Lipomatous pleomorphic adenoma of the ceruminous gland.
A case of lipomatous pleomorphic adenoma in the ceruminous gland is reported. A 69-year-old Japanese woman presented with a mass in the posterior wall of the cartilaginous external auditory canal. Light microscopic examination revealed a well-circumscribed tumor composed of tubular structures with apocrine secretion and ceroid deposition, extensive mature adipocytes, and spindle-shaped myoepithelial cells in the myxoid and fibrous stroma. This case demonstrates the peculiar location of a lipomatous pleomorphic adenoma in the external auditory canal.
