Metastatic rectal adenocarcinoma in the external auditory canal. [JOURNAL ARTICLE]
J Laryngol Otol 2008 Jun 4.:1-2.
Objectives:To present a rare case of rectal adenocarcinoma metastasising to the external auditory canal, in a patient in whom computed tomography staging of the abdomen, chest and pelvis was clear for metastatic disease.
Methods:Case report and review of the literature.
Conclusions:Metastatic tumours to the external auditory canal are rare, with rectal adenocarcinoma being one of the rarest. However, it is important that the external auditory canal is regarded as a potential site for metastasis, even when computed tomography staging is clear. Metastatic tumour should be included in the differential diagnosis of a patient presenting with an ear mass.
