Instituto Nacional de Câncer, Hospital Central I: Neurologist; Neurosurgeon; Physiotherapist, Vestibular Rehabilitation Specialist; Neuroradiologist. A 27 year-old female patient with an external auditory canal lesion was diagnosed as ceruminous adenoma at the age of 17. She was operated on twice and underwent radiotherapy. The examination shows left prosopagnosia, ipsilateral deafness, and hemiglossoplegia. MRI depicts a heterogeneous lesion in the left temporal bone (Figure). “Ceruminoma” a term considered by some to be a defunct diagnosis is a rare, potentially malignant tumour, which presents itself as a yellow mass located to the external auditory canal in 90% of the cases. Treatment and prognosis depend on one of the eight currently recognized histomorphologic subtypes (ceruminous and pleomorphic adenoma, cylindrome, adenoid cystic, ceruminous and mucoepidermoide adenocarcinoma, eccrine cylindrome and syringocystiadenoma papilliferum).
