Ceruminous glands in ear meatus of domestic fowl: morphology, histochemistry and ultrastructure.
A case of ceruminous adenocarcinoma of the external auditory canal presenting as an aural polyp.
gland carcinomas: A clinicopathologic and immunophenotypic study of 17 cases.
Adenoid cystic carcinomas of the ceruminous
gland (ACCCGs) are morphologically similar to the more commonly encountered salivary gland tumors.
adenoma is classified as a well differentiated, benign neoplasm, localized, occasionally cystic and showing papillary proliferation of glands histologically similar to normal ceruminous
With the exception of ceruminous
adenocarcinoma, other neoplasms are rarely identified in this location.
Its location and the patient's age rendered the diagnosis of ceruminous
adenoma unlikely, and protein expression confirmed that the mass was a NAME tumor.
glands are modified apocrine glands found in deep dermis of external ear canal that produce a brown waxy material and cerumen.

First, aural toilet to remove otorrhea and ceruminous
and squamous debris improves drug delivery by clearing a path to the middle ear.
The consequences of these factors include a reduction in skin elasticity, atrophy of the ceruminous
and sebaceous glands, the loss of protective films and secretions, and a chemical imbalance (i.
Cerumen refers only to the secretory product of the ceruminous
glands in the external auditory canal, and it is just one component of earwax.
