Ceruminous gland

From Wikipedia, the free encyclopedia

Ceruminous glands are specialized sudoriferous glands (sweat glands) located subcutaneously in the external auditory canal , in the outer 1/3. Ceruminous glands are simple, coiled, tubular glands made up of an inner secretory layer of cells and an outer myoepithelial layer of cells. [1] They are classed as apocrine glands. The glands drain into larger ducts, which then drain into the guard hairs that reside in the external auditory canal . [2] Here they produce cerumen , or earwax, by mixing their secretion with sebum and dead epidermal cells. Cerumen keeps the eardrum pliable, lubricates and cleans the external auditory canal , waterproofs the canal, kills bacteria, and serves as a barrier to trap foreign particles (dust, fungal spores, etc.) by coating the guard hairs of the ear, making them sticky. [1]

These glands are capable of developing both benign and malignant tumors. The benign tumors include ceruminous adenoma , ceruminous pleomorphic adenoma , and ceruminous syringocystadenoma papilliferum . The malignant tumors include ceruminous adenocarcinoma , adenoid cystic carcinoma , and mucoepidermoid carcinoma . [2]
