[External auditory meatus adenocarcinoma].
We report the case of a man presenting a deafness and a hemorrhagic ear discharge since one year. CT scanner and MRI reveal an invasive tumoral lesion of the external auditory meatus (EAM) expending into the posterior fossa. After surgery the diagnosis of high grade ceruminal gland adenocarcinoma is established whereas the malignancy was not obvious on earlier biopsy. Cancers arising in the EAM are uncommon and are essentially representating by squamous cell cancers and basal cell cancers. The precise diagnosis of a glandular tumor is a challenge for the pathologist because the limits between benign and malignant tumors are not obvious. Integration of clinical and radiological behavior and the histology of the tumor is necessary for a early diagnosis and a complete surgery.
