Ceruminous Gland Adenoma of External Auditory Canal- A Case Report

Ceruminous Adenoma (CA) is a benign neoplasm of ceruminous glands. Developing exclusively in the external auditory canal (EAC) with benign clinical behavior and was first reported by Hang in 1894. It is rare in humans and poses a diagnostic problem for the clinician, due to the variety of clinical presentations. This tumor is mainly composed of the ceruminous gland cells (modified apocrine sweat glands). These glands are localized deep in the skin mostly in the cartilaginous part of the external auditory meatus. We are presenting a 45 year old female patient who was referred to our otology department with a two year history of right ear blockage with progressive hearing loss, her other medical history was unremarkable. The surgical finding under microscope showed soft tissue mass under the skin that fulfilled half of the posterior inferior portion of the external auditory canal (EAC) that was completely excised under general anesthesia utilizing a postaurical approach. The excised tumor specimen after proper staining confirmed the diagnosis of ceruminous adenoma. In conclusion the CA is benign rear tumor raised from ceruminous gland in EAC slowly growing when getting bigger can block the EAC leading to heating loss; it can be presented with variety of symptom such as mild otolgia, ear blockage sensation and hearing loss treatment of choice is complete excision along with over line skin to prevent recurrence.
