A 51-year-old female of East Asian descent presents with a 1-month history of a painless lump behind the left ear discovered incidentally after a brief febrile episode. Physical examination reveals a left post-auricular lump that is hard and fixed to the underlying bone, with no other similar lesion or systemic abnormality detected (Figs. 1, 2 and 3).
