Adenoma da orelha média: relato de caso

Abstract

Trat a-se de relato de um caso de adenoma de orelha média em paciente jovem com perda auditiva de condução progressiva, massa retrotimpânica hiperêmica de evolução lenta e submetido a tratamento cirúrgico por mastoidectomia radical. Este tumor é raro, composto de células epiteliais glandulares e neuroendócrinas. O diagnóstico diferencial é vasto, sendo este definido através do exame anatomopatológico e de imunohistoquímica. O tratamento é cirúrgico, não havendo necessidade de terapia adicional, somente acompanhamento pós-operató-rio rigoroso, uma vez que seu prognóstico é favorável. We describe a case report of a middle ear adenoma in man with progressive conductive hearing loss, hyperemic retrotympanic mass with slow growing and undergone a radical mastoidectomy. This is a rare tumor composed of adenomatous and neuroendocrine cells. It has a large number of differential diagnoses and it is done by microscopy and immunohistochemistry. The treatment is surgical in all cases with no additional therapy only clinical follow-up, once its prognostic is favorable. Rev Bras Otorrinolaringol.

“…In 1980, Murphy et al first reported a middle ear adenoma with neuroendocrine differentiation, also called carcinoid tumor, as various denominations are used for these neoplasias, reflecting the controversy between its presumed histogenesis and differentiation 3 . The lesion had adenomatous histological characteristics, but with ultrastructural neuroendocrine differentiation 1 4 .…”
