Ceruminous gland adenocarcinoma in the ear canal of a 7-year-old mixed breed bitch. The mass originated in the ceruminous glands and developed inside the ear canal, causing it to distend without apparent invasion of the neighbouring tissues. In addition to a rich fibrous stroma, the mass exhibits a fibrous capsule with several areas of calcification.
