Lymphoma Invading the Anterior Eustachian Tube: Temporal Bone Histopathology of Functional Tubal Obstruction

摘要: The temporal bones of a man with poorly differentiated lymphocytic lymphoma, who had bilateral conductive hearing loss and incomplete left-sided facial palsy, were obtained. Sections prepared for histologic study by staining hematoxylin eosin examined under the light microscope. left bone showed marked tumor cell involvement, not only lateral part cartilaginous portion eustachian tube (ET) where tensor veli palatini muscle been partially destroyed, but also in anterior bone. A serous middle ear effusion was present, lumen ET unaffected or inflammation. pathological findings right similar to those left, although its surrounding structures available study. pathogenesis otitis media appeared be secondary functional obstruction, due dysfunction pa...
