developed a retropharyngeal abscess, is presented. This case is reported both because of the paucity of reports on retropharyngeal abscess and because of the dramatic unusual aetiology.
