Abstract

Background

There is only one previous case report of a poorly differentiated carcinoma arising from an adenolymphoma of the parotid gland (Warthin's tumour). The absence of clinical symptoms, and the aspecificity of the radiological pattern make the diagnosis very difficult.

Case presentation

We here report the case of a 73-year-old man with Warthin's tumour who was brought to our attention because of a swelling in the parotid region.

Conclusions

In this case with an atypical clinical presentation, the intra-operative examination of a frozen section of the parotid mass allowed us to diagnose the malignant tumour correctly and consequently undertake its radical excision.
