gland carcinomas: a clinicopathologic and immunophenotypic study of 17 cases.
adenocarcinoma with extensive parotid, cervical, and distant metastases: case report and review of literature.
carcinomas are extremely rare and tend to present as a mass or with otalgia.
purulent secretions in 4 external ear canals (of which, insipissated pus in 1 external ear canal), ceruminous
secretions in 3 external ear canals, ulceration in 3 external ear canals and excessive hair that were grossly invisible in 4 external ear canals.
adenoma is a benign glandular neoplasm of ceruminous
glands that arises solely from the external auditory canal.
adenoma accounts for <1% of all external ear tumors, usually affecting middle-aged (mean, 55 years) patients, without gender predilection.
It has been proposed that these tumors arise from the ceruminous
glands, which are modified apocrine glands with some eccrine functions.
Pathology was thought to be consistent with a ceruminous
Malignant neoplasms of ear canal in dogs and cats are most commonly carcinomas of ceruminous
gland and squamous cell and of undetermined origin (Legendre etal, 1981; Withrow et al., 1996).
Histologically the tumor was confirmed as ceruminous
Common primary neoplasms of the external auditory canal include ceruminous
adenoma, adenoid cystic carcinoma, ceruminous
adenocarcinoma, and pleomorphic adenoma.
Systematically administered glucocorticods may help control the primary cause of inflammation, subsequent swelling or ceruminous
gland hyperplasia that may occur with otitis externa (Morris, 2004).
