Ceruminous gland adenocarcinoma. A light and electron microscopic study

Tumors of ceruminous gland origin in the external auditory canal are rare in man. A case is described in which such a tumor presented as an invasive vascular temporal bone neoplasm, mimicking a glomus jugulare tumor.

Description
Summary:Tumors of ceruminous gland origin in the external auditory canal are rare in man. A case is described in which such a tumor presented as an invasive vascular temporal bone neoplasm, mimicking a glomus jugulare tumor. Light and electron microscopic study of this tumor confirmed a diagnosis of ceruminous gland adenocarcinoma. Tumors of ceruminous gland origin appear to have a distinctive clinical behavior by virtue of their unique anatomical location in the external auditory canal. Our experience with this case establishes another clinical picture characterizing the histologic type of ceruminoma designated as a ceruminous gland adenocarcinoma. We feel that the generic term „ceruminoma,”︁ with its implied histologic subgroups, is useful to the clinician when he encounters a tumor arising from the modified sweat glands of the external auditory canal.
