The histologic examination of tumor-like formations in the external auditory canal, frequently observed in association with chronic suppurative otitis media, may yield information of diagnostic, prognostic and corroborative clinical importance. It is well recognized that neoplastic formations such as carcinoma, specific granulomas associated with tuberculosis and syphilis, and manifestations of metabolic disorders may be combined with chronic suppuration of the middle ear. These groups will be discussed briefly with emphasis on certain points of clinicopathologic interest. The main purpose of this communication is to encourage a renewal of interest in the benign neoplastic formations and perhaps a new interpretation of their clinical significance.
Malignant neoplasms affecting the middle ear are relatively frequent. The literature shows a paucity of material on the subject, and even any reference there to "primary" carcinoma of the middle ear requires explanation. Proof of the occurrence of such a neoplasm is most difficult. Notably do
