Neoplasms of the ear are rare.

A large variety of epithelial and mesenchymal tumours arise in the ear (external, medial, internal). 

All tumours are rare except basal and squamous cell carcinomas of the pinna (external ear).

The tumours of the external ear are mainly derived from skin and bone.

Neoplasm of the Ceruminous Glands:

Ceruminous glands are modified sweat glands, confined to the skin lining of the cartilaginous part of the external auditory meatus. Tumours arising from these glands are extremely rare.

Controversy still exists about nomenclature, classification, tissue of origin, and accurate diagnosis of these tumours.

The benign eccrine cylindroma should be included in the ceruminous gland tumour classification.

A wide excisional biopsy should be performed in every external auditory canal lesion. The terms 'ceruminoma' and 'cylindroma' should be avoided.

 

Classifications of ceruminous gland tumours :

Benign:  Ceruminous  Adenoma (ceruminoma) ; Pleomorphic adenoma ; Syringocystadenoma papilliferum ; Cylindroma.

Malignant:   Mucoepidermoid carcinoma ; Adenocarcinoma ; Adenoid cystic carcinoma
