Squamous cell carcinoma (SCC) of the tonsil is the most common malignant tumour of the oropharynx. Paediatric tonsillectomy is one of the most commonly performed procedures in Otorhinolaryngology. SCC of the tonsil remnant (SCCTR) in a previously tonsillectomised patient is rare.

Retrospective review of patients with SCCTR presenting to the Otorhinolaryngology, Head and Neck Unit January 2000 to December 2007.

Two hundred and fifty patients with tonsil SCC were identified. Ten (4%) of these had previously undergone tonsillectomy in childhood. Nine patients underwent radical treatment including surgery, radiotherapy and in four cases concomitant chemotherapy. Eight patients are alive with no signs of recurrence with follow-up of a minimum of 24 months. One has been lost from follow-up.

Clinicians should be aware that SCC can arise from a tonsillar remnant. SCCTR has similar oncological outcomes as tonsillar tumours.
