Mucocele mimicking a Warthin's tumour recurrence.

We report an unusual case of an extravasation mucocele complicating superficial parotidectomy. The tumour excised was a Warthin's tumour. Three months following the primary surgery a cystic lesion appeared in the parotid bed. It was initially thought to represent a recurrence. The area was re-explored and a mucocele excised. The pathogenesis of mucoceles and the difficulties encountered when dealing with parotid tumour recurrence are discussed.
